Main Features

Chao World Extended

Mod Name: !ChaoWorldExtended

The main mod of the pack, it adds objects to your garden, allows chao to climb walls, adds new TV Channels, and adds four unused toys (the Piano, Organ, Duck, and Float). It also fixes the Hero/Run and Hero/Power texture glitch, fixes planted trees not growing correctly in the port, and even provides a fix for the Bright Chao glitch that is in the Steam version of the game. This code must be enabled at all times in order for the rest of the mods/codes to work properly. It'll show up on your mod loader/manager as "Chao World Extended". Below are the Chao World Extended features included in the base mod.

Shiny Fruit

A new fruit is added to the game which, once eaten, allows Bright Chao to look like their intended Shiny Two-tone appearance and vice versa. It can be purchased from the Black Market for 3000 rings.


Day/Night Cycle

Day/Night Cycle is a mod that cycles the scenery through day, evening, and night, including having different weather. Neutral Chao and Hero Chao sleep at night, and Dark Chao sleep at day. If it's cloudy, Chao may have low boredom, so they won't play much. You can either set the garden to cycle through the different times or manually enable certain times in certain gardens. The time frame will be saved with your Chao save file when you're finished. This is not compatable with Dreamcast Gardens and most garden texture mods. As of version 9, this has shifted from being a separate add-on to being built into the base mod itself. In version 9.2, you can give the cycle a fade transition.

New Black Market

In version 9.4, the Black Market has received a massive makeover. What was once a single-page selection of items has now been changed. There is now multiple pages, or tabs, that can display 32 items each. Tabs exist for Eggs, Fruits, Seeds, Hats, Accessories, and more. The Black Market's item ID limit has also been increased to 65,535. In version 9.4.1, a timer was added that displays the amount of time remaining until the Black Market's stock changes. If the timer reaches 0 while you are on the Black Market's main menu, where the timer displays, the game will kick you out of the Black Market automatically, allowing you to see what has arrived in stock without having to manually exit yourself.

Cosmetic Wings

A new item that debuted in version 9.2. Purchasing this item from the Black Market and giving it to a Chao will make the wings of a Jewel, Texture or Color Chao the same color as the Chao. Unlike the Dreamcast Wings code, the Cosmetic Wings only change the wings of the Chao you give them to, and not all of them, enabling you to choose which Chao recevies the cosmetic change or not. It can be purchased from the Black Market for 500 rings.

Reverse Mirror

Another new item that debuted in version 9.2. Purchasing this item from the Black Market and giving it to a Chao will invert the chao's colours in a sense. For example, Neutral and Hero Chao become black, while Dark Chao become white. This is an alternative to the older Negative Chao save code; you do not need to hold any buttons for it to occur, it doesn't need to be applied before entering Chao World, and it doesn't apply to all of the Chao. Just the Chao you give the Negative Mirror to, enabling you to choose which Chao recevies the cosmetic change or not. It can be purchased from the Black Market for 2000 rings.

Suspicious Potion

This item debuted in version 9.3, although its function had been in the game before then via an optional code that has now been removed. Giving a Chao this item makes it instantly reincarnate. Baby Chao are not able to use this. It can be purchased from the Black Market for 50000 rings.

CWE suspotion.png

Hero Chao Brush

When this item is given to chao, it will change the palette of the Hero Chao's colours to the skill-type of the brush given to them. For example, a Fly Hero Chao can receive a Run Brush to change the Chao's purple color to a green color, even though they're not a Run-type. Each brush is purchasable from the Black Market for 1000 rings.

Easter Egg Names

The pool of Chao names that the Fortune Teller gives you has been expanded to include some new names.

Move Menu

A feature that debuted in version 9.2. This enables you to transfer your Chao between save files. The menu is able to do its best when the gardens in a save file contain no more than 8 Chao. Otherise, you may notice blank spaces where a Chao of yours should be.

Name Menu

No longer do you need to rely on the Fortune Teller to give your Chao names, and deal with a bunch of dialogue to get there. Version 9.2 features a menu you can find in the Chao transporter that enables you to custom name your Chao right there.


A Lens can be bought for the players chao from the Black Market. It is worn by the chao as they would a hat. Once worn, the chao's eyes will change to that of those on the box. Pictured are the Hero Chao lens and the fanmade Spartoi lens.


Lenses of certain colors can also be obtained, such as the red and green lens below.



Introduced in version 9, accessories are a bonus way you can customize your Chao. Accessories come in a face slot and a head slot. For example, Chao can have a hat and wear glasses at the same time. You can also place an accessory over the hat.

Currently, Chao World Extended has the following accessories included:

Accessory Price
Baseball Cap 2500
Bowtie 2500
Round glasses 2500
Aviators 2500
Headphones 2500
Pacifier 2500
Press hat 2500


Chao world extended also adds the functionality for full-body accessories. The mod includes the following:

Accessory Price
Blue Hoodie 2500
Pink Hoodie 2500
Cheese Bowtie 2500

Customization Menu

Introduced in version 9.1, the Chao transporters in each garden have another function: the ability to customize your Chao's appearance. Here, you can change the hats and/or accessories the Chao can put on, as well as any medals the Chao unlocked from winning Karate matches and Chao Races. Hats and accessories can be combined here.

Shortcut Menu

Version 9.1 has a shortcut menu that allows players to toggle a couple of things. Players can access it by pressing X + Y. The first one is the ability to have the names of your Chao be displayed, similar to Sonic Adventure DX. The second one is a wheel that allow you to change the time of day, assuming you have the Day/Night Cycle feature enabled.

Lifespan Display

As of version 9.1., you can now look at a Chao's remaining life by looking at the Chao's stats tab at the Chao Doctor. You'll also be able to see a Chao's lifespan grade. The higher the grade is, the longer the Chao can live before it dies or reincarnates.

Animal Usage Improvements

A couple of improvements have been made to animal consumption as of version 9.1. There is now an option to make it so animals are reusable. Also, if one hasn't been used yet, you'll see a sparkle effect on the animal.

Oranges & New Animals

Version 9.2 introduced custom animals, and you can get them via oranges. Oranges can be bought at the Black Market for 500 rings. Once you have one, you have 2 choices. You can give it to a Chao for them to eat to increase their Stamina, or you can let the orange sit in your Chao Garden for a bit for it to attract and be eaten by the arrival of 3 custom animals.

Each bite of the orange has a 40% chance of spawning the Fly-type Bee, a 40% chance of spawning the Fly-type Ladybug, and a 20% chance of spawning the Power-type Scorpion. None of them currently have animal behaviors associated with them, but giving them to a Chao can give them related animal parts and 2.5 bars of experience points.


Raising an Omochao is not a new addition to the mod. Prior to version 9.3, it involved giving a Blue and White Robot Texture Chao a red beanie hat. Now, there is an entirely new method of getting one.

To obtain an Omochao, you must have a Chao win the Challenge Race where you race against a bunch of Omochao. The Chao will win a wrench as its prize. The Chao will have the tool to assemble the Omochao, but you'll have to give the Chao the parts. You can do this by giving the Chao multiple boxes of parts, which can be found at the Black Market. Each time you give the Chao a box of parts, it'll slowly assemble the Omochao in the garden, piece by piece. Eventually, when you give the Chao enough boxes of parts, the Omochao will be finished and become the player's newest arrival to their Chao save. Players must keep in mind of the following:

  1. Only the Chao that started building it can finish it.
  2. The Omochao will copy the color of the Chao that is building it.
  3. The Omochao cannot be finished if there's not enough room on the player's Chao save.
  4. If the save is full, Chao cannot build on top of a finished Omochao.

If players do not wish to have an unfinished Omochao in their gardens, they can toggle this option off via the Config button in the Sonic Adventure 2 Mod Manager.

Parent & Grandparent DNA Data

If you'd like to see information on a Chao's parents and grandparents, ala a family tree, you can do so in Chao World Extended. Take a Chao to the Chao Doctor and bring up its health results. When you do, bring up a Chao's stats and grades. Press down to see a screen showing the Chao's parents and grandparents.

More Chao Actions

This code used to be a part of the "More Chao Animations" code prior to version 7.5 of the mod, but became its own code in version 7.5 before being moved to the base mod in version 9.0. As the name implies, enabling this code adds more actions that the Chao can do. For example, if a Chao's hunger value is over 7,500, it can pick a random tree and start shaking it. If some fruits fall down, there's a chance that the Chao will pick up a fruit after the Chao is done shaking the tree. Another added action involves instruments. Chao can also engage in toy bands, similar to the musical instrument bands they could already do in the vanilla game.

If a Chao is playing an instrument, Chao that have at least 4,000 boredom will come over to join the band without the player's help. The piano (Hero Garden) and organ (Dark Garden) garden toys, unused in vanilla Sonic Adventure 2, have been brought in for bored Chao to play as another Chao action, although you will need to unlock them first. This can be done by completing the first levels of the Hero and Dark Races, respectively. The Chao also have a chance of running away in fear if they have bad luck with the jack-in-the-box garden toy. A Chao will also walk while crying or depressed, depending on if the Chao sobbed quietly or cried loudly and with tears.

3 more intruments have been added, the Triangle, Guitar and Accordion. Once a Chao has learned 3 instruments from the Kindergarden, the Chao will then have a chance of playing one of the 3 added instruments instead. Chao can also build sandcastles, if they have the shovel unlocked and are bored enough.

You can also see Chao conversations. Prior to version 9.0, Chao conversations were dependent on the "desire to mate" value and a "Chatty" value. The higher the "Chatty" value was, the less the "desire to mate" requirement was. Once a Chao reached that required "desire to mate" amount, the "Chatty" flag would be enabled, making the Chao available to chat with another Chao that had their own "Chatty" flag enabled. Eventually, these two Chao would meet each other and have a conversation. However, if a Chao was hungry, the Chao would decide to go shake a tree instead. This system received a rework in version 9. Now, Chao just need to have a high Loneliness value.

Chao Relations

Introduced in version 9.0 are more interactions that your Chao can have with each other. As previously stated, Chao can have conversations with each other. You should, however, pay close attention to their body language. Chao conversations can go in any direction. You may notice that some conversations start out with the Chao having a good time and laughing, then suddenly they're getting angry with each other and angrily walk away. Other times, their conversation gets very argumentive, only for them to patch things up at the end. There's conversations that can go positively the entire way, or negatively the entire way. Conversations that are mundane can also happen.

Once the two Chao have talked to each other 5 times, they become friends. Chao that are friends will react to cocoons, if they're close enough to one. Chao will jump for joy if they're seeing a Chao evolve. But, if a Chao reincarnates or passes away, they will mourn for the Chao and cry. However, Chao friends don't stop there. As of version 9.2, Chao that have talked to each other 5 times will unlock a chance that the two Chao friends will gossip to each other. Once they've talked to each other 10 times, they will also be able to either hug each other, or go for a walk and hold hands.

A new event introduced in version 9.2.

By default, assuming that you don't have the Dynamic Lifetime code on, a "Chao day" happens every 2 minutes. Each time this happens, an adult Chao's remaining life ticks down, and the magnitude ticks up. After a certain amount of "Chao days", a "Chao year" occurs where the Chao ages by a year. Taking a Chao to the Chao Doctor, and looking at the Chao's condition will tell you how many more "Chao days" are left before the Chao ages a year. If you just so happen to enter the garden the Chao is in on the same "Chao day" that it ages a year, you've arrived in time to observe the Chao's birthday party event.

During the event, the birthday Chao will have a party hat on its head and is holding a cake. Any Chao that are not sleeping and are close by will come over to the birthday Chao, jump for joy, and eat some cake together. Not only do they eat as if they were very hungry, but eating the cake decreases their Hunger value. The birthday Chao itself will be the last one to eat a piece, once 25 seconds have passed. After the event is done, the Chao must wait another "Chao year" before they host another birthday event, but they can still eat the cakes of other Chao celebrating their birthdays.

Obtainable Character Chao

In vanilla Sonic Adventure 2, the Tails, Knuckles and Amy character Chao were only obtainable through very rare means. The Knuckles and Amy Chao eventually became unobtainable, and the Tails Chao only possible by doing a certain mission in Phantasy Star Online. Chao World Extended adds legitimate in-game methods for getting these Chao.

To do it, follow the method of getting a Chaos Chao. Make the Chao reincarnate twice, give it every type of animal in the game, and increase its Happiness to 80. However, the method deviates from here on. Making the Chao a certain skill-type before it evolves will turn it into a Character Chao, instead of a Chaos Chao. Fly gets you Tails, Run will evolve into an Amy Chao, and Power will net you a Knuckles Chao.

GBA Fruit & SADX Animals

Another feature in Chao World Extended is the addition of the fruit that could be found in the Tiny Chao Garden, seen in the Game Boy Advance Sonic games. Chao can be fed the fruit, but if you leave the fruit lying around in the garden, animals from Sonic Adventure DX will appear.

The animals that show up depend on the fruit. While certain animals will spawn from multiple fruit, there are no animals that spawn from every fruit. It is also worth keeping in mind that the animal spawns are only temporary. As animals spawn, they will "eat the fruit", eventually consuming it entirely. Animal actions associated with these animals have not carried over from Sonic Adventure DX, due to the behaviors either being duplicates, or being turned into classroom Lessons. The only exception is the Lion behavior, an rare action that a Chao will do at random, and without a Lion being necessary. Below are tables of each fruit, along with the pool of animal spawns and their chances of spawning.

Orange Fruit
Otter 35%
Seal 15%
Lion 25%
Gorilla 25%
Blue Fruit
Swallow 40%
Peacock 20%
Parrot 20%

Hyper Fruits & X-Grade

X-Grade is a rank higher than S-Grade that is added by the mod. These are achieved by giving a Chao a "Hyper Fruit", rare items found in the Black Market. There are 4 Hyper Fruits (Fly, Swim, Run and Power) one for each specific stat. Chao can only have 1 stat at a time that is an X-Grade, and only S-Grades can be updated to X-Grades. X-Grades go back to S-Grades when a Chao reincarnates. X-Grade upgrades also need to be done as soon as possible, because X-ranks become pointless the more the Chao has been leveled up. Players will see no significant change if the Chao is level 99 at the time the player upgrades an S-Grade to an X-Grade.

With an X grade and perfect reincarnations (obtaining the maximum level-up points possible for an X grade stat before Reincarnation), the maximum stats are 3560 for Run and 3854 for Swim, Fly, Power and Stamina. Run is slightly weaker as it is considered one of the most influencial stats in the Chao Stadium, especially in Races.

Fruit Rebalancing

The mod also rebalances the fruits. Here's what they now do:

Garden Fruits 40% Stamina (50% if the hard mode code "Hunger is Difficult" is enabled)
Strong Fruit 60% Stamina
Tasty Fruit still gives 30% Stamina but now also gives 60% Luck
Hero/Dark Fruit 50% Stamina and still edits the alignment
Round/Square/Triangle Fruit 80% Stamina
Smart Fruit 30% Stamina and 320% Intel
GBA Fruits give double of what they gave before
Mushroom 160% Stamina
Mushroom Alt 320% Stamina
Mint Candy 200% to Swim, Fly, Run, and Power, but 50% to Stamina

Stat Upgrades At The Health Center

While looking at the chao stats screen at the Health Centre, the player can pay Doctor Chao to upgrade stats in exchange for rings. Keep in mind:

  • The Chao's grades can only be upgraded 3 times per life.
  • The higher the grade, the more rings are required to upgrade it.
  • An A-rank also cannot be upgraded to an S-rank via this method.
  • Your chao must also have reached level 99 in the stat you wish to upgrade.

As for how you upgrade, you look at the Chao's stats at the Chao Doctor, then input the corresponding button combinations to each stat type.

Stat Button Combination
Swim Y + DPad Up
Fly Y + Dpad Down
Power Y + Dpad Right
Run Y + Dpad Left
Stamina Y + L and R
Upgrade Cost
E > D 10,000 Rings
D > C 20,000 Rings
C > B 30,000 Rings
B > A 40,000 Rings


As of version 8.3, Chao World Extended now offers a way for modders to insert custom fruits and hats to the game with more ease than previously.

Disable Level Up Jingle

Mod Name: Disable Level Up Jingle

As the name implies, this will disable the jingle that plays whenever a Chao levels up. This will prevent the music being interrupted and reset back to the beginning when the level up happens.

Chao Party Race Fair Patch

Mod Name: ChaoRacePatch

This mod changes some things in the Chao Races to make things more fair. It gives the player's Chao more of an opportunity catch up if the Chao messes up.

Newer Challenge Race

Mod Name: NewerChallengeRace

Newer Challenge Race is a mod that edits the Challenge Race. It is a challenge directed to users who have finished the original Challenge Race too easy and want more of a challenge. The difficulty starts off at the last difficulty of the originally Challenge Race and gradually gets more difficult.

HD Toys Models

Mod Name: HD Toys Models

This mod, included in version 9.3 of Chao World Extended, replaces the models of the Neutral Garden TV and Dark Garden TV to the model versions seen in SEGA Superstars.


Chao World Extended features many optional codes that the user can enable to enhance their experience with the mod. The codes come in various categories and difficulties, depending on if the player would prefer more of a challenge raising Chao or not. Prior to version 9.3, you could find the codes via the Codes tab of the Sonic Adventure 2 Mod Manager. Now, they can be toggled via the Config button in the Sonic Adventure 2 Mod Manager.

Save Files

These codes tinker with the game's save file system.

Multi Save File

In vanilla Sonic Adventure 2, you can have 10 main game save files, but only one Chao save file is allowed. This code makes very main game save have its own Chao save file. With all 10 Chao saves, you can have up to 240 Chao with the code enabled.


These codes make Chao World more challenging, but not too challenging. Some codes also add new things that Chao can do for those that are really interested in raising Chao.

Monster Evolution

This code, when enabled, gives Chao the ability to take their second evolution to the next level. For a Chao to do this, one of their stats needs to reach 2,000 points. Once the Chao has 2,000 stat points in Fly, Run, Power or Swim, you'll also need to increase the magnitude of that type past its normal maximum level of -1.000 or 1.000, depending on the type. This can be done by contnuing to give the Chao animals and Chaos Drives, even if the Chao is at level 99. Once you achieve this, Chao that have a "normal" color and high enough magnitude in a certain type will become transparent. It can go even further if one of the stats reach 3,000 points. Its transparency in a Level 2 Monster Evolution increases a little more, but the Chao's features, depending on what type it is, will become even more defined.

Chao that don't lean towards being a Fly, Run, Power or Swim type, a Normal Chao, can still achieve a Monster Evolution via a high enough Stamina stat. It enhances a Chao's normal second evolution, but the Chao doesn't become transparent. Chao also don't become transparent if they're not a regular color, even if that Chao is a Fly, Run, Power or Swim type.

Normal Chao Can Make Color Chao

This code gives Chao breeding an extra layer of depth by enabling Chao with normal colors to pass on the color to their children. This includes the transparency effect that Chao with Monster Evolutions experience.

Medal Chao can make Jewel Chao

The vanilla version of Sonic Adventure 2 only allows you to get Jewel Chao by using the Tiny Chao Garden in the Sonic Advance games. However, this code provides players with a new method to do so, as well as another layer of depth for breeding and more incentive to do Chao Races. The code enables medals won from Chao Races to make Jewel Chao.

When a Chao wins a medal, they will wear it on their chest. While that specific medal is worn, there is a 50% chance that the offspring of the Chao that won the medal and another Chao will be a Jewel Chao. What Jewel Chao can hatch depends on the medal the Chao is wearing. If the parents are wearing two different medals, the Jewel Chao can be either of the colors associated with that medal. For example, if one parent Chao is wearing a Hero medal and the their parent Chao is wearing a Silver medal, then the Jewel Chao that has a 50% chance of hatching can be Silver or Gold. The Diamond Medal, when worn, not only makes every type of Jewel Chao possible to hatch from an egg, but it adds the chance of hatching one out of more than 100 of a new type of special Texture Chao. You can see below what Jewel Chao can come from what medal.

Hero Medal Gold
Dark Medal Silver
Aqua or Sapphire Medal Aqua or Sapphire
Topaz Medal Topaz
Peridot or Emerald Medal Peridot Or Emerald
Garnet or Ruby Medal Garnet or Ruby
Onyx or Amethyst Medal Onyx or Amethyst
Pearl Medal Pearl (Have a Chao become friends with a Pearl Chao)
Diamond Medal ANY Jewel Chao, even Texture Chao

There are 2 Chao in particular that you can get via the Texture Chao. In earlier versions of Chao World Extended, the 2 Chao had been secret easter eggs. If you gave a Robot Texture Chao a beanie hat, it would turn into Omochao. However, players needed to keep in mind what the robot and beanie colors were. Blue and White Robot Texture Chao would only turn into Omochao with a red beanie hat, and Yellow and Orange Robot Texture Chao needed a blue beanie hat. The other Chao was a Full-Egg Chao, where they turned into a neutral Chao egg. To accomplish this, you needed to hatch a Chao Egg Texture Chao, then give it an eggshell hat. As of version 9.3, both of these Chao types are still in the mod, but the methods of obtaining them have changed.

Chaos Chao & Character Chao are like Normal Chao

This code, when enabled, gives the immortal Chaos and Character Chao the ability to have animal parts and mate.

Transform PC Shiny Jewels Into GC Shiny Jewels

When this code is enabled, the appearance of Shiny Jewel Chao are changed. You will be able to have Transparent and Invisible Chao by breeding a Shiny colored Chao with a Jewel Chao, just like the Gamecube version. Be careful though. Backup your Chao, because once you've saved, the code can't be undone on your Chao.

Mixing Colors

Enabling this code will add more depth to Chao breeding. You can mix different Chao colors together and achieve entirely new special mixes of color, increasing the variety of Chao that can hatch from eggs. A full list of all the colors can be found in a document that you can see here.

Eye Colors For Newborn Chao

With this code enabled, you can get another way for Chao to have custom eye colors that doesn't involve the lenses. This code gives newborn Chao a chance to be born with different eye colors. However, this will not give a Chao alignment eyes or special eyes. Those can only be done with lenses.

Fruit Can Spoil

You will need to pay extra attention to your fruit with this code enabled, because fruits will occasionally spoil and change color before disappearing. Giving a Chao a Spoiled Fruit will decrease their Magnitude and Stamina. Stamina, however, will not level down.

Create New Shiny Jewel Monotone

This code, when enabled, gives a unique look to newborn Chao that are Shiny Jewel Monotone. It's a mix of Texture and Jewel Chao, but with a Shiny color on it.

Newborn Chao Have Varying Shades Of Color

This code adds more colors that newborn Chao can have. If you purchase multiple Chao of the same color from the Black Market, you can get multiple shades of that color.


These codes also make Chao World more challenging, but as the name implies, it won't be an easy time. These codes are related to a Chao's behavior and your interactions with them, making the player ensure their Chao are taken care of and happy.

Bully Chao

This code adds an uncommon interaction that Chao could have with each other, but you will need the "More Chao Animations" code for this to work.

When any Chao is abused, sick, cyring from hunger, or if they've had to listen to a Chao poorly singing, its Anger value will increase. This will result in a Chao stomping the ground in a angry mood, resulting in the Anger value slowly decreasing. This animation will also increase their Surprise value, creating the chance of a Chao deciding to walk to another Chao and bully them by punching, pushing or kicking them. When a Chao's in a bullying mood, they will develop a mean face, even if the Chao's face is normally not like this, a warning sign to watch your Chao closely. If a Chao has a developed mean face, this does not mean the Chao is guaranteed to bully another Chao. It just means that it's a possibility. The Bully Chao will usually attack a Chao that isn't doing anything. A Chao needs to have an Anger value greater than 80 and a Kindness value of less than 30 for a Chao to potentially become a Bully, and they need to be in the mood for walking around the garden, but not wanting to swim, by having a low Tire value and decent Energy value.

The Chao that is bullied will experience the same effects as a Chao you abused, including a Happiness value decrease, but the Bully Chao will calm down afterwards via a Surprise value decrease, and its mean face will vanish. If a Chao's Kindness value is high enough, there is a small possibility that this Chao will defend other Chao by punching, pushing or kicking the Bully Chao.

Hunger's Difficult

Enabling this code makes a Chao's hunger have another effect. If a Chao becomes hungry, and stays hungry depending long enough, its "Urge To Cry" value will jump up. If the Chao is a baby, the value increases to 120. Adult Chao will see an increase to 80. This will happen with any Chao, as long as it's not sleeping during its starvation, but Chao that have a Crybaby personality only need a small amount of an urge-to-cry value to possibly start crying. Regardless of the Chao's personality and age, once the Chao starts crying, it will lose happiness faster. Meanwhile, the garden's fruit will give Chao more Stamina than usual.

Enable Spin Dash & Somersault

This code allows the player to Spin Dash and Somersault, like in Sonic Adventure DX, in Chao World. Characters like Sonic and Shadow will be able to use more of their moves here, but it increases the risk that you will accidentally hurt your Chao.

More Sick Chao

In vanilla Sonic Adventure 2, it is very unlikely to see a Chao get sick. If you have Chao World Extended and this code is enabled, that will all change. This code encourages players to take good care of their Chao by making the Chao sick if the player does something wrong. Once the Chao Doctor takes care of the sickness, the Chao will not get the sickness again for a long time. However, your Chao will only need 80xp instead of 100xp to level up while it is sick. The sickness will not immediately happen to the Chao after the mistake is made, but will do so later on. It is also not a 100% chance that the Chao will develop the sickness. So, players will need to pay attention to what their Chao are doing. If a Chao is standing around and seems to be not doing anything, there's a chance it's sick. Sick Chao tend to do this more often, because most of their illnesses force them to stand up.

A Chao's personality and skill-type can also make them immune to certain sicknesses. Chao that are Swim-types will not get a Cold or Running Nose. Hiccups, which happen to Chao that eat too many fruit too fast, and Stomach aches, which happen if a Chao has overeaten because the player forced them to eat, won't happen for Chao that are a Power-type. The Chao's personality can also influence what sicknesses the Chao can get. For example, personalities will decide if a Chao gets a Cold or Running nose from swimming too much. If you have a very active Chao, it will likely be the latter. If a Chao has a Big Eater personality, it will not get a Stomachache if the Chao has overeaten because the player forced them to eat.

There are only 2 sickness that can happen to a wide range of Chao. The first is Coughing, which Chao are prone to getting if they're 4 years old and up. The second, a Rash, is alignment-specific. Hero Chao can get rashes if they are taken care of by a Dark character, or they're living in the Dark Garden. The same applies vice versa. If a Dark Chao lives in a Hero Garden, or they're being taken care of by a Hero character, they'll develop a Rash. However, the garden seems to take priority above all else. Even if a Chao is being taken care of by a character of the opposite alignment, they won't develop a Rash as easily if they're in the correct garden alignment. Regardless of the sickness, and regardless of how high the Chao's Happiness value is, the Chao will lose 30 happiness and is guaranteed to not reincarnate if it is sick.

Chao Attention

This code adds more depth to Chao behavior and evolutions. If you're not petting your Chao often or giving it some attention, its Happiness value will slowly decrease. However, they will also evolve faster.

Annoying Mean Chao

New to version 9.3, this code makes Chao with angry eyes gradually hate all characters. This can be particularly concerning if you have Bully Chao enabled.

Easy & Peaceful

These codes are the least challenging of the bunch. If you'd rather raise Chao more casually with less stress, or if you want certain things to go more smoothly with less effort required on your end, then enabling these codes will help.

Fruits Never Disappear

This code makes fruits unable to de-spawn, including fruits you have purchased from the Black Market.

Reusable Chaos Drives

As the name implies, this makes it so Chaos Drives don't disappear after you give it to a Chao. They will remain reusab;e

Instantly Grow Trees

This code, also as the name implies, makes it so trees reach their full growth immediately after their seeds are planted.

Instantly Grow Fruits

Do you have so many Chao in your garden that there's not enough fruit for them? Then this code is going to help. As long as your fruit inventory doesn't get filled up because of fruits from another garden you're not in, fruits ill instantly grow to full bloom on the trees and quickly fall off. The cycle repeats once the Chao eat the fruit, meaning that your garden is always going to have some fruit available for your Chao.

Reincarnation Requires 20 Happiness

When enabled, the code makes the required amount of Happiness for a Chao to reincarnate to be 20 instead of 80. The code also makes a Chao grow up at a slower pace, and the speed of the garden cannot be changed to be faster using a chao editor.

Stronger Chaos Drives

Having this code enabled will make Chaos Drives stronger and provide Chao a lot of points. The catch is that they won't give any Luck.

Chao Can't Hate Any Character

If you have this code enabled, then the character bond values for Chao will never drop below 0. This makes it impossible for a Chao to dislike characters.


These codes do not change the difficulty of Chao World at all, but they do add things that may make things more fun or helpful for players.

Dynamic Lifetime

If you have this code enabled, the length of a Chao's life will change, depending on the amount of Chao that are in the garden at once. If it's less than 8 Chao in a garden, Chao will grow and evolve faster. If it's more than 8, they'll grow and evolve more slowly.

Lucky Chao

This code, when enabled, adds a 1 in 60 chance that a Chao will be born with a hat, toy, or lesson.

Stay Baby Chao Until All Level 10

While this code will make getting a Perfect Chao more difficult, it also increases a Chao's stats very slowly until they reach level 10. It will also be unable to evolve until either The Chao will gain enough points from this code to be able to walk and swim on their own time, but you'll need to give them another 100 Fly stats points for them to be able to fly.

Merge Hero and Dark Garden Chao Slots

In vanilla Sonic Adventure 2, the Hero and Dark Garden have 8 Chao slots each, and they are completely separated from each other. This code changes that. Enabling the code will merge the Chao slots of both gardens. For example, if the player has 1 Chao in the Dark Garden and 1 Chao in the Hero Garden, they can find both of their Chao in either garden. Merging Chao slots is currently not possible for the Chao Garden, as the garden's coding is different in that regard.

Increase Chao Limit Per Garden To 16

This is another code that changes the Chao limits in gardens. Enabling this code raises the maximum amount of Chao that the player can have in any garden to 16. It is currently not possible to have more than 24 Chao in a save file, but this code is not needed to merge the Chao slots of the Hero and Dark gardens.

Remove Breeding Limit

Prior to version 9.3, this had been a feature in the main mod. It is now an optional code. The code makes Chao still able to breed if there are 8 or more Chao in the garden. If you do not have any other mods that change this limit, the code disables breeding once you have 24 Chao in the save file.

Triple The Personalities Effects

All Chao's personality gets amplified by 3, making them do more things and increase activity in the garden.

No Animal Parts

There are 2 codes in Chao World Extended that, depending on which one you go with, will automatically remove a specific number of animal parts. The first one will remove only the animal parts for arms and legs. The second one removes all of them.

SADX Chao Alignment

In Sonic Adventure 2, players were given a different method to turn a Chao into a Dark Chao or Hero Chao by leaving it up to what character takes care of a Chao and how well they treat them. This code removes that entirely, forcing the player to use the Sonic Adventure DX method of Chao alignment: giving a Chao a Hero or Dark fruit.

More Chao Face

This code increases the variety of faces a Chao can have when it hatches out of an egg. Some examples include a happy face with an open mouth. Some faces can now make the Chao look like they are sleeping, not amused, or even screaming. If a Chao has a screaming mouth, some players that have played Chao World Extended have decided to call them a "Screamer Chao". The "Fitting Chao Personality" code will adjust accordingly if this code is enabled.

Remove Dark Chao's Mean Eyes Override

When a Chao evolves into a Dark Chao in vanilla Sonic Adventure 2, they are always forced to have mean eyes. If enabled, This code stops that, allowing the Chao to keep the eyes it had before it evolved.

Chao Counter

This is a code that, when enabled, makes it easier to keep track of the amount of Chao in a garden. Pressing the Start button will bring up a counter that can be seen at the bottom of the screen. The counter is a series of Chao symbol icons, and every icon represents a Chao the player has in the garden. Depending on other codes enabled in the mod, the counter can display up to 8 or 16 Chao.

Always Baby Chao

If this code gets enabled, a Chao's evolution will not happen until the Chao reaches level 99 in Stamina, or level 10 in all stats. Disabling the code will also let the Chao evolve. This can potentially make a Chao's life last longer.

Shorten Black Market Dialog

This code, added in version 9.4, is precisely what the name implies. Enabling the code allows players to see what is in stock in the Black Market quicker, and you're able to bypass the dialog you see when you enter the Black Market.


These codes enable features you can enable based on your preference of controls, or something you can enable by doing certain key/button inputs.

Better Camera

The game's camera will be more controllable with this code enabled. Players can rotate the camera up and down by using the Right Stick, and move it up and down by using the D-Pad Up and Down. Freezing the camera is possible by hitting the left button on the D-Pad. Unzoom Mode can be activate with the right button on the D-Pad, and when the player is all done, pressing the L and R shoulder buttons together will reset the camera back to normal.

Zoom Camera Without Numpad

The game's camera will be more controllable with this code enabled. Players can move the camera up and down by using the "R" key and "F" key, respectively. and rotate it up and down by using the "T" and "G" keys, respectively. Freezing the camera is possible by hitting the "*" key. Unzooming the camera can be done with the "-" key. If you want to get more of a zoom, press the "+" key. When the player is all done, pressing the "backspace" key will reset the camera back to normal.

Hold X To Go Negative Chao Save

This code comes from an old mod that is now part of Chao World Extended. Once the code is enabled, hold the X button on your controller, or the U key on your keyboard, before entering Chao World. Doing so will make the game create a new save file (SONIC2B__BLK) with alternate Chao skins. Neutral and Hero Chao become black, while Dark Chao become white.


These codes mostly make the Chao more lively than ever. The Chao will be more expressive, make more sounds, do more things and have personalities that stand out more.

Fitting Chao Personality

This code, when enabled, revamps the personalities of Chao. A Chao's personality will be set depending on the Chao's face. For example, if a Chao's expression is sad, then that Chao will likely have a Crybaby personality. Chao that have wide open mouths may be Big Eaters. If the Chao has a "> <" face, they may be Energetic, depending on the mouth they get with it. The personality can also change with evolutions. A Power-type will become a Big Eater, while Run-types go the opposite way. Likewise, Fly-types become more Curious with their personalities, and go the opposite way if they become a Swim-type. Chao will also gradually come to dislike characters of the opposite alignment.

The effects of personalities are also multiplied by 4, making them stand out more. Here's what Chao personalities and related values do what in Chao World Extended:

  • Energetic Chao will move around the garden more, and they also swim more often. Their animations are faster, will hate you faster if abused, and they may go to a tree to take their nap when they're sleepy.
  • Big Eater Chao will eat a lot. They will always eat like they are starving, and will punch their food on occasion.
  • Crybaby Chao will cry more often when it is abused or hungry, and sit around the garden more. When they start crying, it takes them longer than other Chao to calm down.
  • Carefree Chao won't be bored as easily, take longer to hate you if they're abused, and their animations are slower.
  • Naive Chao will take less time to become sleepy, and their naps will be longer.
  • Curious Chao will get bored more often. They're also less likely to throw their food away.
  • Skillful Chao will pick up Chaos Drives and Animals faster.
  • A Chao with high Solitude won't interact with the character much, such as greeting the character and wanting the character's attention.
  • Kind Chao won't become Bully Chao as easily. In fact, they have a chance to interfere with a Bully Chao's attack.
  • A Chao with high Regain will recover from dizziness faster, wake up faster, and stand up from sitting and doing nothing faster.
  • Chatty Chao, prior to version 9, will talk to other Chao more often (if "More Chao Actions" and "More Chao Animations" are enabled).
  • A Chao with high Vitality moves around the garden more, and enters its mating season faster. A Tire value exists that acts as a check on Vitality so the Chao doesn't overdo it, especially with Energetic Chao.

Fickle, Charm, Stress and Condition are not used in Chao World Extended, because these have been hidden values in the game that were discovered only recently. Stress seems to make a Chao pass away without reincarnating, and Condition seems to be related to sicknesses. Fickle is used to calculate Chao emotions such as Relax, which is a timer that decides how long a Chao stands still after being pet them or put them down.

More Chao Animations

This code is a big one. It brings back many Chao animations that were not used in vanilla Sonic Adventure 2, but had been buried inside the game's coding. Below is a table of every animation Chao World Extended brings back, as well as what makes them happen.

Animation Cause of Occurrence
  • 4 - think (animated)
An alternative animation for Chao that are thinking on what to do, happens randomly.
  • 8 - toe tapping to hand behind
  • 9 - hand behind
These are two idle animations Chao will do based on their alignment. Dark Chao do #8 and Hero Chao do #9. For the latter, the Hero Chao looks down at the ground bashfully.

  • 80 - Alt Sit Down
A random animation that triggers when a Chao goes to sit.
  • 83 - look closely ?
An idle animation that happens randomly.
  • 104 - discreetly walk
This animation can randomly happen for 2 reasons. The first one is if the "Day/Night Cycle" garden feature is enabled. Chao are coded to sleep at night with this on, so the Chao might do this animation if they are trying to get a fruit at night without waking the other Chao. The other time this can happen is related to a Chao's mating season. Chao that are not in a Chao's circle of flowers, but wish to mate with them, will do this.
  • 105 - sad walk
Happens after a Chao finishes sobbing quietly to itself while standing up.
  • 107 - Start Running into something with arms Up
  • 108 - Running into something with arms Up without stop
Alternate running animations that happen randomly, but especially when they have fear, are chasing the ball, or get called by the player. It's more likely to see this if the Chao has a high amount of run skill points.
  • 121 - Chao mate walk 2
Another Chao animation that can happen if the Chao is in range of a Chao in mating season, but they're not within the Chao's circle of flowers.
  • 122 - Start brake
  • 123 - braking
Similar to Sonic's brake, this happens randomly after a Chao stops running.
  • 127 - Start dizzy walk
  • 128 - Dizzy Walk
If a Chao's dizziness value is high enough, the Chao will do this, even if they're wanting to swim. They will just do this on their way to the water.
  • 131 - Start fly and success
  • 132 - Start fly and... (see 133)
  • 133 - Can't fly
In Chao World Extended, Chao do not need a cliff to fly, and will do these animations anywhere. 132 and 133 will happen if a Chao has less than 100 Fly stat points.
  • 135 - Start to Jump
  • 136 - Jump
Alternative jump animations that happens randomly if a Chao is coming down from the ruin of the Hero Garden or the rocks of the Chao Garden.
  • 143 - super swim with head underwater
  • 144 - move the head up and down while super swim

143 and 144 happens if a Chao has over 700 Swim points, jumps into the pool, and starts swimming with their head underwater. 149 happens randomly if a Chao's eyes go "> <" and their Swim stat points are under 700.
  • 151 - drowned
Happens if a Chao has 0 Happiness and can't swim while in the pool with the "Chao Drowning" code on.
  • 156 - Climb finish
  • 157 - Difficult Climb
In Chao World Extended, climbing zones are added in the gardens for Chao to climb on. 156 happens on a climb that occurs with or without any problems. 157 will happen if the Chao has under 150 Power stat points, meaning that there's a chance they don't make it to the top of the climbing area.

  • 165 - touch his stomach while sit down (slow motion)
  • 166 - touch his stomach while sit down (normal speed, animated)
  • 167 - touch his stomach while sit down (stay still)
This happens after a Chao finishes eating. How hungry they still are after eating will determine which animation they do. If their hunger value is over 5,000, they will touch it only once, meaning 164 and 165 happens. If they're full, they'll rub their stomach and 166 and 167 happens.
  • 178 - spit while eating
Happens randomly while a Chao eats a fruit, implying that they ate a seed and are spitting it out. Big Eater Chao tend to do this more often.
  • 187 - sniff something
If a Chao is hungry enough and goes to eat a fruit on the ground, there is a 50% chance that they do this animation before picking up the fruit.

More Chao Sound

This code, when enabled, allows Chao to make more sounds. Some sounds were unused in vanilla Sonic Adventure 2, while others were brought in from Sonic Adventure DX. If the code is disabled, the Chao will revert to the sounds they can only make in vanilla Sonic Adventure 2. With the code on, Chao will make sounds when they pick up a fruit, are thrown, jump off of a high platform, the player gives them a fruit, the Chao finishes eating, a dream or nightmare during sleep, and much more.

Doctor Chao Give More Information

More Face Expression

Chao will gain more facial expressions with this code enabled. Depending on the action, there are some Chao actions that Chao will now change expressions for. For example, Chao will have a happy face after they are done eating a fruit.


These codes enhance Chao Races, mainly by adding new features.

Chao Karate Give Medal

Enabling this code will add 4 medals that Chao can win by becoming the champion in each tournament. The Beginner tournament gives an Amethyst Medal, Standard rewards your Chao with a Ruby Medal, Expert gives a Sapphire Medal, and the Super tournament gives your Chao an Emerald Medal.

Jewel & Beginner Race Becomes 8 Chao Party Race

Although this code is made for Chao Races Tournaments, and using it requires Fusion's Chao Editor, it is still one players can enable. Doing the 8 Chao Party Race, however, is relatively simple. Players have to select Jewel race, a random Chao, then a race. When a race starts, the first 8 Chao slots you have will be who competes in the race. You can see who they are in the top of the "Your Chao" area of the Chao Editor.

Manually Switch Camera (Using Keyboard)

In vanilla Sonic Adventure 2, and with this code not enabled, the camera will only follow your Chao during Chao Races. Enabling this codes adds the ability to use the number keys, from 1 to 8, to have the camera switch the Chao it is focused on.

Win Jewel Chao In Jewel Race

This is another method for players to get Jewel Chao. This time, the chance is 100%. The code, when enabled, allows players to win a certain Jewel Chao on the 5th level of a race, as long as the player does not already have that kind of Jewel Chao in a garden, or they have 24 Chao in their save file. For example, winning the 5th level of the Garnet Race will reward players with a Chao egg that will hatch into a Garnet Jewel Chao. If you already have a Gernet Chao, or you have reached the 24-Chao limit allowed in a save file, you will not receive an egg.

Chao Gain Experience Points By Doing Races

Enabling this code will let Chao gain some experience points for each second the Chao spends in a Beginner and/or Jewel race. When the Chao finishes the race, the number of experience points gained will be added to their stats for leveling up. Passing 100 experience points will add 1 level, and passing 200 experience points will add 2 levels. The amount the Chao receives also depends on the Chao's grade level. For example, if the level up is for a stat type that is S-ranked, the Chao will receive 30 skill points, just like it does from giving Chaos Drives and Animals.

Each race levels up different stats. Aquamarine focuses on Swim, Topaz focuses on Fly, Peridot focuses on Run and Garnet focuses on power. Onyx and Diamond focuses on all of the skill types, but they increase more slowly. Also, all of the races will increase Stamina. However, compared to other stats, this will also increase more slowly. This code only works for Beginner and Jewel Races.

Cheat & Debug Codes

These codes contain things used for technical or cheat/anti-cheat features. If you want your Chao to become very overpowered, these codes will achieve that goal. However, there will be some Race codes, modded Chao Races, and Chao Race tournaments held by the community that your Chao will be banned from.

Black Market Debug Menu

Enabling this code gives you the ablity to activate the Debug Menu when you're in the Black Market. To activate it, use the X and Y buttons on your controller, or the Yellow and Blue inputs you have mapped to your keyboard. A menu will appear in the top left that enables you to make any item, no matter how rare it is, become available to purchase for its usual price via the Black Market.

If you want your Chao to become very overpowered, these codes will achieve that goal. However, there will be some Race codes, modded Chao Races, and Chao Race tournaments held by the community that your Chao will be banned from.

More than 99 Levels

Vanilla Sonic Adventure 2 have a Chao level limit of 99. This code removes that.

Nerf Cheated Chao Stats

This code edits a Chao's stats to be more legitimate, especially if you have edited stats created from Chao editors or you used the Level 99 limit removal code. If the player would like their overpowered, hacked Chao to be able enter the game's Chao Races without the Chao being pushed to another garden, then this codes will help.

Removed Codes

These codes had been in the mod at one point, but for varying reasons, eventually got removed.

Chaos Chao Keep Eyes Upon Reincarnation

Enabling this code will allow Chaos Chao to keep their eyes if they reincarnate.

As of version 9.3, this code has been removed due to players not using it.

Pacifier Reincarnates Chao

Giving a Chao a Pacifier item with this code enabled will make your Chao reincarnate immediately. However, its stats will be divided by 20 instead of 10. Depending on the skill type that the Chao had when it evolved, that skill type's rank will decrease by 2. For example, if the Chao is a Swim Type, their Swim Rank will go down by 2. Depending on how strong the rank is, the Chao's grade of Intelligence and Luck will be increase. The higher the Chao's skill type rank is, the larger that the increase to the Intelligence and Luck grade will be.

In version 9.3, the pacifier became an accessory, and the pacifier's old function was used for the Reincarnation Potion that can be found in the Black Market. Because of this, the code has been removed.

Chao Can Drown

When this code is enabled, Chao that can't swim are at risk of losing their lives to drowning. Chao that cannot swim will not be interested in going into any water, with the only exception to this being the water found in the Hero Garden. However, entering any garden will spawn Chao in places that force them to jump into water to get to the garden's mainland. If this happens, you will need to get the Chao out of the water as soon as possible, especially if it is a newborn Chao.

If a Chao cannot swim and jumps into the water, it will flail as usual. Its Happiness value will slowly decrease the longer the Chao is in the water. If the value reaches 0, the Chao will become motionless in the water and a gray cocoon will appear. If you are fast enough, entering and exiting the garden will save the Chao's life. If not, the Chao will pass away and be lost.

The code got removed in version 9.3 due to it not playing well.

DC Wings

The original Sonic Adventure 2 on the Dreamcast had the ability to make the wings of a Jewel, Texture or Color Chao the same color as the Chao. Enabling this code brings that back to the PC version.

In version 9.2, this got changed to be the Cosmetic Wings item that you can give a specific Chao by buying from the Black Market. Because of this, the code has been removed.

Use Number Pad / Dpad For Change Items In Black Market

This code will give players the opportunity to change items in the Black Market with the 1 2, 3 and 4 Number keys, or using the D-pad if using a controller. 4 pages will be available, each containing fruits, eggs, hats, and more. However, rarer items, for balancing reasons, will not appear at all. These items will only appear as a random occurrence with the code disabled.

This code has been removed in version 9.3, because the Black Market Debug Menu code had been added, making this code pointless and not needed.

Monster magnitude evolution

This code has been removed for version 9.3.
