Main Package

Chao World Extended is a collection of mods for use with Sonic Adventure 2 for PC. They are loaded into the game via a program called SA2 ModLoader.

Alongside these mods, included are Codes that can change various functions.
Mods edit the garden texture, and the style of the game you choose. Codes exist to edit the Chao and Chao World behaviour itself.

The Chao World Extended Mod is the main mod, enable this or your game will crash!

Once enabled, move this mod to the top of the list in the SA2 Mod Loader for other mods to work best with it. Please note that when you tick the box to activate it, there will be a slight lag while it registers!

  • New Chao Colours
    Thanks to Mindacos, all new Chao Colours have there own unique Shiny Jewel Colours too!

  • Character Chao Obtainable
    To get Character Chao, just do the same method you would use to get a Chaos Chao, but instead of keeping it neutral stat alignment, evolve it to a specific type to make it evolve into a Character Chao instead!
    All SA2 animals + 2 Reincarnation + 80 Happiness + Fly = Tails Chao
    All SA2 animals + 2 Reincarnation + 80 Happiness + Run = Amy Chao
    All SA2 animals + 2 Reincarnation + 80 Happiness + Power = Knuckles Chao

  • New Items: Chao Garden Piano and Organ
    Add the unused Sonic Team piano in the Hero Garden and the organ in the Dark Garden! If you don’t want these toys, you can disable them by selecting ChaoWorldExtended then click Config with SA2Modloader

  • New Items: Lens Box

  • New Items: Shiny Fruit
    Using the Brightfix mod made by Exant (included in CWE.dll), using the Shiny Fruit allows you to change any of your Bright Chao into a true Shiny Two-tone Chao!

  • New Items: Hyper Fruit
    This new fruit is rare and can be only found in the Black Market without using the D-Pad code. They are powerful and can be used to upgrade a Chao’s S Grade stat to the new and powerful grade, The X Grade. You will need the correct type fruit for the stat you want to increase. There are Hyper fruits for Swim, Fly, Run and Power.

  • The X Grade
    Unlike other grades, it is temporary, and only one stat at a time can be at a grade of X. The X-graded stat has a massively-boosted stat cap until the Chao reincarnates, after which the grade reverts to S. Note that since the stat cap is what is affected, it is wise to upgrade the S to the X Grade before the respective stat is at Lvl 99.

  • New Grade Increase Method
    Tired of making your Chao reincarnate over and over to increase its grades? No worries - the Chao Doctor will help you boost your Chao’s grades! This requires rings, and the stat must be at Lvl 99! Your Chao’s grades can only be upgraded 3 times per life — from E to A — and the higher the grade, the more rings that are required:
    E > D = 10 000 rings
    D > C = 20 000 rings
    C > B = 30 000 rings
    B > A = 40 000 rings
    To upgrade, input the following while looking at your Chao’s stat table:
    Y + DPad Up for Swim
    Y + Dpad Down for Fly
    Y + Dpad Right for Power
    Y + Dpad Left for Run
    Y + L and R for Stamina

  • SADX Animals
    SADX Animals are obtained differently from SA2 animals. They are somehow interested in those GBA fruits around your gardens: If you buy GBA fruits from the Black Market and leave them in the garden, a SADX animal may appear!
    NOTE: each GBA fruit gives a different kind of SADX animal

The Codes are split into a variety of groups, which are all listed below.



Advanced Codes edit the system and unlock Chao you cannot obtain through normal means.


ATTENTION: After you enable this, there’s no way to go back except backing up your save files or using a Chao Editor… Think about what you’re doing before you enable one of them!

  • Easy GC Shiny Jewels
    This code changes the appearance of Shiny Jewel Chao to the Gamecube version! THis means you can have transparent Chao and invisible Chao when you brain Shiny Coloured Chao + Jewel Chao - see this page for more details.

  • Chaos and Characters Chao are like Normal Chao
    With this code, your Chaos Chao and Character Chao (Tails, Knuckles & Amy) can gain animal parts and mate with other chao, while still being immortal!

  • Chaos Chao Keep Eyes Upon Reincarnation
    test test test test test test test test test test test test test test test test test test test test test test test test

  • Dynamic Lifetime
    This code edits chao lifetime depending on how many chao is in the garden at once. If you have less than 8 chao in the garden, the chao will grow and evolve FASTER. If you have more than 8 in the garden, the chao will grow and evolve SLOWER.

  • Medal Chao can make Jewel Chao
    For example: When your Chao is wearing a jewel medal like topaz, it could make a Topaz Chao which breeding! (Works 50% of the time.)

Hero medal: Chance to make a Gold Chao
Dark medal: Chance to make a Silver Chao
Aqua or Sapphire medal: Chance to make an Aqua Jewel chao or Sapphire Jewel Chao
Topaz Medal: Chance to make a Topaz Chao
Peridot or Emerald medal: Chance to make a Peridot Jewel chao or an Emerald Jewel Chao
Garnet or Ruby medal: Chance to make a Garnet Jewel chao or Ruby Jewel Chao
Onyx or Amethyst medal: Chance to make an Onyx Jewel chao or Amethyst Jewel Chao
Pearl medal: Chance to make a Pearl Chao
Diamond Medal: Chance to make ANY Jewel Chao, even a Texture Chao!

  • Create NEW Shiny Jewel Monotone
    When this code is on, all newborn Chao that are Shiny Jewel Monotone will have a unique look that is basically a mix of Texture/Jewel Chao with Shiny color on it!

  • Mixing Colors
    With this code you can mix different chao colors together and breed entirely new special mixes of color which makes an amazing variety of all new chao! Here’s a List of Mixed Color chao made by Mindacos.

  • Newborn Chao Have Varying Shades of Color
    If this code is on, buying multiple Chao of the same color from the Black Market can give you different results: for example, you may buy 2 pink eggs and each one hatches with a different shade of pink, making them unique!

  • Normal Chao can make Color Chao
    The Regular Chao colours becomes the colour of their evolution. For example, a Swim Chao would be a Yellow Chao, a Run Chao would be Green, etc. This means they can make baby Chao with that colour.

  • Eye Colors for Newborn Chao
    Lenses are not the only way to get Chao with custom eye colors! With this code on, your newborn Chao have a chance to be born with different eye colors! Note that this only applies to eye color: you cannot get alignment eyes or special eyes this way

  • Enable Monster Evolution
    When one of your Chao’s stats reaches 2000 (even more if 3000!), you can help the Chao increase it’s advanced Evolution even further than it’s supposed to through normal means. Please note that chao with the “Regular” colour will become TRANSPARENT when they start to go beyond! The exception to this is if the Stamina stat is taken beyond - this doesn’t make the “Regular” colour transparent.

  • Use Pacifier to Force Reincarnation
    Giving a pacifier will reincarnate your chao back to being a baby, but divide your chao stats by 20 instead of 10. it also downgrade your chao rank by 2 depending his Evolution (if the chao is Swim Type, his Swim Rank will go down by 2)
    However, depending how strong the rank is, it will increase the grade of intel and luck, the higher is your chao rank, the bigger it increase intelligence/luck’s Grade

  • Fruit can Spoilt
    Fruits will now Spoil sometimes before they disappear, they have different color than the original, giving a spoil fruit to your chao not only decrease there stamina (can’t level down though), but also decrease there magnitude


These CODES are dangerous! We recommend you DO NOT enable these codes if you don’t want to risk having your chao die or just leave the game on casually. For those of you who raise chao seriously, this is a little challenge for you. Beware of your chao!

  • Bully Chao (Requires More Chao Animations)
    This code will allow chao attack OTHER chao if they are angry. If the chao gets hit by another chao, it will lose happiness, so pay attention! Luckily, this code will also make happy chao defending other chao, if an angry chao decides to attack, there is a chance that a another chao will stop it! (You must have the more animation code for this code to work properly).

  • Chao can Drown
    If your chao doesn’t know how to swim and goes in the water, it will start losing happiness very slowly, BUT if its happiness reaches 0, the chao will… drown, and a gray cocoon will appear identifying that your chao is on the verge of death by the time the cocoon is gone. Not to worry though, you can still save them by entering/exiting the garden! (classic :blink:)

  • Enable SpinDash and Somersault
    The title says it all, like SADX, you can use the SpinDash or Somersault. You can do cool tricks in the garden but be careful that you don’t hit your chao by accident!


  • Chao Hunger
    When your chao is hungry, it will cry and lose happiness faster. However, it make Garden fruit give more Stamina than usual!

  • Chao Attention
    If you don’t pay attention to your chao or pet it often, it will start to lose happiness. However, they evolve Faster

  • More Chao Sickness
    This code makes your chao sick when you’re doing something wrong,. Notice that when a chao is sick, no matter what the happiness value is, it will be a gray cocoon when it’s time has come (the cocoon of death). However, Your chao will only need 80exp instead of 100 to level up when he’s sick!


If you want play Chao Garden peacefully and at ease without danger or something annoying you, these are the codes for you.

  • Fruits Never Despawn
    The will fruits never disappear. For example, you can buy two heart fruits and use it later without it disappearing.

  • Chao can’t hate Characters
    Once again, the name says it all, chao can’t hate you even if you abuse them, but that doesn’t mean they will always love you necessarily, you will be just neutral unless you take good care of them.


  • Auto Generate Stats
    The stats will now increase very slowly until level 10. Note: This is not a good way to get a Perfect Chao. Link to stats page

  • Stronger Chaos Drive
    Chaos Drives are now stronger than before and give alot of points required! However they not longer give luck

  • Reincarnation Requires 20 Happiness
    This code was previously named “Chao Never Die”, but has been remade to have the Chao require only 20 happiness to reincarnate. Additionally, while the code is on, Chao will grow up a little more slowly


Here are some codes that can add fun to the game, or be helpful towards you!

  • Chao Counter
    This code will count how many chao you have in the garden, the counter is shown when you press start so it will be easy to count chao especially if your chao aren’t mating and you can’t figure out why.

  • Chao Karate give Medal
    When your chao wins all 5 rounds in Chao Karate, it will win a new medal strictly available to Chao Karate only!

  • Lucky Chao
    There’s 160 chance that a chao can be born with a hat, toy or lesson!

  • Always Baby Chao (Until all lvl.10) by ChaoGardenBuster
    Baby Chao will never evolve until you disable the code or the baby reaches level 10 in all stats (or stamina reaches level 99). You could probably make a chao live longer.

  • Merge Hero and Dark Garden Chao Slots
    The chao that are in hero or dark garden will move to one garden (hero or dark) depending where you are.

The cheat codes make your chao OP, but that will block your chao to access to official Chao Race tournaments and some other Race Codes.

  • Disable Level Limit
    This code removes the level 99 limit.

Anti Cheat

Your chao is hacked and not allowed to the race? No problem, this code will save you.

  • Nerf Cheated Chao Stats
    This code will edit the chao stats and make them “legit” as possible if you used a cheat code (disable level limit) or edited stats with Fusion’s Chao Editor. This will be helpful for some future mods/events that ban hacked chao.


These other codes just edit some other stuff.

  • Disable Animal Parts (Arms + legs)
    This code automatically “removes” the animal parts on a chao’s arms/legs.

  • Disable Animal Parts (ALL)
    This automatically “removes” ALL animal parts.

  • SADX Chao Alignment
    Hero and Dark characters can’t make baby chao hero/dark chao anymore, just like SADX the only way to make baby chao hero or dark is by using hero or dark fruit.

  • More and Random Chao Face
    You can get more chao faces from hatching an egg like happy eyes with an open mouth.

  • Remove Dark Chao’s Mean Eyes Override
    The title says it all: evolving your Chao into the Dark alignment no longer forces it to have mean eyes, allowing your Dark Chao to keep its previous eyes. It’s weird at first, but you get used to it

  • DC Wings by Exant
    Jewel/Texture and Color now infect the wings like they do in SA2DC


  • Jewel and Beginner Race become 8P Party Race
    This code is actually made for Chao Race Tournaments. It actually requires Fusion’s Chao Editor to use it. All you have to do is select jewel race, a random chao, and a race.
    When the race starts you will see the first 8 slots of your chao in the race.
    The 8 chao are selected here:

  • Camera switch Manually (using keyboard)
    use the Number key to switch chao view during the chao race, from number 1 to 8

  • Win Jewel Chao in Jewel Race
    Another way to get jewel chao, a 100% chance this time!


The Save file codes will allow to switch save files in-game and allows you to have as many Chao Garden save files you want.

  • Multi Savefile
    This will make the game use a different Chao save file for each main save file that is present. The game allows you to create a maximum of 10 main save files, which means you can get 10 different Chao save files in total - which is 240 Chao! That’s a lot!

  • Hold X to Load Negative Chao Save
    This code is… kinda special, remember the old mod called “Black Chao Mode”? No? Hmm you’re new to this aren’t you?

Well, that mod became a code. To use it, all you have to do is hold X (U for keyboard) before you enter the Chao World. The game will create a new save (SONIC2B__BLK) and will load an alternate Chao skin (neutral and hero chao will become black, dark Chao will become white).


It’s nice to have more detail too.

  • Fitting Personality
    The personality will be given depending the chao face, color, and evolution. The effect of personalities is multiplied by 4, making the personalities drastically different for each Chao

  • Doctor Chao give more Information (EN)
    This code will make the doctor say other things to your chao instead of the generic “This chao is very healthy, please take good care of your chao”.
    Some of them are really helpful, for example,the doctor can say if your chao is lucky or smart (or both)!

  • More Chao Animation
    The chao will use different animations/actions that you’ve never seen before! Also changes the animation speed of your chao depending of his Personalities

  • More Face Expression
    Added more facial expressions to Chao, and a Chao’s expression may change depending on its current action

  • More Chao Action
    This code simply gives more action to the chao such as:

    • Chao talk each other (this action has been updated, now some chao wave after they’re done talking, and both have collision which means you can’t walk through them anymore!)
    • Shake trees
    • Join Chao while they play instruments

    Almost all the unused sounds will be used in the game.
