Hacking
There are many things that can be accomplished through hacking in the Tiny Chao Garden, such as editing a Chao’s stats, or getting unique and otherwise unobtainable kinds of Chao! It is one of the easiest ways to hack Chao, because Game Boy Advance save files can be transferred to the PC with cheap devices like the GameShark. You can then edit the save files on your PC, transfer them back to the GBA, and then transfer your hacked Chao to the GameCube!
