You can use a gamecube action replay or a gameshark :)
there isn't a sa2b for PC unless u download a gamecube emulator and the ROM
Its a hack or a cheat that lets you.
Get gecko for gamecube.
SA2 is for the Dreamcast, while SA2B is for the GameCube. SA2 has Big cameos in the level, SA2B does not.(SA2B only has cut scene cameos but so does SA2.) SA2B has more 2 player stages than SA2. SA2 allows you to put your chao in the VMU, SA2B allows you to put your chao in the Tiny Chao Garden. SA2B has Chao Karate. some chao world structure is different.(dark garden is TOTALLY different.) There are more.
Well Gamecube action replays aren't sold anymore but you can probably get one from eBay for around $20
no.
You don't need to hack to use the GameCube controller. The GameCube controller is one of the possible control options for the game.
If you mean Sonic Adventure 2 Battle played on the Wii then yeah of course. I only use SA2B on my Wii cause I don't have a Gamecube.
After your chao has reincarnated twice or more, give it EVERY ANIMAL IN THE GAME and NO CHAOS DRIVES. All of the animals are:PenguinOtterSealPeacockCondor (SA2B only)ParrotSwallow (SADX only)Boar (SA2B only)Rabbit Deer (SADX only)Kangaroo (SADX only)Cheetah (SA2B only)Tiger (SA2B only)GorillaElephant (SADX only)Lion (SADX only)Bear (SA2B only)SkunkMole (SADX only)Koala (SADX only)Ram (SA2B only)Raccoon (SA2B only)Unicorn (SA2B only)Dragon (SA2B only)Pheonix (SA2B only)Bat (SA2B only)Sea Monster (SA2B only)Skeleton Dog (SA2B only)Give it the animals of the game it's onMake sure you raise it to be neutralI recommend making a check-list so that you ensure that it works. If you have any difficulties in making a chaos chao, feel free to message me as I have some chaos chao (eight to be exact) so I should be able to help. - Raiwolf
not really the only hack and slash game for the NGC would be Spawn Armegeddon.
