To hack Sonic Adventure 2 Battle, you need to buy Action Replay. Hook up action replay to your gamecube and put in ar codes. Codes are found on the internet.
Hacking Sonic Adventure DX is a different story. First buy the PC game or download the demo found online(I bought mine). Then you download the mods found online and then copy and replace them into the system folder found near the "sonic.exe".
I do not mean to be lazy, but tutorials found on hacking sadx and sa2b are easily found on YouTube!
The only way you can get a Tails Chao and an Amy Chao in SA2B without Action Replay is by via hacking.
