[Hacc]

One of my favorite games to hack. It's a pain in the ass, too.

Feel free to improve this code, or create a better version. You'll be invulnerable to damage, won't be able to counter any attack (Paul's Back+LP+LK/RP+RK counter, for example), some moves are missing (you won't be able to do the double-fist smash after Jack-2's LP+LK grab), and auto combos won't be available in Practice mode.

Someone asked me how I hacked the "Select Same Character" codes. I initially found it, by debugging (set a breakpoint write on the address, pick a character, and kill the sw v0 with a nop) the characters unlocked value (000C02FE for the default character list), for each player (801BDF50 - P1; 801BDFF8 - P2) in Team Battle Mode. I just applied that process to the other modes (search for the current unlock value and debug). It can also be achieved, by keeping the character total value the same (30h). These were my notes for that method:

P1 Character Table (Team Battle Mode; default is 30h)
301BDF64 00??
301BDF68 00??
301BDF6C 00??
301BDF70 00??
301BDF74 00??
301BDF78 00??
301BDF7C 00??
301BDF80 00??
301BDF90 00?? (not sure what this is for)

P2 Character Table (Team Battle Mode; default is 30h)
301BE00C 00??
301BE010 00??
301BE014 00??
301BE018 00??
301BEE1C 00??
301BEE20 00??
301BEE24 00??
301BEE28 00??
301BE038 00?? (keep as 30h to select the same character. Changes to 26h, when a character is selected)
