@DarkSamus993: Thank you for finding those hex addresses, I was able to change his name back to Sodom on those areas. That was very nice of you on helping me on this, you're the best.
@Psyklax: I also want to thank you for letting me know about bsnes-plus, this could be useful for future SNES projects.
UPDATE: I just discovered that the American & European versions of this game is a lot more censored than I thought, thanks to info from user RealGaea.
On Sodom's stage, his truck has his name on the license plate:
On Guy's stage, the word "KILL YOU" appears on the wall:
On Birdie's stage, there's people peeing in the urinals and when you use a super move, the left stall opens:
So I still need help on this hack, including restore this stuff for the European version as well.
Sorry about this, I did not know that Capcom USA censored a lot more things in the international versions of this port.
