Hello, Tux, mer-curious. Following the advice of yours, I add some comment at the bottom of the cheat screen which normal player better to know about it.
For the rom part that i patch ($8d5d), is about changing the p2 input to controller 1, that why in practice mode, users can control p2 after choosing character. As i mention previously, if restarting the game or closing the cheat during that short period of time that the control of p2 is changed, it is not restored to normal until closing Raine and reloading the rom.
But now this problem is solved in a new version below. The rom patched part always return to normal as starting (restart) the game or closing the cheat.
Any one interested in my cheat of rbffspec, please update here:
