There's a program called WinHex. You can use it to mode anything with a Hex code as long as you know what line of code affects what in the game.
Mike have you figured out what line of code does what or are you just playing around with different hex values till you get something?
The latter. I can't find a program anywhere or any type of reference as to what the lines of code control. I know what lines control CERTAIN features, but that's about it.
Actually all you have to do is rezip it and run it in mame. I messed with a few Street Fighter roms, but ended up with nothing. There is like 18 columns and over 720 lines of code.
Doing that wouldn't be of much use, you'd need to disassemble both roms so you can understand what the changes were actually doing.One starting point though could be to take an eprom compare tool and look at the differences between say turbo 3.1 and rev. 3.0 and that would show you what was done to make turbo 3.1. Just a thought.
