Ok I've been searching the internet for a way to combine or start learning how to edit games, arcade games. Now the roms I want to "combine" are Saturday Night Slam Masters by Capcom, and Muscle Bomber Duo, it's clone. Why I want to combine them? Simple, both games have good and bad things, and I want to combine the good things into one single game and make it playable on M.A.M.E. Now if someone here can help me by telling me where to find programs that can help me in that would be great, I have the rom for M.A.M.E. and what I want to do is basicly to add moves that already exist from both games and make a new one, but I've been told that I would have to do a lot of coding... Now please help me find some programs that I can use to edit those games and combine them...

Whoever told you that it'll require lots of coding was right. But there's more:

1. You need to "disassemble" the game code to get some kind of Assembler source code. Use a disassembler for that, but you need one for this specific CPU.

2. Figure out the purpose of the code sections. Ideally you should have some years of programming experience for that, and be able to read Assembler code fluidly.

3. Write new routines that do the job of the old ones + your new moves. Insert these (and the new data that you might require). Note that you might have only a limited amount of ROM space for that, and that the original programmers might already used almost everything of it.

But the moves I want to add already exist and are used within the two games but the clone game uses the original's engine and some of it's moves including some new ones, but it doesn't include the moves i want in the combined game.... Are the two links below your reply programs that I can use, because I think they are for snes (duh).... But I was thinking can I add the moves I want from the original to the clone and thus combining them in the clone version?

Yes the links are for the SNES. I don't know much about arcade systems, but the same principles should apply.

It's probably not likely that moves are saved as data that can be copied from one game to the other. They're probably hard-coded into each game.

So can you help me where to find the disassembler for that specific CPU?Huh And a question: Are the Capcom Play System 1, and CPS 2 CPU-S or what because I seen that the arcade system for Saturday night Slam Masters is CPS-1 and Qsound whatdoes that meen???

EDIT:

I found out something about CPS-1 it uses a motorola 68000 at 10MHz as a main CPU, hope that helps, but the roms for mame are packed in zip files, and in those u have rom files and bin files, now what does that mean please explain those things a bit more or find somebody who can help me pls...

Romhacking.net doesn't have 68k disassemblers in the utilities section, but Google does: link. That's all I can help you with, as I don't know much about that CPU and even less about arcade systems.

Maybe someone else?
