I've been playing around with CPWizard and have had some success with showing what each control is for Mame. I'm now looking at doing the same for some consoles (N64, NES, etc.).
Before I went down the path of trying to manually type in what each button did for each console game, I was wondering if there was some sort of project or file or something that listed what each of the controls were for some of the console games.
I did a search on the forums and in Google but nothing came up, so I figured I'd post and see if anyone else has ever heard of a solution. Apologies if this is a question that comes up all the time.
