Been searching around *some* for this via google, but it's a tough one to come up with useful limiting keywords, so I figured I'd give it a shot here...
Does there exist an easily machine-parsed file listing the controls for each game in popular emulators? I.E. One saying something along the lines of Emu xxx Game xxx P1B1 Fire P1B2 Special P1B3 Dance. If so, where can I find it? If not, is there any interest in one existing, at least for MAME? My wife would kill me if I took the time to do all of them, but I would be happy to set up the file format and split the labor with 2-3 other people.
On a related note, what's the fastest way to generate a parent-only list of games supported by MAME, or is the fastest route for me to just toss together a quick little app to get that from the -listinfo output? Also, are there any examples someone knows of where the controls are different between parent and clone?
