As Roman comments, your best bet is Logiqx's MAMEDiff. To use it you need to have clear what the emu can do (loading by crc and such) and how you want to have your sets, because there are many combinations and not all would work with all emulators. Logiqx already has many supplements created for major emulators against MAME.
