Zinc and FB Alpha games are emulated in MAME, so no need to use these emulators or add any games to database?.AAE games are all emulated in MAME, so no need to use this emulator or add games to database?.My understanding is all the 'classic' databases are just taken from MAME set, filtered by manufacturer, so can be disregarded?.Below are some assumptions I have made with regards to the other Arcade Emulators and databases out there, please feel free to comment or correct me on them: I would need to update as each new mame version comes out - hopefully Phulsoff will continue his great work in providing XMLs. Naturally MAME would be the base, and used wherever possible, and I was going to use Phulsoff's unofficial 0.168 database with mahjong and casino removed. To me this is preferable than having them split across seperate wheels for manaufatures and/or systems. I am creating just one arcade wheel on my setup, with as many emulated arcade games as possible on it.
