Recent changes to MAME was the reason they were removed from the list. So yes, they do play pretty good now. Well I don't know the specifics to specs required for those particular games. The specs are listed on NONMAME that are used for the list. I guess the best thing would be to test those games for yourself on your machine and then compare to other users to see what is required. I have no comments on Model3 emulator quite yet as I haven't tried playing anything on it. Hopefully someone will chime in with experience on it. Sorry!
