If you just want mame.. why not try hyperspin?
In hyperspin it's not too difficult to install mame, and it's pretty easy to install a game that uses another systems. Using these means you can install all the zinc, dreamcast, or ps1 games instead of the mame versions that don't quite work yet. Yes you'll have the sony or dreamcast logos reminding you that it's not really the arcade version.. but sometimes the home versions were better (i.e. soul calibur).
