To be honest.
You might be better off getting some old PC and using it to use emulators on since there is alot worked on. VirtuaNES is in my opinino the best emulator out there for NES. If you havent tried it and have a PC, just give it a try. :-)
But yea, Since Amiga versions of mame may not be kept up to date, then it may be hard to emulate games.
