Well, most good amiga arcade conversions are great in mame..
Some that just didn't translate well but are classics
After burner II
Blood bros (should have been perfect for amiga)
Dodonpatchi (pixel perfection)
Galaxy Force II
In the hunt (Cave or IREM, always good shooters)
Rainbow islands, the way it should be played
Street fighter Alpha III (just perfect)
Strider (eat that megadrive!)
Somethin fun for amiga fans
Lemmings, a prototype arcade never released.
