Dont know what versions of MAME you used on the PC, but they are Superb..super easy to change the resolution to be exactly like the arcade with Scanlines and all..no borders.
I have seen also the MorphOS version and it is quite good.
As far as 68K Amiga Versions...........I hate the fact that they require Gfx cars to center the screen and to run properly.......it should work fine on a plain A1200 since most old arcade games and NES, SNES, Genesis, have 256 colors or less.
