I’ve done tons and tons of testing of MAME. by far the best one to use is lr-mame2003 with mame version .106 roms. You’ll get the largest number of roms to work that way.

don’t you mean mame version .78 roms? that’s the romset that lr-mame2003 needs. i agree with you it’s the best mame emulator.

@electronictofu
if you’re using mame set 0.375b5, you need to use lr-imame4all or mame4all-pi – these 2 systems work with that romset. mame2003 needs a later one so you’ll have to rebuild the set, or (better) get a new 0.78 set.
