mame2003 is a complete joke, I started to filter my game list and noticed that over 100 broken games, but those same games do work on mame2010
Michael Jackson moon Walker --> parent does not work, but the clone game works?



?
the majority of Capcom games don't work,
I set mame2010 as my default emulator *you will need to rebuild your roms to MAME 0.139
games that don't work on MAME are run on the Lr-Fbalpha core
NegoGeo MVS runs on FBA
Most of the Capcom games --> FBA
Cave --> FBA
Poly Master Games --> FBA
I only have the Williams games running on MAME2003, as you know Williams game need to generate a cfg file (when you first load a game).
they don't do that when you run them on MAME2010
