I can’t seem to run any ROMs with lr-mame2003. Not a single ROM. I have used “mame2003-lr-no-clones-no-neogeo.xml” to rebuild and followed the instructions provided up higher on the page. I am rebuilding from a full 0.162 set. I am new to this, but I have also successfully rebuilt ROMs for lr-fba-next and lr-imame4all without any problems.
List of some ROMs I have tried (including many more)…
1941: Counter Attack
Alien vs Predator
Super Street Fighter II
TMNT 1 & 2
