Mame 2003-plus Reference: Full Non-merged Romsets !!link!!

: Ensure your ROMs match the MAME 2003-Plus core version; using standard MAME 0.78 sets will work for ~95% of games, but you'll miss out on the "Plus" additions and bugfixes.

Note: While MAME 2003-Plus is based on MAME 0.78, it is a unique fork. Ensure you look specifically for "MAME 2003-Plus" or "MAME 2003+" Dat files to ensure the best compatibility, as it includes backported games that did not exist in the original 0.78 build. mame 2003-plus reference: full non-merged romsets
