so ive seached the net for the last 5 hours for a complete rom set of mame 0.78 and have found nothing does anyone know of a complete and full set out there?..
also is there a rom compatibility list being made for the current RETRO ARCH build?
you must not have checked the most popular torrent site, which has the set broken into 2 parts. Compatibility for RetroArch should be the same as the corresponding standalone emus.
