Hello all- I've been looking thru threads but haven't found an answer. I have a N3ds with Retroarch/Libreto nightly build installed that plays a majority of my Neo Geo roms with no problem however several I have don't work. The same rom does work on my pc/emulator, does anyone know or suggest how to tell what rom is compatible? Most recently I tried NeoMr Do, which simply fails. Any help or hints are appreciated, I also see a few errors on the bottom screen when loading roms that do work so it may simply be my bios zip as I tripped through getting this to work to begin with and am novice.. Thanks
