I have tried everything to get my roms working in the new .8b2. I updated to the newest build and pifba and pisnes are working much better but all of my roms that work 100% in .710 now give me a missing bin error and crash to command line. Is that build of Mame4all using something different than 037b5? I did check all my file names and permissions as well with no change. Thanks for the help
So after updating to .8b3 my issue wasn't solved. I tried several different things with no solution. Finally, just on a hunch I also placed duplicate roms in the emulators/mame4all-pi/roms folder and bingo it worked. I also made sure the permissions were 777. So there must be some break in the shortcut that points to the roms folder when running.
