I am running the latest version of Retropie with Libretro MAME 2003. It’s my understanding that this version uses 0.78 roms. I have a set, but when I attempt to play games on the Pi, only some of them will run. Others will go to a black screen as though the game is loading, but then will return to the game list.
I’ve googled quite a bit but can’t figure out what’s going wrong here. Has anyone else encountered this? Can you help?
