Hi! I installed Batocera on an old Dell Optiplex 760 and I have been having some trouble with it lately. Some systems I wanted to play using batocera include MAME, Atari 2600 NES, SNES, N64, PS1 and GameCube. I have no problems when playing NES, SNES, or Atari 2600, however, when I try to play MAME or Gamecube it keeps returning me to the home screen and with the gamecube an error message pops up, and none of the PS1 games appear in the games list except for GTA2 even tough they appeared in the files. Something similar to the GC and MAME situation happened for the N64, but that problem was solved when I changed the emulator used so I believe that these problems can be fixed if I do the same with the other systems or find different roms in the PS1 case, but when I tried to do it I realized that there was only one emulator option. I don´t remember when or where I heard that I could add emulators so correct me if I´m wrong, but I can´t find any folder or something that hints towards emulators. Please help. By the way, I appreciate a lot the effort that the contributors have put into batocera and I hope one day I can contribute too.
