I spent a good part of today installing Retro Pie. Apart from a few performance issues with some emulators (maybe because also running Apache and MySQL) I have been able to get several of the emulators up and running. I am however having trouble with the MAME emulator.
All the ROMs in the .../mame/roms folder appear in the menu in emulationstation and I am able to select a ROM and launch the emulator. What happens then is that the emulator prints out that is loading each of the files in the ZIP file and then immediately after that prints out an error for each file that it cannot be found. Is this a configuration or permissions thing or something else? I have the same problem no matter which ROM zip file I select.
Any advice to fix the problem would be greatly appreciated.
