I have made a few attempts to ensure the mame roms are in the Roms folder under Roms. I modified the mame.cfg to point to the roms folder, not emulator roms. All the Mame files appear, most with a .zip extension on screen. I've tried to play out the mames that have a zip extension and those that appear to import properly ( name is properly showing). Mames with .zip come back with missing files, mostly .bin files, but they are in the zip if I decompress it.

Files that appear right, give me the error below.

I have also put them in the adv mame and mame roms folder with no luck. Mame tries to load, then permission denied, then back to the mame list.

Error says:

Relaunch 2
Sh: 1: /home/pi/pimame/emulators/mame4-all/mame: not found

This is an emulator error versus mame linkage, yet all the mame files per the download package have been placed in the emulators/mame4-all folder

I don't know.
Any advice?
