that’s what I mean though – there is no “roms” folder in the directory with that exe. i’m in “root>home>pi>RetroPie>emulators>mame4all-pi” and the options are folders, obj_mame_rpi, skins, src, .git” in “folders” there is just a txt file, “obj” and “src” have a bunch of sub folders – none called “rom”, “skins” has “source” with nothing in it. I’m not sure where the exe would be looking for the rom files.
