OK so keeping only ROMS checked gives me my filtered list, as does ROMS and Videos. All others that I have zips for (snapshot, flyer, cabinet, marquee, PCB and icon) break when checked then one by one on their own. Am I being a bit dense by keeping these folders zipped? Should I try unzipping them and revising my paths?
Again, cheers for the help and even if I can't suss artwork this is the only ROM manager I have used that works. Nice job!
