My filter above includes eg 842way.tag if that file is present. I can see the advantages of the way it works, eg my filter would also select '8way_fighters' and 8way_shmups' if I had those tag files.
I would prefer a rule that picks only '8way' and '2way' and not other matching filenames. It's not that important, now that I know what's going on. It seems like equals instead of contains should give me what I want, but I can't find a syntax that works. eg Tags equals 8way doesn't select any roms.
