Very busy these days so I haven't had time to fire up the HTPC with work, school and now moving. Now, I have installed the codecs and that got some systems working - for whatever reason my Game Boy and Game Boy Color snaps needed them to work. I have not tried renaming my files within my archives (.zip, 7z etc) yet however I don't get how mame works when they have files within a archive. I wish the snap best match, well was tied to archive name but hmm maybe I need to try a database as I don't use any.
