hmm, yes I'm using GroovyArcade with AdvMenu, the problem is that there is bios roms visible in the list, and games for which I don't have a full romsets (I suppose they're bits and pieces from the romsets I want).
I didn't come around in following Gray Area's advice yes, but will look at the documentation, but while we're on the topic, the only thing resembling filtering is the emulator_roms_filter line, which does not filter anything =7
Anyone with suggestions?
