I used the full set installer feature and imported my full set of arcade rooms. Everything is great so far. BUT, now when I import another system like Atari 5200, it sets it up like I did for the arcade roms and not like the good ol way of doing it. When I associate a platform with MAME, it goes through the arcade setup, not the way I did it before. It seemed to start doing it right after I utilized the full romset importer feature. Is this normal?
