if i select "game with no device set" under device droplist
i lost like 100games, example 19xx by capcom go hidden.
tried utilities from category but dont work, maybe because i have wronged catver.ini?
i want hide MC PROGRAMMER and VGM PLAYER because aren't real games, i can't play with this "device rom", so to answer about your question, i want hide only this undesired "devices", and yes if 19xx.zip or other real games have devices included, i want them on list of course .
hope i have explained what is the problem ^^
