thanks Robbbert. I knew that mame still used this kind of ini file heirarchy because when I manually changed the name of the ini file to match the source driver name mame then used these settings for all games using its driver. That was why I was ***hoping*** that you could get that functionality back into mameui as it is already there but obviously not working the way it should and (couldn't it just be contained within the MAMEUI code) just make 1 more reason for me to continue using MAMEUI. However I see you point regarding source drivers that are named the same as a game. Are you thinking of taking over mameuifx too! king of the mameui's haha.
