I came from the olden days of "Mame32" on Win95/98 and QMC2 just seemed like the last good Linux frontend that followed that type of look/feel and windowed style desktop program with all the info and extras just a few clicks away. For awhile there was a frontend called MAME+GUI or MAMEPGUI that worked well in Linux and also had the Mame32 look and feel. It stopped being maintained about 8-9 years ago. What are the other Linux users out there using nowadays?
