i got the games to work in mame and in gameex now. it was the version neo-geo bios i was using. the next problem is when in game ex looking at the list of games i have in mame. they arent game titles but the name of the files. for example, instead of metal slug 3 its showing me mslug3. the name of the zip file minus the extension. when i go into game ex to update my game listinfo.dat it freezes or gets stuck at 25%.
