No, don't do anything rash. I need to know a couple things quick. Do you maybe have GameEx installed in two different places? First look here: C:/GameEx Then look here: C:/Program Files/GameEx Also, go to Start/GameEx/Advanced Configuration, go to the last page under Advanced MAME Settings, and check the field that says 'Manually Filter These ROMs' to make sure it's not there. Another thing I want you to try if this doesn't work, under the advanced config again, in advanced MAME settings, add this ROM to the list that says 'do not filter these roms' and update your list once again. Does the game show up? If not, run any MAME game, then go to the start menu again, in the GameEx folder and click on run last game. Does it run the game you just played? We'll try everything!
