I am currently setting up a cabinet, and am using Game Ex for the front end. I am running MAMEui 64 and have 50 roms installed so far. All 50 roms work great in MAMEui 64, as well as a couple of other front ends I sampled. However, in game ex, there are 4 roms that won't show up- burger time, missile command, Donkey Kong Jr. and Galaga 3. Here's what I've tried so far: set verify roms to false, removed/ disabled all filters, set allow imperfect games to true, and set only working games to false. I went into Game Ex and updated the list several times, but those 4 roms still won't show.
Thanks in advance for any suggestions!
