Hi guys, I have a lot of MAME roms that won't launch with GameEx but do launch with CMD. For example the game 'Viewpoint'; it launches fine with MAME in CMD without command line options. But in GameEx, the game will not launch. If I select the game, the screen goes black for a quick moment and then returns to GameEx. Other MAME roms will launch in GameEx but there are many that won't. I tried it with and without MAME command line options in GameEx. Did not make a difference. All the paths are correct. The same executable and paths are used in CMD. I have attached the GameEx.ini, mame.ini and the GameEx log file in this post. Hope anyone can figure it out? GameEx version: 13.27 MAME version: 0.154 Roms version: 1.53 Thanks, Michel << UPDATE!! >> The rom 'Viewpoint' will launch with GameEx Lite. I haven't tested it, but I pressume the rest of the roms also will launch with GameEx Lite. But with this solution comes a different problem: With GameEx Lite there are no video previews in the games list. Is that a setting in GameEx Lite or in my theme? If I could get the video previews back again, this solution with GameEx Lite version would be fine with me. GameEx.ini log.txt mame.ini
