Where are you roms located ? Is it in the LaunchBox “games” folder or inside the “roms” folder of your mame emulator?

I’m having the same issue. I did notice if you right click the game in LaunchBox ( not big box) there maybe more than one version and it might be trying to load the bad one over the good. I noticed this with 1942. The first would look like it’s gonna load then back out to LaunchBox but the second would open like it’s supposed to. Wish I knew why it choose the bad over the good. Ended up wiping it all out and starting over again for the 10th time. I use attractmode for pc also and I never get this issue with the front end and the rom itself and I wanna use LaunchBox so badly but I only care about mame not the others. Works great for consoles though.
