Good to know, this was a pre-built/pre-configured drive so using RetroArch is based on the drive author's recommendation. I don't know why he chose RetroArch instead of Mame, but the setting of 0 doesn't seem to be a valid setting (at lesat every reference I read has a value of 2 or 3). Thanks for the help, I'll ask the creator of the drive if he has a reason to not be on MAME but just glad it is working!

It is, being a noob I wasn't sure which (retroarch or mame.exe) was running the games but it was - in fact - retroarch. I was able to track down the offending line which was : video_max_swapchain_images = "0" I basically did a binary search on the config file until I found the line that stopped the load. No idea WHY that was causing it but commenting it out fixed the issue.

I think I'm on to something ... So one thing I noticed was that when I ran from the command line , it DID run, but I didn't notice it wasn't picking up the config file. That led me down a path to see if that was a factor. If I run WITHOUT the config file, games launch. If I run WITH the config file, they fail without so much as a peep even in verbose mode. Config file attached. ADCRetro_MAME.cfg

Thanks Retro, I see a platform named "MAME" that is associated with this emulator. Also tried the path suggestion.

Games work ok at the command line, but when using the LB or BB UI the game will start loading and then return to the menu. I'm attaching a LaunchBox log file that shows attempts to launch several games, and the config screens asked for in the pinned thread. Debug 2024-01-18 03-08-51 PM.log Debug 2024-01-18 03-18-58 PM.log
