You have been a great help tonight. Thank you so much. I appreciate you taking the time out of your night to help.

Just finished some Dig Dug and Star Castle That would be the MAME 2016 core right? Do you happen to know which version of MAME that core is built off of so I can target the appropriate ROM set? Thanks again. Just had some fun playing those games.

BOOM! You got it! Thank you for catching that. Sorry for my lameness. I know that I need to update my ROMS as well as probably running the mame.exe (instead of the RetroArch library) and I hope to move to that soon. Thanks again for the quick replies. I do appreciate it. I love the app and look forward to getting even more EMU's up and running. Thanks so much for the help.

You are awesome on the replies. Thank you. If the core wasn't there, wouldn't RetroArch subsequently not work? I know they are present because when I load the core manually (via RetroArch GUI) and then I load the ROM, it works. And yes, these are old ROMS. I haven't ran a checker on them yet but I do know that they are at least 10 years old. Thanks again.

Thank you for the prompt reply. I do not have any of the middle section checkboxes checked

I am having the exact same issue. Roms launch fine through Retroarch itself but do not launch via LaunchBox. Same Mame core and I have verified the Platforms configuration several times. Any help would be appreciated. Thank you!
