Thank You. That solved the issue and also pointed me in the right direction on launching it pout if retroarch as well.

Hello. I have vic10 setup and running standalone in MAME 0.253. I can navigate the MAME menu and launch the games no problem. When I try to start from Launchbox it loads the correct machine, but the game won't start, just blank screen. I can then proceed to launch the games from the software list in file manager, but not by selecting the file in file manager. The only thing I can think of is that my "vic10 -cart" parameter is wrong. Many of the files contained in the Zip are .bin not .80 or .e0, but again those same files launch in Mame's standalone menu It also might be worth mentioning that there is no Bios file for this system I was hoping to launch in Retroarch Mame Core, but if I can't launch in MAME then there's another issue to address first. Any help would be appreciated.

Thanks everyone! Two solutions work. 1.) Use the -Rompath parameter and check the two boxes for quotes and extension. 2.) change use -rom1 instead of -cart1 and leave the two boxes unchecked. no idea why my original parameters don’t work in this emulator setup. thanks again, that was driving me crazy.

No luck. I was able to use video to capture the screen that pops up briefly. I'm going to post that and a few images of my setup in case I'm doing something wrong.

Sorry, one other important note. It does launch through Mame 0.253 independently of launch box.

I’m having trouble launching Pegasus as well. It’s working in Mame 0.185 and an old Mess 0.149 setup and figured I’d get everything migrated over to 0.253. I tried turning off parts selection and bios selection and using my prior default command line parameters of pegasus -cart1 and a new parameter of pegasus %romfile% but neither works. I can see some slight difference in the screen that flashes with those two different parameters but I can’t read it. I tried copying the existing 0.185 bios into the 0.253 roms folder as well. Two other software list titles are launching fine in my new 0.253 emulator, atom and astrocde. I'm stumped. Any thoughts? Is there a way to get a log of the failed launch screen that disappears before I can read it? I can just leave it in 0.185 if it comes down to it but that’s admitting defeat.

11.2 That did the trick. Once I changed the priority in LB Settings it worked. Thank you for your help

I’m having this Same exact issue. Prioritize theme Video setting is unchecked and it’s still showing the theme video when a valid snap file is available. Check config file as well and it shows false.
