Cannot launch MAME roms from Launchbox

Hi all, I am having trouble launching any MAME 2.70 roms from a new Launchbox install on my desktop system.

I am not a brand new user, I have a second arcade box that works fine, and I just redid my MAME set to 2.70 using the Full Set Importer successfully on that system. But when I tried the same procedure on my desktop, it installs MAME but will not launch any roms. The ROMS try to launch, the screen blinks and it fails.  

If I launch directly MAME 2.70 and add the rom path inside the MAME that got auto-installed, I can play games from MAME's own picker. The issue is with Launchbox invoking the emulator. The options are exactly as the auto-install set them. I tried removing almost every option and no luck. The logs complain about an image file being in use but I do not know if that is the issue.

Adding a debug log of my trying to open 1943u.

Thanks for any advice.

I know you said you're not new and you've probably tried/did these rudimentary things, but based on what you shared, this is all I can think of.  Also, the "cannot access the file [image_file]" exception occurs after starting the LaunchBox shutdown process (i.e. click the X to close LaunchBox).  So is not related.

 

When (in standalone MAME) you went to General Settings < Configure Folders, and set the ROMs folder, did you click Save Settings?  aka, Saved to the rompath in mame.ini.

If so, try removing -rompath %romlocation% from the Default Command-Line Parameters.

If not, leave that in and double-check 1943u's Application Path.  (D:\LaunchBox\Games\MAME 2.70 (Merged)\1943u.zip)

And just in case, check in the Emulator section that it's pointing to MAME 0.270.

Lastly, though I don't think it should affect things, try un-checking Attempt to hide console window....

Thanks JoeViking245, I just figured out what was happening.. basically me being an idiot. I somehow had copied only a subset of roms I thought I had. Nothing to see here... 🙄

Thank you for helping!
