Black screen when launching ROM, but works from RetroArch

[budfox78]

I installed LaunchBox 13 on a Windows 11 PC (Hades Canyon NUC, with AMD graphics) yesterday.

For some platforms, like NES, everything works perfectly, but for some others (SNES, Genesis, N64 among those tested), all games launch to a black screen, and never properly start.

I have narrowed this down a bit further:

* When opening the LaunchBox installed RetroArch, and loading the games, everything works fine.

* When launching the games from PowerShell with RetroArch, with the same -f and -L arguments as LaunchBox uses, the issue is reproduced.

* I have also verified that the cores in the shell command exist on the paths provided.

 

Has anyone else come across this issue and managed to fix it?

I realize it's probably a RetroArch issue technically, but a LaunchBox workaround would be greatly appreciated, as it affects any frontend/launcher application trying to leverage RetroArch.
