Trying to play some imported ROMs. Launchbox and RetroArch imported them just fine.
When I double-click or click play, I get the cursor spin and then nothing. If I right click on the game, open retroarch and manually select the core (which is configured correctly in Launchbox) and select the content, it works fine.
LaunchBox v13.24
RetroArch v1.22.2 / Core Mupen64Plus-Next (2.8-Vulkan 680e033)
Windows 11 Professional 25H2 Build 26200.7462
Suggestions?
Other platforms work ok on newly imported ROMs.
