@LeatherWing said in Pi 5 Dosbox failes to launch. Bookworm 64bit lite:

Assuming I'll need to figure out how to force a rezolution on dosbox-staging and cross my fingers.
If you have any suggestions for the format, I'm happy to hear 'em.

Use the runcommand launch menu and choose a resolution from there. The error looks like it's coming from the TV, indeed. You can take a look at the log file (/dev/shm/runcommand.log) and see which resolution dobox-staging tries to use.

@winterelf That's not how it works. The lines you have produce F9 and LCTRL inside the emulated DOS system, they're not remapping the host system's keyboard.
In order to exit Dosbox, you'll need to have the hand_shutdown mapped to the combo you want, which is what's missing from your mapper file.

@mitu Thank you so much! Indeed, it was precisely in the full path to the CDROM folder.

As a result, the command looks like this:

[autoexec] MOUNT c /home/pi/RetroPie/roms/pc-games c: cd Rayman MOUNT d /home/pi/RetroPie/roms/pc-games/Rayman/cdrom -t cdrom RAYMAN.EXE EXIT
