So EmulationStation runs Runcommand.sh internally? It doesn't have to be called by an sh file? What about just dosbox? I have no problems executing the sh files with that in emulationstation or cli. Only reason I use lr-dosbox is because I can't seem to control the volume of my monitor's speakers directly.

I made an ARM64 build of dosbox-core:

https://github.com/realnc/dosbox-core/releases/tag/latest_build_linux_arm

I don't actually know if it runs, since I don't have an ARM machine. In theory, it should run fine on RPi 4 since it's built on arm64v8 Ubuntu 16.04.

@dudleydes said in lr-dosbox, how use a general config in orde to speed up execution:

What do you mean by

can't be shutdown (even remotely)

The whole system (the normal Dosbox package that is) freezes when trying to open the key mapper. Hence a remote shutdown isn't possible. Somewhere I read that this is a known bug.

@dudleydes said in lr-dosbox, how use a general config in orde to speed up execution:

To exit DOSBox automatically after quitting a game, you can add the command exit as the last command in the [autoexec] section of your conf file.

Yes, totally forgot! Thx!

@race Navigate to /opt/retropie/libretrocores, create a new folder named lr-dosbox, put the dosbox-libretro.so file into it, then add this line to /opt/retropie/configs/pc/emulators.cfg:

lr-dosbox = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-dosbox/dosbox_libretro.so --config /opt/retropie/configs/pc/retroarch.cfg %ROM%"

[Assuming you've already installed regular DOSbox here.]

Update: I found the culprit! Turns out that the file libretro.h had this struct definition twice:

struct retro_midi_interface { retro_midi_input_enabled_t input_enabled; retro_midi_output_enabled_t output_enabled; retro_midi_read_t read; retro_midi_write_t write; retro_midi_flush_t flush; };

This confused make since you can't redefine a struct once you declare it, causing errors and an eventual crash. Removing one of the struct definitions appears to have fixed this issue.

I uninstalled and reinstalled DOSBox with the dispmanx SDL1 backend and it corrected my issue with screen tearing.
