[Solved]DOS game won't launch via .sh or .conf file in emulation station

Montrovant

Hi!

I've been trying to figure this out my self, but a lot of the information I find seems to be outdated.
I'm running a Pi4 and the official Retropie img.

I have my DOS games located in:
home/pi/pcroms/

In /pi/RetroPie/roms/pc
I have my .sh and .conf files.
I also have +Start DOSBox.sh

Most games run just fine from .sh or .conf but some do not. the example I'll use is Loderunner the Legend Returns.

With this game I get thrown back to emulationstation just after dosbox launch.
If I put the game files for loderunner in /pi/RetroPie/roms/pc, launch dosbox and run the LODERUNN.EXE from within dosbox, it works fine..

These two post are the closest I've come to finding the same problem online:
https://retropie.org.uk/forum/topic/26086/emulationstation-parses-sh-files-into-runcommand-argument-for-lr-dosbox
https://retropie.org.uk/forum/topic/27767/game-won-t-launch-via-sh-file-on-retropie-with-dosbox-emulator

Loderunner.sh:

#!/bin/bash
/opt/retropie/emulators/dosbox/bin/dosbox -c "mount c /home/pi/pcroms/" -c "c:" -c "cd loderunnerLR" -c "LODERUNN.EXE" -c "exit"

Loderunenr.conf:

[autoexec]
MOUNT c /home/pi/pcroms/
C:
CD loderunnerLR
LODERUNN.EXE
EXIT

I have also tried:

Copying the entire dosbox-svn, renaming it loderunner.cfg and appending the [autoexec] part for loderunner.
Moving the gamefiles to /pi/RetroPie/roms/pc and chaning the .sh or .cfg accordingly. It still only works if I launch it from within dosbox.

Any help or direction to other sources is appreciated!
Hopefully It's something obvious I've misunderstood.

@montrovant said in DOS game won't launch via .sh or .conf file in emulation station:

CD loderunnerLR

DOS doesn't support more than 8 characters for folder/filename (not without some LFN add-ons). Shorten the name of the folder and re-try.
Btw, you don't need to create a .sh file if you already have a .conf file, EmulationStation will launch the conf file directly.

That seems to have sorted it! Thank you!

When I stared out I first visited the retropie docs
https://retropie.org.uk/docs/PC/#install-gravis-ultrasound-gus

Which redirected me to this guide from 2015, that suggest using .sh scripts.
Now that everything is working I'll start converting everything over to just using conf-files, and optimizing the games :)
