Unable to start DOSBOX, getting error with Runcommand and/or permissions

lordcrammy

I have RetroPie working on an RPI3 right now. I've got all of the emulators working fine, with exception of DOSBOX.

I've installed it, updated it, re-installed it, and no matter what I try, when i open the MS-DOS section of the emulator list, then choose "+Start DOSBOX" it just goes to a black screen and puts 2 lines up on before going back to Retropie.

The lines read:
sh: 1: /opt/retropie/supplementary: Permission denied
sh: 2: /runcommand/runcommand.sh: not found

Does anyone know how to fix this?

Use markdown to format your posts - see http://commonmark.org/help/ - and put large logs on a pastebin type site like http://paste.ubuntu.com/ http://pastebin.com/ or similar.

You should wrap the XML in a code block otherwise information is not displayed correctly.

You can mark this SOLVED! I remembered I was following another site's suggestion on creating ".SH" files to automatically launch games in DOSBox without having to manually type the commands. Along the way, I had modified the es_systems.cfg file to give it an entry so it would show as an emulator because it wasn't coming up after installing DOSBox.

It turns out, there's more than one es_systems.cfg file. The one I posted above was in the ETC path. I found another one under /opt/retropie/configs/all/emulationstation/

When I opened it up, I guess I had somehow split the line:

    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ pc %ROM%</command>

into this:

<command>/opt/retropie/supplementary/
runcommand/runcommand.sh 0 _SYS_ pc %ROM%
</command>

Once I backspaced each separation so it was on one line, it worked! Well, the "+Start DOSBox" entry works, but the ".SH" scripts I made do not launch the games properly, so that will be my next mission. Thanks for your help BuZz.
