@hooperre Is the command output depending on the starting folder ? I.e. you're in the /.alttp_msu folder when running that command ?

hooperre

@mitu I had the folder name mixed up and it has been updated in my original post.

The command is being launched from the ./RetroPie/roms/snes folder. The actual alttp_msu.sfc and all the .pcm files are located within the ./RetroPie/roms/snes/.Legend of Zelda, The - A Link to the Past (USA)[MSU-1]folder.

I don't think it depends on the starting folder. If I just (from the command line) ran the .sh file containing either one of the blocks of code written above:
sudo bash home/pi/RetroPie/roms/snes/alttp_msu.sh
the file runs correctly, and with all the correct RetroArch configs, but this doesn't happen when launching from EmulationStation. I'm not sure if launching it from ES changes the way that RetroArch handles it somehow or something.

@hooperre You can see the launch command used by Emulationstation by looking at the /dev/shm/runcommand.log - it should be the first line. That being said, the command you posted (using runcommand) seems like something similar to what Emulationstation would launch.
If the launching commands prove to be the same, try running with verbose logging when you launch from Emulationsation (by using the runcommand launch menu) and maybe there's some clue in the detailed log about what's missing.

Ah. It's calling for the actual .sh file itself when I use the runcommandas opposed to the .sfc. Dump:

Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-snes9x/snes9x_libretro.so --config /opt/retropie/configs/snes/retroarch.cfg "/home/pi/RetroPie/roms/snes/alttp_msu.sh" --appendconfig /dev/shm/retroarch.cfg

Not sure how to get around that. I'll try the other one again.

The other script with verbose logging: https://pastebin.com/BuUJbxN9

Appears to be calling for the .sh file as well. That one makes less sense to me.

That's not correct. Did you customize the EmulationStation system config file (es_systems.cfg) and added the .sh extension as a valid ROM ? By default, .sfc is one of the included extensions, so if you have the .sfc ROM file in the folder, runcommand should invoke the correct emulator.

hooperre

I did not add .sh .SH to the es_systems.cfg.

The script works well in the ports folder/menu in emulationstation and will launch the MSU-1 version of the game. It appears that runcommand is ignoring the text within the file and just launching the .sh file as an accepted rom. I can't figure out a way around this and suppose I'll just have to create an extremely messy MSU-1 folder.

@hooperre Can you post the es_systems.cfg on pastebin.com to take a look ? Is your .sfc file addd in the snes folder ?

hooperre

@mitu

es_systems.cfg: https://pastebin.com/3V4uAygY

alttp_msu.sh is located in //home/pi/RetroPie/roms/snes containing:

/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-snes9x/snes9x_libretro.so --config /opt/retropie/configs/snes/retroarch.cfg "/home/pi/RetroPie/roms/snes/.Legend of Zelda, The - A Link to the Past (USA)[MSU-1]/alttp_msu.sfc" --appendconfig /opt/retropie/configs/all/retroarch.cfg

And alttp_msu.sfc is located in //home/pi/RetroPie/roms/snes/.Legend of Zelda, The - A Link to the Past (USA)[MSU-1].

According to your config file, the snes system doesn't launch .sh files

 
  <system>
    <name>snes</name>
    <fullname>Super Nintendo</fullname>
    <path>/home/pi/RetroPie/roms/snes</path>
    <extension>.bin .smc .sfc .fig .swc .mgd .zip .7z .BIN .SMC .SFC .FIG .SWC .MGD .ZIP .7Z</extension>
    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ snes %ROM%</command>
    <platform>snes</platform>
    <theme>snes</theme>
  </system>

but it should be able to launch .sfc files. I don't understand how it launched runcommand with a .sh file.

@hooperre I was trying to do the same thing and I recently got it all sorted out. I described what I did to get it all working nice and clean in another thread.

Check it out here: Load NON-PC rom with a script?

@joelkolb Nice! They've been in my ports folder! Thanks!
