ScummVM only launches from Emulator and not Emulationstation list

HappySpaceInvdr

ScummVM games will not launch from Emulation Station - they crash out with this error in the runcommand log:

pi@retropie:~/RetroPie-Setup $ cat /dev/shm/runcommand.log
Parameters:
Executing: bash /home/pi/RetroPie/roms/scummvm/+Start\ ScummVM.sh "Full Throttle"
scummvm: Unrecognized game 'Full Throttle'. Use the --list-targets and --list-games commands for a list of accepted values.
Usage: scummvm [OPTIONS]... [GAME]

Try 'scummvm --help' for more options.

But if I launch ScummVM I can run the same games no problem.

Here's what I'm running (I just built my Retropie yesterday, so it's all latest versions):

RetroPie 4.8.8 (03b7224)
ScummVM 2.8.1 (Jul 3 2024 22:49:25)

I found an old post from 2016 with the same title, but the solution was to update ScummVM... this unfortunately isn't an option for me as I'm already on the latest.

I have my files set up exactly as described in the ScummVM docs on this site.

e.g.

pi@retropie:~ $ ls -l /home/pi/RetroPie/roms/scummvm/Full\ Throttle/

If you have created .svm files for the games, then they will not work with the standalone ScummVM but only with lr-scummvm.
Open the GUI and add the games from there. After that, restart EmulationStation, and the shortcuts for the games will be visible.

Thanks for the explanation - what are the pros/cons of standalone ScummVM versus lr-scummvm?

Pross
With the standalone version, you don't have to create the .svm files. Also, it has way better performance than lr-scummvm.

Cons:
In the EmulationStation menu, you will see the short name of the game. You have to edit the metadata or use a scraper if you want the full name.

You may also try the scriptmodules I put together a while ago, but do still work fine. These make ScummVM game setup and switching between ScummVM and the lr-scummvm a breeze.

With that branch you just have to have a file structure like this in the ~/RetroPie/roms/scummvm/ folder:

...
├── Monkey-Island-1 The-Secret-of-Monkey-Island/
├── Monkey-Island-1 The-Secret-of-Monkey-Island.svm
├── Monkey-Island-2 LeChucks-Revenge/
├── Monkey-Island-2 LeChucks-Revenge.svm
...

The actual folder name and .svm filename do not matter per game, they just need to be matching per game like above. The *.svm can also be empty initially, the game id will be filled in by my scripts. Just put the required game files into the respective game folder as per ScummVM wiki.

Start a game with the native ScummVM once, then you may switch at the second launch to the libretro ScummVM in the runcommand menu. And switch back and forth. That's it, that's all. :)
