Scummvm enhacements about gamehub HOT 10 CLOSED

I recently revisited this issue. I tried to use some SCUMMVM games with the custom emulator feature. It's promising, but it won't work as expected with SCUMMVM since it requires to change the directory to the game directory, for every game. The custom emulator feature does not allow that (or at least, I don't know how to do it without creating a custom script).

Moreover, maybe could be a good idea to remove the Dosbox/Wine/Proton code and re-add them as custom emulators.

Yes, it currently uses install_dir of Emulator as a working directory.

Possible solutions:

• Use install_dir of Game
• Provide option to choose which directory to use (game or emu)

First solution can possibly break emulators if they require to be launched from their directory.
Second solution may be a bit harder (or may not). What should be default for that option if second will be implemented?

No. CompatTools and Emulators are different things and work differently.
Also Emulators can depend on CompatTools itself.

Provide option to choose which directory to use (game or emu)

I think that's the best option. The default could be the install_dir of Emulator. I believe this is the most common configuration for Emulators.

Fair enough. So, do you think that SCUMMVM should be a CompatTool or an Emulator?

I don't know. ScummVM uses *.ini for configs, it's a bit harder to detect than dosbox_*.conf for DOSBox. Also I don't think that ScummVM is as popular as DOSBox.
User can add it as a custom emulator if needed.

Added as a compat option for CustomEmulator tool

Options list now shows translatable option description for options instead of name (name is shown in tooltip instead). I don't know if it's better than it was before.

Using scummvm --auto-detect in the game directory works 99% of the time. Time to test it!

Works great!. My last suggestion is to include the scummvm custom emulator if GameHub detects scummvm in the PATH. If you don't want to implement this feature, just close this issue.

How does scummvm --auto-detect work? Does it just launch game if detected? Is there a way to use that autodetection but without launching game?

Yes.

Use --detect to show games in the current directory. Some examples:

$ scummvm --detect

It works great! I will test with a few games and close this issue.
