Couldn’t find an answer.

Is there a way to make emulators added as non-Steam games talk to the games, in Game Mode? I’m not using RetroArch for reasons.

So e.g. I installed SNES9x as a non-Steam game (rather than RetroArch) but it can’t talk to the SNES games I installed via EmuDeck. I had to make desktop folders for those .isos, and point the emulator to them. It’s not a big deal, but:-

There must be a command you can enter into the games’ profiles which I think looks something like %COMMAND% but I have no idea what it is, that would hook up the emulator and the game, in Game Mode.

Does anyone know? Thank you in advance.
