While I know GoG isnt officially supporting the Steam Deck (Yet, comon Gog! Dont sit on that gold mine of potential!)
Was wondering if anyone managed to get Epic Pinball working? Through basic heroic launcher, doesnt seem to do the trick, but saw some others managed to get the gog galaxy installer working and maybe that did the trick?

Anyone have some insight? Thanks. :)

Epic Pinball is a MS-DOS game running on the Windows version of DOSBox, so I think the most foolproof way to get it to work on Steam Deck (which is running Linux) is to:

1. Install the Linux version of DOSBox on Steam Deck.

2. Copy the game files from your installed Epic Pinball to Steam Deck. (I don't think you need to copy the files under subdirectory "DOSBOX", only the files from the main Epic Pinball installation directory.

3. Check the files 'dosbox_epin.conf' and 'dosbox_epin_single.conf' whether you want to migrate them to Steam Deck, but the game probably runs fine even without them. I think you set up the sound card options with SETUP.EXE and run the game with PINBALL.EXE (from within DOSBox), even without needing those config files.

The same applies to all GOG games running on DOSBox. I just makes more sense to run such games on the Linux version of DOSBox, rather than trying to run the Windows version of DOSBox (that comes with the GOG version) in Linux, by using e.g. WINE.

Alternate Step 1: Use Dosbox Staging. It's better, ahead of most variants in the pipeline, and is technologically more sane.
