This FAQ addresses common questions about using GOG titles with Junk Store on the Steam Deck.

Installing the GOG Extension

The GOG extension is available as a supporter benefit. You can purchase it via Ko-fi or Patreon using the button below. Once completed, you’ll receive download access and emailed instructions on how to install it and link it to your Junk Store plugin.

Note: The GOG extension is currently in maintenance-only mode. This means we’ll continue fixing bugs and ensuring compatibility, but we’re not actively adding new features. Continued support depends on user interest and purchases.

Ko-fi Patreon
Where can I find the GOG extension?

It is only available to our Ko-fi & Patreon supporters. You can either subscribe as a monthly supporter, or you can purchase it as a one off through Ko-fi or Patreon. Once you have it, you have it. We can't take away Gog functionality/integration with the Junk Store plugin. All funds go back into the enhancement and development of Junk Store.
Why isn't GOG free to use?

GOG support is available to paid supporters, and while we'd love to offer it for free, there's a lot of behind-the-scenes work and resources involved in creating and maintaining Junk Store. We appreciate your understanding and support as we continue to improve and expand Junk Store. All funds go back into the enhancement and development of Junk Store.
Does Junk Store automatically install DLC content too?

Yes, at the moment it will automatically install DLC content by default.
Does Junk Store support GOG cloud saves?

This has not yet been looked at for implementation at this stage as it isn't a trivial problem to solve. It will require more resources and time than we currently have available.
How do I uninstall and clear game data?

In Junk Store:
  • Open the sliders ☰ menu for the game
  • Choose 'Uninstall'
  • Then delete leftover files in either
    • ~/Games/gog
    • Or your microSD under /Games/gog
Once you have located the games folder you can delete any remaining games files/data.
Where can I locate saved data for my GOG games?

First, you need to get the Steam ID for the game from the Junk Store game page. It will be at the bottom of the game info.

You will then need to navigate to the save files in your compatdata folder. This is an example of the path for saved games in GOG:

.local/share/Steam/steamapps/compatdata/2237305483/pfx/drive_c/users/steamuser/AppData/Roaming/Lonely Troops/Hero of the Kingdom II
How do I find save data for my games?

  1. Find the game's Steam ID at the bottom of its page in Junk Store.
  2. Navigate to the following path on your Steam Deck:
    ~/.local/share/Steam/steamapps/compatdata/<SteamID>/pfx/drive_c/users/steamuser/
  3. From there, follow the path used by your game - for example:
    • /AppData/Roaming/Lonely Troops/Hero of the Kingdom II
Each game may store saves in slightly different locations depending on how it was packaged or ported. Look under AppData, Local Settings, or Documents within the Steam compatibility prefix.
Does the extension support DOS and ScummVM games?

DOS games and some ScummVM games are not supported via the GOG extension.
Does the GOG extension support native Linux games?

No — the GOG extension is designed for Windows games running through Proton. Native Linux games from GOG are not currently supported, as Junk Store relies on Proton’s compatibility layer for game execution and integration.
