Need advanced compatibility tools for challenging games in Junk Store? Wine Cellar gives you access to GE-Proton, Wine-GE, and other compatibility tools beyond Steam’s default Proton versions. Perfect for games that need special Windows component configurations.

Intro

This guide assumes you’ve already installed Junk Store via Decky Loader.

If you’re not sure how to change the Proton version used for a game, refer to:

What is Wine Cellar?

Wine Cellar is a Decky plugin that makes it super easy to download and manage different versions of Proton—without switching to desktop mode.

Yes, there are other tools like ProtonUp-Qt, but Wine Cellar is the most Deck-friendly option. We recommend it because it’s simple, clean, and works right inside Game Mode.

When Should I Use a Different Proton Version?

If you launch a game and it:

  • Shows a black screen, then closes back to the game page
  • Doesn’t start at all

Then you probably need to switch your Proton version.

To find the best version for your game:
