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 easy to download and manage different versions of Proton — without switching to Desktop Mode.

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 You Use a Different Proton Version?

Use a different Proton version if your game:

  • Shows a black screen, then closes
  • Doesn't launch at all
  • Crashes immediately

To find the best version for your game:
