How to Check or Change Your Proton Version in Junk Store
This guide will assume that you have the Junk -Store and Wine Cellar plugins installed via Decky Loader. It also assumes you have some other versions of Proton already installed on your Steam Deck. If you don’t please refer to the following guides on how to install these plugins.
Wine Cellar is what you need in order to use and download different versions of Proton easily. You can have game specific versions of Proton and game settings since Junk-Store creates and installs each game in it’s own prefix.
If you install a game and get a black screen and it closes back to the game page, you most likely need to change your Proton version. We have a lot of luck with GEProton9-7 (we set this as our default for Junk-Store in the developer menu in Steam) and GEProton9-1 when the default doesn’t work. If you get stuck the best place to check for work arounds or Proton versions is ProtonDB.com. Alternatively if it is a game we have tested it will be in our wiki on these pages:
