How to Download and Install the Dolphin Emulator?

Before you can begin to play GameCube games on your Steam Deck you will need to download the emulator onto it. You can do this by first switching your Steam Deck from Game Mode to Desktop Mode, as you will then have access to more applications that replicate a Windows experience.

You can only download the Dolphin Emulator application from the Discover application that can be found on the taskbar of the Steam Deck’s Desktop Mode. So once you’ve entered the Desktop Mode simply follow these steps:

  • First, launch the Discover App from your Desktop Mode.
  • Navigate to the Search Bar
  • Enter “Dolphin Emulator” into the Search Bar
  • Press Enter and Begin Searching for the Dolphin Emulator
  • The application with the Blue Dolphin icon is the Dolphin Emulator.
  • Click to Download and Install through its Application page.

The Dolphin App will now be installed onto your Steam Deck’s Desktop Mode. You can now run the Dolphin emulator while your Steam Deck is in Desktop Mode. The application will open in a new Window which will show you a multitude of options including allowing you to add and run GameCube and Wii games.

However, it will not be playable will the Gaming Mode of the Steam Deck. To add it to that mode as well there are a few more instructions that you will need to follow. So let’s discuss them, shall we?

How to Add Dolphin Emulator to Steam Deck’s Gaming Mode?

If you’re looking to add Dolphin Emulator to your Steam Deck then you will have to add it to your Steam Library as a Non-Steam Game. If you do this, you will be able to run Dolphin Emulator through the Steam Launcher on the Steam Deck Gaming Mode.

This is incredibly useful as you will not have easier access to the emulator whenever you turn your steam Deck On. This is because upon initial booting the Steam Deck always opens in Gaming Mode first, and can be switched only later.

For many people, it can be quite the hassle to constantly switch around, and it is because of this reason that if you add Dolphin to your Steam Library it will reduce the overall hoops you have to hop through to play the games that you want.

Add Dolphin Emulator as a Non-Steam Game

  • Make sure you are in Desktop Mode.
  • Open up the Steam Application – Not in Game Mode.
  • Navigate and Select the Games option on the Menu at the top
  • Click the option “Add a Non-Steam Game” from the drop-down Menu.
  • Check the Box in front of the Dolphin Emulator
  • Finally, Click the Add to program button at the end.

And voila! That’s all you needed to do to get your Dolphin Emulator to be a part of your Steam Library, and to be available on your Steam Deck’s Gaming Mode. Now you will not have to deal with any sort of hassle while trying to play your favorite GameCube game.
