Installing games on Dolphin means copying game files to your computer and pointing the emulator to them

Dolphin is an emulator that runs Nintendo GameCube and Wii games on your PC. To play a game, you need two things: the Dolphin software itself (which you read and install like any other program) and a game file, which you obtain separately. Dolphin does not come with games built in — you add them by telling the emulator where your game files are stored on your hard drive.

The process has three main steps: install Dolphin, obtain your game files, and configure Dolphin to find them. This guide covers the technical steps; obtaining legal game files is your responsibility.

Key Takeaways

  • read Dolphin from the official website (dolphin-emu.org), install it like any Windows program, and run it once to create its default folders.
  • Game files must be in a format Dolphin recognizes — typically ISO, GCM, or WBFS — and placed in a folder on your hard drive.
  • Open Dolphin, go to Config > Paths, and add the folder containing your game files so Dolphin can find and display them.
  • Once Dolphin sees your games in its library, double-click any title to launch it; you can adjust graphics and controller settings before or during play.

read and install Dolphin on Windows

Visit dolphin-emu.org and click the read button for Windows. You will get a .exe installer file. Run it and follow the standard installation steps — choose your install location (the default is fine), and let it finish. The installer will create a Dolphin folder in your Program Files directory and a shortcut on your desktop or Start menu.

Launch Dolphin once after installation. It will create a hidden folder called .dolphin-emu in your user directory (usually C:\Users\YourName\). This folder holds your settings, controller configurations, and save files. You do not need to touch it directly, but knowing it exists helps if you ever need to back up your progress or move Dolphin to another computer.

Prepare your game files in the correct format

Dolphin reads game files in specific formats. The most common are ISO (a disc image file, usually 1.4 to 4.7 GB per game), GCM (GameCube Master, functionally identical to ISO), and WBFS (a compressed format that takes less hard drive space). If your game file has a different extension — like .ciso or .rvz — Dolphin can still read it, but ISO and GCM are the standard.

Create a dedicated folder on your hard drive for your games. For example, make a folder called "GameCube Games" or "Wii Games" in your Documents folder or on a secondary drive if you have one. Game files are large, so if you plan to store many, put them on a drive with plenty of free space. Copy or move your game files into this folder. Dolphin will scan this folder and display every game it finds.

Add your game folder to Dolphin's library

Open Dolphin and look at the menu bar. Click Config (or Options depending on your Dolphin version), then select Paths. A window will open showing your current game library paths — it may be empty or show a default folder.

Click the Add button and navigate to the folder where you stored your game files. Select it and click Open. Dolphin will add that path to its list. You can add multiple folders if your games are spread across different locations. Once you have added your folder, close the Paths window. Dolphin will scan the folder and display all recognized games in its main library view.

Launch a game and adjust settings

In the Dolphin main window, you should now see your games listed with cover art (if Dolphin can find artwork online). Double-click any game to launch it. The game will start in a new window. On first launch, you may see a message about shader compilation — this is normal and takes a few seconds as Dolphin prepares graphics for your specific GPU.

Before or after launching a game, you can adjust settings. Go to Config > Graphics to change resolution, anti-aliasing, and other visual options. Go to Config > Controller to map your keyboard, gamepad, or other input device to GameCube or Wii controls. Most modern gamepads (like Xbox or PlayStation controllers) work out of the box if you plug them in before opening Dolphin.

Troubleshoot if games do not appear in your library

If you added a folder but Dolphin is not showing your games, first check that your game files are actually in that folder — use Windows File Explorer to confirm. Then go back to Config > Paths and verify the path is listed correctly. If it is, click the folder path and then click Refresh (or close and reopen Dolphin) to force a rescan.

If Dolphin still does not find your games, the files may be in an unsupported format. Dolphin displays a warning in its log if it encounters a file it cannot read. You can view the log by going to Tools > Show Log. If your game file is in a format like .rar or .zip, you must extract it first — Dolphin cannot read compressed archives. If you are unsure whether a file is valid, try right-clicking it in Dolphin and selecting Open Containing Folder to inspect the file directly.

Save your progress and manage game data

When you play a game in Dolphin, your save files are stored in the .dolphin-emu folder automatically — you do not need to do anything. If you want to back up your saves, go to Tools > Memory Card Manager (for GameCube saves) or Tools > Wii Save Manager (for Wii saves). From there you can export your saves to a backup file on your desktop or external drive.

If you want to move your Dolphin setup to another computer or reinstall Windows, you can copy the entire .dolphin-emu folder to preserve all your settings, controller mappings, and save files. This folder is hidden by default in Windows, so you will need to enable "Show hidden files" in File Explorer options before you can see it.

Frequently Asked Questions

Do I need a powerful PC to run Dolphin?

Dolphin runs on modest hardware, but performance depends on the game and your graphics settings. A PC from the last five years with a mid-range GPU will handle most games at 1080p and 60 frames per second. Very demanding games or high resolution settings may require a newer or more powerful machine. You can always lower graphics settings if a game runs slowly.

Can I use a wireless controller with Dolphin?

Yes. Most modern wireless gamepads (Xbox, PlayStation, or generic USB controllers) work with Dolphin if you plug in the receiver or connect via Bluetooth before opening the emulator. Go to Config > Controller to map the buttons. Some games, especially Wii titles, may require a real Wii Remote for motion controls — Dolphin can support this with additional setup, but a standard gamepad works for most games.

What if a game crashes or runs slowly?

First, try lowering graphics settings in Config > Graphics — reduce resolution, disable anti-aliasing, or switch to OpenGL instead of Vulkan. Some games have known compatibility issues documented on the Dolphin website. Check the game's page on dolphin-emu.org for reported problems and suggested settings. If a game consistently crashes at the same point, it may have a compatibility issue that cannot be fixed without a Dolphin update.

Can I play online multiplayer games in Dolphin?

Online play in Dolphin is limited and experimental. Most games that required Nintendo's online servers no longer connect because those servers are offline. Some games support local multiplayer (multiple controllers on one PC), which works fine in Dolphin. Check the game's compatibility page on dolphin-emu.org to see whether online or local multiplayer is supported.
