This guide provides comprehensive instructions for setting up and using Dolphin UWP, the GameCube and Wii emulator, on an Xbox Series S/X in Developer Mode. It covers initial setup, file transfers, Netplay, optional resources (saves, cheats, textures), troubleshooting, and advanced topics.
Important Notices (Read Before Proceeding):
- Read the Guides: Before asking for help, thoroughly read the
#dev-mode-guide
channel (presumably in a Discord server) and the USB tutorial in #app-guides
if using USB storage. If you're still stuck, ask for help in #support
.
- Dolphin PC is Recommended: Think of the PC version of Dolphin as an extended settings menu for Dolphin UWP. While not strictly required, Dolphin PC is extremely useful (and sometimes necessary) for many features and configurations. This guide assumes basic familiarity with Dolphin PC. A powerful PC is not required for this.
This method uses a USB drive for storing games and Dolphin's user data.
- Open Dolphin Settings: On your Xbox, launch Dolphin UWP. Press the Select/View button on your controller to open the Dolphin settings menu.
- Add Game Path: Select "Add Path".
- Choose Game Location: Navigate to where your games are stored on your USB drive. The guide suggests the following structure:
E:\Games\Nintendo - GameCube
E:\Games\Nintendo - Wii
The User Folder is where Dolphin stores important files like:
- Texture Packs
- Controller Configurations
- AR/Gecko Codes (Cheats)
- Box Art
-
Create Dolphin Folder: On your USB drive, create a folder at the root level (e.g., E:\
) named Dolphin
.
-
Open Dolphin Settings: Launch Dolphin UWP and press Select/View to open the settings.
-
Set User Folder Path: Go to "Paths & Folders" > "Add Path" and select the Dolphin
folder you just created.
-
Automatic Folder Creation: The first time you launch a game, Dolphin will automatically create its necessary subfolders (like Load
, Config
, GC
, Wii
) inside the User Folder you specified.
WARNING: Using internal storage is strongly discouraged due to its limitations (30GB) and the risk of undeletable files if the app is uninstalled incorrectly (requiring a factory reset). However, if you don't have a Windows PC to format a USB drive, this is your only option.
-
Connect via FTP: Use Durango FTP (see #app-guides
for instructions) to connect to your Xbox from your PC.
-
Create Game Folder: Navigate to: LocalFolder\[FULLNAME]\LocalCache
. Replace [FULLNAME]
with the actual full name of the Dolphin UWP application folder (see "How to find the FULLNAME of Dolphin" below). Inside LocalCache
, create a new folder to store your games.
-
Add Games: Copy your game files into the folder you just created.
-
Set Game Path in Dolphin: Launch Dolphin UWP, press Select/View, select "Add Path", and choose the folder where you placed your games.
-
Create Dolphin Folder: Using Durango FTP, navigate to LocalFolder\[FULLNAME]\LocalCache
. Create a new folder named Dolphin
.
-
Set User Folder Path: Launch Dolphin UWP, press Select/View, go to "Paths & Folders" > "Add Path", and choose the Dolphin
folder you just created.
-
Automatic Folder Creation: Dolphin will automatically create its subfolders inside this Dolphin
folder.
- On Xbox: Press the Start button on the Dolphin UWP application icon in your Xbox dashboard.
- Manage Game: Choose "Manage games and add-ons".
- File Info: Select "File Info".
- Full Name: The full name of the application folder will be displayed at the top. Use this name when navigating via FTP or a file explorer.
LOCALFOLDER
: Lists all UWP application folders that allow file interaction (e.g., RetroArch, Minecraft).
D:\
:
- Retail Mode: This is your USB drive.
- Dev Mode: This is where applications are installed (e.g., RetroArch cores).
E:\
: This is your USB drive in Dev Mode.
See the DurangoFTP Guide in #app-guides
for detailed file transfer instructions.
This is highly recommended for easier configuration.
- Add Game Paths on PC: On your PC, add paths to your games in Dolphin PC.
- Dolphin Wiki: Right-click each game in Dolphin PC and view its page on the Dolphin Wiki for game-specific information and settings.
- Properties (PC): Right-click a game and click "Properties" to apply changes like Gecko/AR codes.
- Open User Folder (PC): Go to File > Open User Folder in Dolphin PC.
- Copy Files: Copy any files or folders you want (e.g.,
Config
, GameSettings
, GC
, Wii
) from the Dolphin PC User Folder to the Dolphin UWP User Folder on your Xbox (either on your USB drive or via FTP to the internal storage).
Android and iOS don't natively support writing to NTFS-formatted drives (required for Xbox USB emulation).
- Use FTP: Use Durango FTP on your Xbox and an FTP client app on your mobile device.
- MiXplorer (Recommended): The guide recommends MiXplorer for Android (free, supports FTP).
Netplay allows online multiplayer for GameCube and Wii games with local multiplayer modes.
- GameCube Netplay: Generally stable.
- Wii Netplay: More experimental and temperamental.
- Same Game: All players must have the same game on their game list.
- Low Bandwidth: Bandwidth requirements are low, but latency (ping) is crucial. Ethernet is recommended over Wi-Fi.
- Identical Game Copies: Each player needs their own copy of the game, with matching region and revision. Identical dumps are strongly recommended. Most compressed formats work with standard ISOs (except NKit).
- Same Dolphin Version: All players must use the same Dolphin version. Newer versions are better.
- Open Netplay Menu: In Dolphin UWP on your Xbox, go to the "Net-play" menu.
- Host or Join: Choose "Host" or "Join".
-
Host Options:
- Direct Connection: Requires port forwarding on your router.
- Traversal Server (Recommended): Avoids port forwarding and uses a code for joining.
- Port: Select a specific port (if using Direct Connection).
- Name: Set a name to identify yourself.
-
Best Host: The player with the best internet connection and (for 3+ players) the most central geographic location makes the best host.
-
NAT: Players with strict NAT may need to manually port forward, even when joining.
-
Port Forwarding: Instructions vary by router. You'll need admin access to your router.
-
Host Menu: After selecting a game and hosting method, you'll enter the host Netplay menu.
- Traversal Code: If using the Traversal Server, you'll get a code to share with other players.
- IP and Port: If using Direct Connection, you'll need to share your public IP address and port.
Notes:
- Multiple Routers: Can cause complications. You might need to manually find your public IP.
- Mixed Connection Types: You can host on the Traversal Server but allow trusted users (e.g., on your LAN) to connect directly using your IP and port.
- Traversal Server Latency: The Traversal Server does not add latency; it's only for connecting.
- Host Responsibilities: The host configures the input buffer, enables/disables features, and assigns controllers.
- Set Name: Enter the name you want to use.
- Enter Code or IP:
- Traversal Code: Enter the code provided by the host.
- IP Address and Port: Enter the host's IP address and port (for Direct Connection).
- Wait: Wait for the host to start the game.
- Strict NAT: The Traversal Server may not work. The host must port forward, and clients must use Direct Connection.
- Version Incompatibilities: Older Dolphin builds might not warn about incompatible versions. Newer builds have an error message.
Port Forwarding: Consult a guide specific to your router model.
The host can adjust these settings before starting the game:
- Buffer: The amount of latency added to inputs. Increase if you experience slowdown or stuttering, even in low-impact scenes. A general formula: 1 pad buffer per 15ms of latency per client.
- Strict Settings Sync: More aggressively synchronizes settings (e.g., Internal Resolution). Use if you have a desync with an unknown cause.
- Saves on Netplay: GameCube and Wii saves now work on Netplay, the host's local saves will be used.
- Mismatched ISOs: The most common cause. Ensure all players have identical game dumps.
- Slow Internet: Low bandwidth or high latency can cause desyncs.
- Mismatched SD Card: If a game requires an SD card, all players must have identical SD card files.
- Version Check: To see the Dolphin UWP version compared to the PC version, check the settings tab in Dolphin UWP or the GitHub releases page.
- Xbox Emulation Hub Discord: The best place for pre-configured resources is the
#resources
channel in the Xbox Emulation Hub Discord server.
- Dolphin Wiki: For games without listed resources, check the game's page on the Dolphin Wiki.
