This guide requires that you have already set up SPFN on your Wii U and created an account. Account creation is currently unavailable on this website. If you have not done this yet, [follow this guide](/guides?guide=install-wiiu)
You will also need to dump your SPFN account and `otp.bin` and `seeprom.bin`files from your Wii U. Follow Cemu's [guide to dump online files](https://cemu.cfw.guide/using-dumpling.html#online-files) and dump your SPFN account. Take this time to also dump your Splatoon game if you haven't already done so.
Transfer the dumped files to your computer.

### Step 2: Cemu Configuration
Make sure you are using the latest version of Cemu. This can be found [here](https://github.com/cemu-project/Cemu/releases).
Open Cemu and go to `File -> Open Cemu Folder`. Place the dumped `mlc01` folder, the `otp.bin` file and the `seeprom.bin` file into the Cemu folder.
You should see the option to switch to Custom network services. Select this. If you can't select it, you haven't added the `network_services.xml` file correctly.
You are now ready to play on the Splatfestival Network! [Join the Discord](https://discord.gg/grMSxZf) for information about upcoming or active Splatfests and other updates.
