Cemu

This guide will show you how to access your server from the Cemu emulator.

Connecting

With a Wii U

1. Follow the Wii U connecting guide first.
2. Follow the official Pretendo Network Cemu installation guide.
   • If you are using multiple accounts, make sure to disable the Merge Account To Default Cemu User setting in Dumpling.
3. If you have not done so already, use Dumpling to dump your Friend List system application and any online games you want to play.

Without a Wii U

warning

Prefer using the Wii U method if you have access to a Wii U console. This method is more complicated and requires using an account server patch that disables console verification, which normally blocks invalid OTP and SEEPROM dumps. The fake OTP and SEEPROM dumps will not work on the official Pretendo server.

1. Run ./scripts/create-cemu-online-files.sh --fake-dumps <pnid> to generate the necessary online files, including the account.dat and the fake dumps. Replace <pnid> with your PNID username, and enter the password when prompted.
   • If you already have another account in Cemu, you can use the --persistent-id option to change the persistent ID (like 80000001) of the generated account.dat to one that is not already in use.
2. Copy otp.bin, seeprom.bin, and mlc01 from the created online-files directory to your Cemu directory. Merge the mlc01 directory with your existing Cemu MLC directory if you have one.
3. Continue with the official Pretendo Network Cemu installation guide to enable online mode with Pretendo in the account settings.

Finally, open the settings.xml file in your Cemu data directory and set the <proxy_server> value to http://server-ip:8080, replacing server-ip with your server's IP address. Select your self-hosted PNID user in Cemu's account settings.

Test your connection by opening the Friend List and making sure it connects successfully and shows your self-hosted PNID username.
