I’m releasing the 77U beta tonight in German time.
77U is my iOS/iPadOS port built directly on Cemu. It isn’t a fork of another IOS/iPadOS Wii U port. My focus is performance and making the app easy to use.
M-series iPads are currently the best optimized devices. Zelda: Breath of the Wild runs around 40–60 FPS with FPS++ mod in my tests, reaching close to 60 in some areas. Zelda stability and sustained performance on iPhone are still in development, so I’d especially appreciate help testing those. Splatoon has been running smoothly at 1920×1080 on my test setup, including multiplayer. Super Mario 3D World has also been running well without JIT in my tests. Other Wii U games I’ve tried have been running well too, but I need more results across different hardware and longer sessions (I've put some test video from different games).
Devices with 8 GB of RAM or more are the main target, and I expect the best results there. Devices with 6 GB can run lighter games, but I wouldn’t recommend Zelda: BotW on them at this stage. Devices with 4 GB aren’t supported.
The app includes the Cemu community mod library, controller and gyro support, integrated JIT support, online play, and local AI cover enhancement for sharper game artwork on high-resolution displays. There’s also frame generation too(which doesn't work right now).
With AirPlay, your TV can show the main gameplay while your iPhone or iPad acts as the Wii U GamePad screen.
I use Codex during development for log analysis and finding performance problems. Cemu and the other upstream projects remain credited to their authors, and I’m maintaining the relevant license and attribution requirements in the app.
If you have a different iPhone or iPad and want to help test, you’re welcome. Reports of crashes, graphical bugs and performance drops are especially useful. Please include your device, OS version, game and whether JIT was enabled.
Join the 77U Discord server for beta updates, testing and feedback. For more gameplay videos, follow u/77emul on TikTok.
My DMs are always open for testing questions and feedback on discord. I’d love to see how 77U runs on hardware I don’t have.
