Decaf is another Wii U emulator that is open-source. While there have been more attempts to port Decaf to ARM environments, it still lacks the optimization and compatibility layer that makes Cemu the gold standard. The Future: Impact of DMA and EU Regulations
), replicating this complex architecture on mobile required significant optimization and the evolution of Apple's silicon (M-series and A-series chips) to handle the workload. Cemu on your device or which file formats are best for performance? CEMU: Wii U Emulation Has Finally Reached iOS Devices
Pair the app with your computer, enter "Big Picture Mode" remotely, and boot Cemu. Alternative Emulators Native to iOS
Assuming you have sideloaded a compatibility layer (like the Sudachi modded core in or a standalone WiiU4iOS build), here is the current performance landscape on an iPhone 15 Pro / iPad Pro M4 :
Modern Apple Silicon (A-series and M-series chips) is powerful enough to handle the emulation of the Wii U's PowerPC-based architecture. How to Set Up Cemu on iOS (2026 Update) Cemu Wii U Emulator Ios

Place your keys.txt in the designated folder within the app data structure.
The good news is that, for the first time, a technical proof-of-concept exists. As iPads and iPhones continue to get more powerful, and as developers find new ways to bypass Apple’s JIT restrictions, Cemu on iOS could eventually become a reality. For now, if you want to play Breath of the Wild on a tablet, an iPad running Cemu remains a glimpse into the future rather than a concrete solution.
Ensure Vulkan is selected. iOS utilizes MoltenVK behind the scenes to map Vulkan calls directly to Apple's native Metal API. Cemu on your device or which file formats

(using Moonlight or Steam Link to stream Cemu from a PC) rather than running it natively. Conclusion
Unlike the Nintendo emulator Delta , which is easily available on the App Store, Cemu faces hurdles due to Apple's strict policies on JIT (Just-In-Time) compilation, which emulators rely on for speed.
Early builds have demonstrated titles like Captain Toad: Treasure Tracker and Super Mario 3D World booting on high-end hardware like the iPhone 17 Pro .
