Decaf emulator for Android


Decaf emulator is an open source experimental software to emulate Wii U applications on Android OS device.

It is written in Java by Decaf Emu Team with portability in mind, with builds actively maintained for smartphone and tablet.

At this point Decaf emulator can already be considered highly optimized and possible future optimizations will only arrive in small and incremental steps.

Decaf is already able to run some commercial Wii U games, so it’s great if you’re looking to play Wii u games.

However, at this moment, you are likely to run into an assortment of graphical issues and severe bugs.

Decaf emulator is very much in the experimental stage, but Decaf has made quick progress in just a few short months.

In order to connect to official servers some system files must be dumped from a Wii U.

Currently the DRC (GamePad), Pro Controller and Classic Controller is emulated.

Wiimotes are emulated as well (including native support).

Keyboard input + USB controllers as input devices are supported and GamePad touch input can be controlled via left mouse click.

Gyro functionality is emulated with limitations and can be controlled via right mouse button.

Keep in mind that emulation always comes with overhead and requires a higher performance system than the emulated system.

  • CPU: quad-core 2.5+ GHz
  • RAM: 6 GB minimim (8 GB recommended)
  • OS: Android 8 (or above)
  • Storage: 32 MB minimum

For Decaf, the single core performance of your CPU (and by extension RAM speed) is the most important factor for fullspeed emulation.
