FCE Ultra GX

A Nintendo Entertainment System / Famicom emulator for the Nintendo GameCube, Wii and Wii U, built on FCEUX and the shared libgui framework.

The README and CHANGELOG in the repository are the single source of truth for this project, so this wiki is only a signpost to them and holds no instructions of its own. Everything below links straight to the relevant section.

Platform Latest build
Wii / vWii FCEUltraGX-Wii.zip
GameCube FCEUltraGX-GameCube.zip
Wii U (native, Aroma) FCEUltraGX-WiiU.zip

These are rolling builds of the latest master (Nightly Builds). Tagged versions and the Wii forwarder channel installer are on the releases page. Not sure which Wii U option you want (vWii, VC-style injection or native)? See the Wii U comparison.

Install and set up

FCE Ultra GX is homebrew, so your console needs to be set up to run unsigned code first. The README walks you through it for each console:
