Known Issues

Please note that the Wii U Emulator Cemu does not display Undertale properly. Due to the way the Nintendo Web Framework renders games, the graphics appear corrupted or invisible in the emulator. However, the game displays perfectly on real Wii U hardware.

Before - Cemu Glitch
Loading undertale on cemu
After - Real Hardware
Render glitch. crashes instantly and just shows a white screen
Legal Disclaimer
The people making this port does not support piracy in any way. In order to patch Project Echo onto your Wii U, you'll need a real copy of Undertale and the data.win file. OneShot does not apply to this because that port is using the 2014 freeware verison.

How it's Made

I use a tool called Nintendo Web Framework to bring Undertale and Deltarune to the Wii U. Because gamemaker lacks a native Wii U port, we instead export undertale to HTML, and then use Nintendo Web Framework to pack it into a Wii U File. OneShot will be based off of the EasyRPG Wii port by cmaster25. You can find their source code here: https://github.com/cmaster25/Oneshot-For-Wii

FAQ

When will this be complete?

I don't know. This project has no eta yet - but i believe it will be this year.

What about fangames (Undertale Yellow, Undertale Plus etc)

It would require complete recompilation of the NWF software as a whole to add mods and fangames. I'm interested in doing them too - but my focus is on those ports at the moment.

How can i contact you / help out with the port?

Join the discord. I plan on recruiting people who's knowledgable in the Wii U Homebrew and GameMaker scene to help. DELTARUNE in particlar has frame rate issues that i need to fix.

Do you plan on porting other games to the Wii U?

Absloutely! It may take time, however.
