Cemu, the popular Wii U emulator, has recently received a couple of new updates! Version 1.15.4 includes h264 video decoding & controller hotplugging, improves SpotPass functionality, adds OSScreen API support for the gamepad view to enhance homebrew emulation and also fixes a good number of bugs and crashes. A minor release was also unveiled shortly after, 1.15.4b, which fixes an issue with the memory searcher tool, warns the user when games are being used online with invalid or missing certificats and also includes other general stability improvements.

The full changelog is as follows:

H264: Added full h264.rpl module implementation (#25)

And Cemuhook which had its original purpose as a way to add an h264 decoder has been updated to the following:

0.5.7.1 - Do not replace H264 Decoder functions for Cemu versions >= 1.15.4 (which has native H264 decoding support), option in Debug menu to override

So you can still use cemuhook's version if you really want to or if there is problems.

HAHAHA
I see a couple of "Stability improvement"
What? CEMU think they are Nintendo???

What is OSScreen?

What is OSScreen?

In a nutshell, when developing homebrew applications on the Wii U, you have access to two graphical APIs: a low-level one that interfaces directly with the console's GPU (GX2) and a high-level one (OSScreen). The former is used in all officially licensed Wii U software and, being a low-level API, is much more powerful and complex, while the latter is way more limited but also much simpler to get started with.

While GX2 was also adopted by graphically heavy or more complex homebrew, other simpler ones still used OSScreen due to its simplicity.

Very useful answer. Thanks for this.

does CEMU support the WiiU GamePad ? or is that still not a thing yet? aka. can i finally throw my WiiU into storage? :3

 

[XDel]

The WiiU had Homebrew?!? Like DOOM and Half-Life ports?! Where?

To give you some idea.

Until it is working without the shitty shader import bullshit, i am not interested in the slightest in this emulator.
