Just got my own Wii U dev kit up and running today, I've been afraid to see what shaders won't be supported. Looks like BlendAdditiveVertexColor is off limits...
And I haven't gotten my build working well enough to test it myself yet, but the output mentions the Depth Mask shader being unsupported too. Do you know if that's true, unikron? If so I'm in some big trouble, I use that in so many places...
I'd wait until I get the build working myself, but I was hoping to have the Wii U version functional for a show in a few weeks, and if this is true then I might as well not bother for now since I'd have to redo/remove everything using the depth mask. If it's true, is there any way to replicate that effect without a fixed function shader? I'm helpless at writing my own...
