Can Wii U play Wii games in 1080P yet?

Why would it suddenly be able to do something it was never designed to do? It takes a lot more GPU power than the Wii U ever had to upscale Wii graphics beyond their 480p native resolution (as Dolphin does on modern PCs). Don't expect that to ever happen on a Wii U because it won't.

On Dolphin emulator, yes.

On a Wii U, no.

Not gonna happen. The Wii U relies on a Wii GPU for vWii and Wii VC, with its own GPU being used only for post-processing.

That post-processing can be improved with evWii, but that's all you're getting.

For all we know there might be away to start Wii and Gamecube games directly on the Wii U side just like how Nintendont loads Gamecube games through the Wii mode, that way 720p should be doable (and possibly 1080p)

You sure you don't mean uprender? Just upscaling won't use much more resources if any.

I actually do spend some time looking into the possibility of this, but it would require emulating the Wii GPU, which may or may not be feasible within WiiU limits (realistically it should be especially if given to a secondary core), but the amount of work required to figure everything out wasn't worth my time. Nintendont was only feasible because the GC and Wii share almost everything, making conversion much simpler. I didn't spend a ton of time on this though, so maybe someone that better knows GX vs GX2 better could chime in and give a better answer.

The Wii and WiiU GPU are completely different (the Wii being something R700 based and the Wii being an entirely custom fixed function GPU that contains everything the GC does plus some. The way vWii works is that the WiiU GPU has the Wii GPU embedded into it as a separate block, but that means you are limited to the exact Wii output. I don’t believe WiiU mode has access to this part of the GPU, but I may be wrong.

Also, they both use completely different APIs/ABIs. The WiiU GPU cannot understand GX (the Wii’s API), nor is it a simple conversion. Despite being called GX2, GX2 has almost nothing to do with GX. Meanwhile both GC and Wii use GX, so no translation was needed.

Despite this, this post has interested me enough to look more into this, so maybe something will come of that.
