Well, kinda but kinda not. You could use Linux on Wii U but Fortnite isn't officially supported so you would have to install winehq, Linux on Wii U's performance isn't that good so you shouldn't expect much
Today in history (I usually skip it because it is boring and I moderate the roblox hacking discord server or browse r/holup, way more pog than world war 11) my history teacher said we would be learning about China! I quickly got out my of seat and yelled “JOHN XIAN IS SO WHOLESOME!!” And my friend Pablo (aka DarkShadowKid~) stood up and yelled “+5 SOCIAL CREDIT”. I quickly pulled up my iPhone 8 and played the red sun in the sky song. But my frcking teacher took my phone !! -8 social credit, so not pog. If my teacher was in my discord server I would demote him to muted and probably would kick him 👁👁! Me and my friend sat down in rage as our teacher started out lesson. Then when I looked up at the project I almost lost my shit…IT SAID 1989!! NOTHING. HAPPENED. IN. 1989. . I quickly got up and said to my teacher “YOU HAVE -9999999999999999” and pulled out my sks. I nodded to my friend Pablo and he stood up and took out his M1911 and said “YOUR EXECUTION DATE IS TODAY, NOT POG” we opened fire, blood sprayed and flies and went all over the wall. His head hit his keyboard and the sound reminded me of the vine boom sound effect . The fake baby yodas started screaming and going everywhere. I am currently in a holding cell typing this with a slim Jim
Please, don't believe even to Flying Elephant.
There are many reasons because of that, except the technical reasons that I'm not going in details; but he said (in his posts) that he use "the mobile graphics version" what does mean Android/ iOS based?
Even that, so, he need to emulate the ARM Architecture, but he translate the custom engine graphics to AMD, and for the Anticheats, also he said to run in a Virtual Environment....WTF it's mean?!
He run an Android emulator, ok the CPU RISC PowerPC to ARM he use the layer techniques?! But how you let interface the GPU Engine if the game run on an emulation environment?!
So, first you need to implement the emulation environment, after use the technique of GPU passthrough to get the full graphic power engine and translate those instructions from mobile ARM to AMD Wii U GPU. Because if you don't use the Passthrough GPU on an Emulator the Emulator as the limits of the GPU Power and you must to use the Passthrough. Or it's fully the technique like WINE for Linux?!
Now, have means that he doesn't implemented just the game , but also the Layout Emulator, and the obstacles of the Anticheat that it's the most difficult even for a Linux user to run such Windows based games, as they are blocked by it.
Also, why he doesn't shows the Video, from the Menu , to boot the game, because maybe there you can understand something...?
Also, why it displays the Windows/Xbox colour buttons when he goes to the menu?
Also, why 600p at 20fps (as he said) instead of at least 854x480p that he can run at fully 30fps, as he shows just the PAD Wii U running.
If you want I can show you how I play with Dreamcast games in my Wii U at fully native render, and even my dumped Switch Mario Odyssey....
