It’s not emulation, Wii U contains Wii hardware and a version of the Wii operating system. When you start a Wii disc the console boots it as a Wii. (people generally call this virtual Wii or vWii mode)
But: the video output is known to be funky.
What are you using for N64 emulation? VC or homebrew. Wii U or vWii? I don’t think I tried N64 on my Wii U but on my real Wii there are no such issues.
Any photos?
Wii games on Wii U are known to underscan slightly. But it shouldn’t be a “small window”. If you could provide some offscreen pictures it could help us understand the issue more.
I’m glad to read that it’s not emulation, thanks to both of you.
For the N64 games I get it : it’s displayed in the 16/9 setting despite my 4:3 setting in the Wii U menu and the fact that SNES and NES games are displayed in 4:3 (that’s what fooled me). It’s VC on Wii U (pal, unfortunately).
So now I hope Wii games can be correctly displayed in full 4:3.
By the way Mario Kart 8 is fantastic on CRT, even a 14 inches 4:3, letter box, composite. 16/9 in the Wii U menu and I switch the format on my TV for correct aspect ratio and better resolution (I guess) than the letter box in 4/3 image. Anyway, sorry for all the artefacts of the capture, for real it’s pure light, HDR before HDR !
Yes, this is the best you’ll get with 16:9 content from Wii U on a 4:3 display. Enjoy!
You can get a bit better by using an HDMI to VGA adapter, setting the Wii U to output 720p, and then using a VGA monitor with picture adjust to fix the aspect ratio.
Can you please expand on that. In what way does that give better results? Sharper?
For Wii U games at least they would be at full resolution rather than down scaled to 480i.
Good point!
Cool discovery - the Wii U seemingly can burn any games downloaded to your system to DVD-RAM discs as external storage:
DVD-RAM disc manufacturing ended in May 2019, according to Wikipedia, and the games won’t boot on a Wii U which isn’t tied to the same Nintendo Account, but it’s still cool.
So crazy. Just… wow.
I wonder if it could support Zip disks at this rate.
I guess it just recognizes it as an external HDD?
Exactly
This is pretty funny!
Guessing would work with various other machines too.
I’m no longer allowed to edit the OP 
But Fatal Frame: Maiden of Black Water was announced for Switch today.
Thanks for the heads up. Edited.
Interesting that Nintendo, like with TW101, was happy to let Koei Tecmo release it on everything this time.
Still, I think Fatal Frame 5 stands to lose a lot since the Wii U GamePad was your camera in the original game, and going from Koei Tecmo ports there’s not even any gurantee that gyro controls will make it in, they definitely won’t for the Xbox and PC versions.
That said, Koei Tecmo publishing this version should also mean it retains the original content of the Japanese release.
Played one last game of Splatoon before the Wii U shutdown
Amidst my son’s trains and cars that now live on the TV unit.
Won my final ever Splatoon 1 match, hooray!
It was a great run
Chapter 2 begins!
Stay online with 3DS and Wii U.
Plugging my Wii U in tonight.
Probably should have paid attention and plugged it in last week!
I’ve been finishing up a move and mine was packed through the end. Sucks. I did grab 7th Dragon III Code VFD on 3DS though.
