Very annoying that Nintendo never fixed this bug

[Subtle Demise]

It affects exactly one batch of chips in the early days of the console, newer consoles are unaffected (so as ChibiMofo said: It's just around 1% of consoles having this bug, most likely more like 0.001% or less) and Nintendo RMAed affected consoles even after guarantee time. How exactly do you call that "never fixed this bug" ?

Is there a way to tell if your system is affected? I've been switching on and running and playing my Wii U for a while every so often just to make sure the NAND doesn't kill itself..

This thread (and bug) has nothing to do with unreliable flash chips.
That thumbnail really needs to be changed.

Oh damn. I thought that's what this was about too. Oops.

Well you don't exactly fix a hardware issue on older units. The issue was corrected with later consoles.

It was never fixed. Where did you get your info from?

I have an American Wii U with component cables, I might try later to see if it happens here, but I have to find where I had put those cables though. It's also a launch unit from 2012.

To my knowledge only PAL Wii U consoles were affected.

Well another big thing here though is that you changed a setting on the Wii U menu. The settings there are completely separate from the vWii. It is an entirely different OS with it's own filesystem and everything. There is barely any connection between the two past controllers.

What do you mean “changed a setting”?
The only thing I changed was setting the resolution to 720p.
The results are the same regardless if you set it to 480p.

I was pointing out that the resolution changing when booting into vWii is normal. That is how it was intended to function.

I can confirm that my unit is capable of displaying progressive over component.

Yeah, seems it's a bug with PAL units. It's weird that region changing it doesn't fix it... I'm having a hard time seeing this as a hardware issue, aside EEPROM saying your Wii U is PAL or NTSC, and maybe some SLC setting? Hardware should be the same across regions I believe.

Also, it's possible that your unit is rendering progressive internally, but outputting interlaced content.

For example, I'm setting here for interlaced video while my Wii U is still doing 720p, it doesn't go into 720i. But I know it's interlaced because my resolution gets cutted, stuff pixelates a bit when DMCU has to deinterlace.

You can try priiloader and access the vWii settings, it will not change DMCU so it will still display whatever you already got, but you can control at least how it behaves internally.

Edit:

Funnily enough, if I set the console to 480i... vWii always render at 480p, same if I set 1080i...

Yeah so the question is, if the Wii U side is doing the resolution switching, then the issue should be on the Wii U software, and not within vWii. The question is if it would be fixed when switching the Wii U region to NTSC? In theory I can't see why it would fix it. After all changing the region within vWii to NTSC didn't solve the issue. I was pretty sure that it would fix it but it didn't. Hence my theory that the issue must be on the Wii U side.
I haven't seen anyone change their Wii U region from PAL to NTSC. If anyone have done that I'm curious to see if it also affects this issue.

Assuming your vWii works like mine's, then you should be getting progressive over component, it's just that the DMCU is wrongly configured and for some reason it switchs to interlaced.

Region changing the Wii U may help in the sense that maybe the Wii U side will behave like American units, and will stop doing the switch. But I don't fully know the internal working of the Wii U, so you can only try. I read on WiiUBrew that OSv0 (the OS that enables Wii Mode) checks something on the EEPROM? I know that region is also stored there, so there is a chance that even region changing will not fix it, but I could be wrong

But you are running a NTSC Wii U right?
It was mentioned back in 2012 that it only affected PAL consoles. https://www.eurogamer.net/digitalfoundry-wii-u-backwards-compatibility-analysis

Ah, now that I read the article, it's true. I heard someone said that they didn't really test on a NTSC console, but seems that was wrong.

Hence why I wrote that I have yet to see anyone with a Pal console not having this issue.

Its not a bug. Its defective chips. big difference. Those that cant see the difference... ah never mind ill offend someone....

If it’s a defective chip it’s even more concerning since they didn’t fix it in the revision updates.

They solved the problem by not using hynix branded 32gb nands. Nintendo was not gonna do a recall as it would have cost them even more money as they were already hurting with the low wii u sales. so they fixed the ones that were sent in by users. The problem appeared when smash bros 3 came out because users started using their wii Us again. Remember the smash bros data corruption so called bug? It was probably never a bug but those consoles with band nands.
