is there a Ultimate WiiU guide for 2023?

[V10lator]

all I see is flame here, pathetic

Cause you're not looking into the correct places. Just today there was a developer unable to debug his own tool thanks to IOSU exploits (which is what HBL Channel does, too, and why you should not use it). See:

But yea, all just flame without any evidence, right?

Where did it switch to?

NUSspli (Lite).

Please show me exactly where it is so obvious?

Please show me where I said it is obvious but anyway, just look at the last commit on GitHub. From what time was it? Around 10 years ago? So you trust software using methods which are outdated/obsolete since 10 years and never ever saw a bugfix in that time?

that was not even updated since 2019 LOL

There you say it for yourself: WUP Installer is abandonware. So why are you still using it?

Lastly keep in mind that I said "is in the process of switching", not "switched away". My point was that these YT videos slow down said process a lot.
