Hacking UStealth - Wii U 'Format Disk' Nag workaround :)

[AskingForTrouble]

I'm wondering the same thing. I want to partition my hard drive into two formats, one for Wii U and one for vWii. Did you ever figure this out?

At present, the Wii U drive must be fully formated to be used and doesn't support partitioning at all.

If you double-partition the drive on PC, the Wii U will still format the full drive (and destroy both partitions) before it can be used.

If you partition the drive on Wii U first and then try to partition it on your PC, the PC will not be able to read the drive at all until it's formatted for use on Windows / Mac / Linux, destroying the partition made by the Wii U.

Best way is to have two separate drives, even if one or both drives are high-capacity USB sticks, plus some additional software on SD Card(s) to be launched through Loadiine.

Ah that's unfortunate. Thanks for the info, I appreciate it.

Is anyone still using this software in 2025?

There is an updated version on the Microsoft Store for windows without the legacy dotnet framework dependency called "U-Stealth" based off the original.

If you're interested but don't want to use the Microsoft Store or want a version for another OS...

Updated Version:
https://apps.microsoft.com/detail/9pp5qm8rk8xq?hl=en-us&gl=AU&ocid=pdpshare

CLI Version:
https://apps.microsoft.com/detail/9p1txw2r0r4t?hl=en-us&gl=AU&ocid=pdpshare
(Works with win11 sudo too)

To add to what @freaky_beeky posted. Linux has a cli version, with a macos version being in the works

Is UStealth even necessary? I thought with Aroma or isfshax patches this isn't necessary. Genuine question because I'm updating my setups.

 

[freaky_beeky]

I'm still running tiramisu on my wii u, so can't speak for Aroma.
I'm going to get another wii u to give it a go in the future though, so will let post back for certain but it won't be for a few weeks at least.

Works perfectly in my use case.
SSD for the Wii U, USB (hidden) for the vWii.
