Well known 3DS hacker Smealum just released iosuhax for the Wii U. This series of tools for the Wii U is described as a “kind of” Custom Firmware for the Wii U.

What is iosuhax?

Despite its name echoing the 3DS *hax series initiated by Smealum, iosuhax will not be useful for the majority of the end users though: it doesn’t include any exploit, and should for now only be considered useful for Wii U devs out there.

This release comes in the context of ongoing rumors about an upcoming Kernel Exploit release for the Wii U 5.5. This could all sound like great news, except that release is extremely uncertain at this point. Plus Smealum released his code while announcing he has no plan to work any further on the Wii U, for the time being.

Nevertheless, if you’re a hacker looking into details of the Wii U Security, iosuhax might be great for you. The readme mentions the following features:

• software nand dumping (bunch of ways to do this, dumps slc, slccmpt and mlc, either raw or filetree or something in between)
• redNAND (redirection of nand read/writes to SD card instead of actual NAND chips)
• remote shell for development and experimentation (cf wupserver and wupclient, it’s super useful)
• some basic ARM debugging stuff (guru meditation screen)
