5.4.0/5.5.0 MP4 Exploit

(51 votes)

- Info -
With this you can build (and in theory, run) homebrew for Wii U version 5.4.0 and 5.5.0. It is incredibly bad, and likely won't run any code for you whatsoever. Sounds good right? Yeah? Right on!

- For Developers -
We have been incredibly lazy about fixing this. However, I have a hint for you. Use the code spray code from previous HTML exploits, and embed the MP4 exploit to run code that way.

In template540 and template550, at offset 0x79 to 0x7C contains the value that is in r30 when it crashes, which is an address to a point in the ROP buffer. Essentially leave the rest of the MP4 file unchanged if you plan on doing it via HTML/JS. If you want to use another ROP gadget, then the address that is spammed at the end of the file is the gadget that we initially jump to.
