# Haxchi-Exploit
|
|
This is the continuation of Haxchi from FIX94 (initial PoC by smea).
|
|
|
|
```
|
|
haxchi is an exploit for the Nintendo DS virtual console emulator on Wii U (hachihachi).
|
|
it is possible due to "contenthax", a vulnerability in the wii u's title integrity design:
|
|
only code and critical descriptors are signed, with all other contents left at the mercy of attackers.
|
|
```
|
|
|
|
# Usage
|
|
Put a payload `code550.bin` in the root of this project.
|
|
This payload should be statically linked to 0x18000000, and is called inside a thread.
|
|
Make sure to exit this thread via `OSExitThread(0);`, afterwards the rop switches automatically to the Mii Maker.
|
|
|
|
An example payload which perform the kernel exploit can be found [here](https://github.com/wiiu-env/haxchi_payload).

# Notes
|
|
|
|
Currently this ONLY executes a given `code550.bin`, nothing usable for the end user. Only one game, no CFW, no coldboothax, nothing.
