If you want to start developing Homebrew for 5.5.0/5.5.1, this guide is the guide you were looking for!

Compiling homebrew for 5.5.0/5.5.1 is a bit different, than compiling for 5.3.2 or lower.

Setup :

• Install Cygwin
• Python (2 or 3)
• DevkitPro (with DevkitPPC)
• Download my fork of libwiiu. https://github.com/TheJosamilu/libwiiu (Made a pull request for the main branch) And extract it somewhere.

Building :

Before you can actually build something, you have to compile libwiiu. For that, open Cygwin and 'cd' into the extracted 'libwiiu' folder, and then in the other 'libwiiu' folder. When you are in there, you can compile libwiiu with the 'make' command.
After that is done, you can compile some examples. The easiest to compile is the Hello World example, so cd into the 'examples' folder, then the 'helloworld' one and run 'make'. If everything goes right, you can go into the /bin/ folder and you should see your code550.bin now.
Congratulations, you just compiled your first 5.5.0/5.5.1 payload!

You can't compile the 5.5.0/5.5.1 payloads using build.py, because it is only for 5.3.2 or older.

Running :

Now, to run the payload, you need to host the Browserhax somewhere. Either you have your own website, where you can upload it at, or you host a local webserver on your computer. Grab the 'wiiuhaxx.zip' I attached at the bottom of the post, and host the contents of it on the webserver. Then copy the code550.bin over to the directory of browserhax. Now, you have to edit the cfg file to match your setup.

Code:

<?php

$wiiuhaxxcfg_payloadfilepath = "url of the payload";
$wiiuhaxxcfg_loaderfilepath = "url of the loader";

?>

Now get your Wii U ready, and open the .php page like this : wiiuhaxx.php?sysver=550
PHP has to be enabled on your webserver to work!

If you have done everything correctly, your compiled payload should load and run!
If the videoplayer has frozen on your gamepad, you did a mistake. Try it again or recompile the payload. If it still not works reset the Wii U Browser.

Conversion into mp4 :

The conversion into a simpler to use .mp4 is easy. Just load up the exploit page, with your parameter, using your computer and save the video to your computer. You can do this by pressing CTRL+S.


That's all, I hoped I help you! If you have any questions or trouble getting your payloads working, ask bellow.
