Hacking Does anyone has this type of specific Nintendont source?

[MaxiBash]

I've looked everywhere at this point, even the Way Back Machine.
I need a source code that has the folder nintendon-t-read-only/loader/source/data/.
It's not on GitHub, it doesn't have the source/data folder, only loader/data or just source.
I'm using this thread as a reference: https://gbatemp.net/threads/custom-nintendont-system-menu-channels-for-wii-vwii.380025/ (the first comment you see is the tutorial I use).

If there is something incorrect in this tutorial or you do have a backup of this source code, let me know!
