Welcome to my Citro3D Documentation! This is a collection of the notes that I've tooken while learning how to use the 3DS Citro3D library.
If you didn't know already, Citro3D is a library used to develop homebrew for the Nintendo 3DS. It provides an easy to use stateful interface to the PICA200 GPU, the GPU that the 3DS uses.
And this is a test, ignore pls.
