Swizzle 3ds

Swizzle textures from scanline to the 3ds's gpu texture format

This is a rust version of tex3ds basically, although it has less features and is more designed to be used as a library for other things (e.g. bevy)

lib.rs:

Crate to swizzle textures for the GPU on the 3ds

An explanation of how the swizzling works can be found here also tex3ds is a great reference implementation
