Wii Homebrew - Sprite

Wanted to start creating sprites for the wii project, but found out it's not very straightforward...

The Wii does not have a 2D graphics/sprite engine.
The trick is to draw a polygon (square) and add a texture to this polygon. It is some kind of flat object in a 3D world (think of Paper Mario) - it is not really a sprite.

Not really sure what this means without doing some real coding. Just note down first.

After some digging, it appears there are some libs (open source project) that are aimed to provide easy image manipulation (maybe...). Still evaluating which one to start with but GRR seems more promising.
1. GX Rgb Renderer Library (GRRLib) [primary lead: uschghost]
2. libwiisprite

Also found a game sprite archive but not sure how to make use of it yet. Just tag it first.
