I've finally done it! With SDL, I got the Irrlicht engine to run on Wii! But, despite this, I still have many problems with it. I'm trying to use GL2GX to translate the OpenGL device in Irrlicht to GX, but, even though it compiles fine, it crashes.
I'll dig into that later.
For now, I can run Irrlicht's software renderers, but at a horrible framerate, 75% of the textures missing, and it crashes within 5-30 seconds, probably due to the memory it takes up. Only, it doesn't show the usual exception screen. It just goes blank, and I have to reset it...
If anyone can figure what this problem is by what I said, please give me your ideas. Sorry for the lack of detail, but I'm in a hurry. I'll give more detail later.
