The guys at 2DBoy (creators of one of my favourite Wii games, World of Goo) have released part of the framework of code they used to create World of Goo.

I've not worked through much of the code yet, but there are some interesting bits and pieces to learn from. The compilation instructions are for windows, and I've only got bits of it to compile on Linux. I've noticed some references to Wii in the code, in particular in the crypto files there's some stub functions.
I couldn't see this posted to the forums already, so I thought I'd ask if anyone else is doing anything interesting with the code, and if anyone has got it to work under devkitPPC?
