So, as promised in >>1, I finally got bored, and wanted to try and do some coding on the Nintendo DS, so I took a couple days to port Speed! to it, to get familiar with the hardware. It's available on the Google Code page as usual: http://code.google.com/p/speed-game/
It runs in the no$gba emulator, but since that one doesn't support hardware fog, it doesn't look as good as on the real hardware.
