I think I've got a decent method for doing tracks.. Maybe..

The method goes like so.
1. Draw track onto 64x64 image.
2. Convert to string of text.
3. Add strings of track-text into sourcecode.
4. Convert string of track-text back into positions of pixels, and draw onto the buffer.
5. Drive!

Seems to work.
Next will be adding track-tracking so the game registers as you drive around the track.
