Voxel Engine

This is a stereo recording (for red-cyan glasses) of my current Voxel engine code. Solid 3D on Virtual Boy.
Fully written in v810 assembly. It runs somewhat slower on real hardware but still achieving 9 FPS and above. A possible game based on this is under discussion.
code: enthusi
levelmap: adapted from Comanche with some changes
Featuring 12 affine world maps (probably a world's first :) but in the end I will likely go for a slightly smaller view and 8 'worlds'. 13 dither shades (4 native colors including black). Some more details and a binary to play with are available here:
