Ray casting on turbo R

The obvious new bit in this demonstration is the walking robot in the maze. Now the code and data fit in 45K. Work needs to be done on mapper support in order to add animations (walking), and other textures. Also a simple AI is in development. How far could this concept be stretched? Would a 1chipMSX with a boosted Z80 and a Graphics9000 in one of its slots make this new effort shine like it should? Thrill and excitement await us! Now, where to find a gun to blow that piece o' walking rust to bits..

Thanks, credits have to go also (and mainly) to Wouter, who moved to asm the critical parts of the engine

PS
Obviously the answer to the emphatic question from wolf_ about 1chip and the rest is no. The code is for r800 and v9938, nothing more, nothing less.

Now walking animation takes 4 frames, there is an extra frame for standing still, so we have 5 poses. Each pose has 8 directions of view, giving thus 40 frames for the sole enemy robot.
Add 4 frames for pillars and columns and you get 44 frames in total that fill about 64K of RLE data (4 ram segments).
The textures for walls now are 9, that with the shadowing become 18, and fill about 32K of RLE data (2 ram segments).

This means that without loading, with a 256K msx turbo R, it is reasonable to have up to 3 animated enemies, about 12 items and 18 textures.
