That is just incredible, and close to insane.. having somthing like this running mostly 25fps on a plain A500 would have been regarded as "magic" 25 years ago.

OT: I've coded my own nontextured wallrender hacked into your "framework", it's not using unrolled loops per se, and is dog slow (worst case is over 4 frames). but it was just for learning purpose, and it's all starting to make a lot more sence now.

next up is writing my own raycaster, which is mostly done in psydo code atm. but hopefully i will have some time this weekend to try it out in Assembler.

If your thinking about my question regarding the segmented chunkybuffer, then it's only segmented for every 4 pixel on X, not on Y. sorry if my question was not explanatory enough.
