IMO, the raycasting isn't the big problem (that part isn't bad really) I
have a customized routine in Basic that could be ported to 6502 (you'd
just need a few tables). The output is wall heights, so it uses a little
memory. I think there are plenty of cycles to handle it, tho.
The problem (at least for me) would be drawing the screen. I'm guessing
that midline color changes would severely limit the horizontal
resolution.. so it would have to be some kind of Stell-A-Sketch thing
with monochrome patterns to simulate shades of color. Please correct me
if I'm wrong tho, hopefully I am!
What is the highest horizontal resolution that can be achieved with either
patterns or solid lines of different colors? Can the 48 pixel wide (6
digit score) routine be stretched to fit the screen?

p.s. If anyone is interested in that Basic "DOOM" program just let me
know.. it's a small file.
