A500 Doom-engine v0.05
			 --------------------------
			 by Kalsu/Artificial People

This doom-engine is indeed designed to run on a plain A500/2000. It uses a
copper screen which works on OCS, although the "pixels" are as large as 8x4!
It not only has 4096 colours, but also overscan. The speed is also quite
remarkable: 11-12 frames per second on my A2000. It will probably go faster
when I bother to convert it to pure assembly code.

The current version is an E program with an optimized assembly routine doing
the texture mapping. Everything else is done in E.

How to run Doom500
~~~~~~~~~~~~~~~~~~
- write "doom500" in a CLI, or "doom500 fog" if you want fog
- read the docs on screen and start the routine
- press ESC when you've had enough
- when you finish you'll get a frames-per-second rating
