I've seen a game on C64 that implements a Wolfenstein-like engine. It
used both the C64's and the 1541's cpu to do this.
With a few tricks I got a "pixel-oriented"-like mode on gameboy, I
filled the display with the characters from 0-255 in a 16 by something
matrix, and then put my stuff into the font memory.
Maybe the adressing in VRAM is a problem, but we could prepare the
screen in RAM and use a block-transfer to get it displayed.
This is one of the things I wanted to try for some time, but I'm
terribly busy with work.

P.S.: I think the game was called "MOOD" or "M.O.O.D" or "Moods"... Try
AltaVista... I got it running on VICE, with 1541 emulation enabled.
