18 ;; Use the gameboy's screen to display the new programming
19 ;; instead of a side window. This will make it look much
20 ;; cooler and create a terminal-like effect as the game is
21 ;; being reprogramed. To do this, use a fixed data entry
22 ;; region in ram, and run a program that translates this
23 ;; region into the screen. Every time this data entry region
24 ;; is full, run a program that copies the data to the
25 ;; appropriate region in memory. This will cost ~15 seconds
26 ;; at the beginning to set up, and then should have minimal
27 ;; overhead (~5%) for the rest of the data transfer, but
28 ;; will have a good psychological effect for the viewer
29 ;; since he can see that something is actually happening in
30 ;; the game.
33 ;; Symbol size and type.
35 ;; use fonts from zophar's domain:
36 ;; http://www.zophar.net/utilities/fonts/8x8-font-archive.html
38 ;; Green font on black background for matrix look.
