rlm@550 18 ;; Use the gameboy's screen to display the new programming
rlm@550 19 ;; instead of a side window. This will make it look much
rlm@550 20 ;; cooler and create a terminal-like effect as the game is
rlm@550 21 ;; being reprogramed. To do this, use a fixed data entry
rlm@550 22 ;; region in ram, and run a program that translates this
rlm@550 23 ;; region into the screen. Every time this data entry region
rlm@550 24 ;; is full, run a program that copies the data to the
rlm@550 25 ;; appropriate region in memory. This will cost ~15 seconds
rlm@550 26 ;; at the beginning to set up, and then should have minimal
rlm@550 27 ;; overhead (~5%) for the rest of the data transfer, but
rlm@550 28 ;; will have a good psychological effect for the viewer
rlm@550 29 ;; since he can see that something is actually happening in
rlm@550 30 ;; the game.
