This graphics mode is really creative :-) Too bad that the screen needs
to be shrinked so that all pixel data fits into 1kB screen memory.

Would it be perhaps possible to write routines that quickly copied pixel
data several times when the screen is displayed, so that the same screen
memory could be reused for different scanlines? Something like C64 VIC
tricks... Or is the 1 MHz clock too slow for that?
