This demo uses the 40x48 x 15 color graphics mode on the Apple II.
All higher res is generated by cycle-counting, beam racing, and self-modifying code. This runs on original Apple II from 1977, there is none of the later "double lo-res" or "double hi-res" involved here.

Note the Apple II has no reliable way of detecting the hblank/vblank so it uses a horrible hack to find it, then has to do an exact 6502 cycle count forever to maintain it.
