This is because cc65's +default atari linker script doesn't support multi-segment executables, +and it's a royal PITA to write a custom cc65 linker scripts. Also +because it makes ca65 behave more like Mac/65, which was my go-to +assembler back in the old days. + +It might be possible to optimize this a bit further, maybe shave a +few percent off the run time. drunkwalk.s contains the innermost loop, +which has been unrolled and cycle-counted. + +During generation, the ANTIC chip's DMA is disabled, to speed things +up. There wouldn't be anything to see anyway: the generation process +works with unpacked pixels (one per byte), so the ANTIC couldn't +display them properly. At the end, when all the particles are done, +the unpacked pixels are packed into bytes for display. Using unpacked +pixels is faster than doing all the shift-and-mask operations needed +for packed pixels, but it also uses a lot of memory (48K required, so +it won't run on my poor old 400). + +Packing the pixels is a slow process, takes about 0.6 seconds. Since +it happens only once at the end of a 3+ minute process, it's probably +not worth trying to optimize. See render.s.
