Absolutely worth revisiting. There are a gem or two hidden in this 4kb 🤩 - rulezadded on the 2025-11-09 14:22:20
- demo Atari ST Blood by Holocaust [web]
- Yes.
No MUL, no DIV because the number of clock cycle these instructions take depend on the value of the register they deal with, and the full screen code must be exactly synchronized with the shifter, to do the 2-3 screen resolution and frequency switches at the exact same time for each scanline to open the borders.
Also a single MUL or DIV can take longer than the longest time between 2 of these shifter updates.
So yeah. This is fun.
... once you figure it out, you'll see the trick is really cool, and really just A level math/gymnastics. - isokadded on the 2025-10-27 16:36:52
