C224

Gain an understanding of a tiny CPU and clear as many stages as you can!

You are presented with the C224, a processor with two inputs and four outputs. It has enough internal memory to store eight instructions, each chosen from among sixteen options: “RR”, “AB”, “IB”, “AZ”, “+B”, “&B”, “|B”, “^B”, “J0”, “J2”, “J4”, “J6”, “?0”, “?2”, “?4”, or “?6”. Your goal is to figure out what these instructions do, then use this knowledge to solve puzzles, where both output and timing are important.

Controls

Ctrl+M to mute.

Z/X are O/X in PICO-8, so keyboard users can use Z to edit, X to run.
