This video shows a stock Amiga 1200 running various visual effects using the dot-matrix engine. The effects are obtained by means of a system that allows every single pixel to be located anywhere in memory (regardless of the RAM type). Lately, I've started thinking again of a game that makes use of the dot-matrix engine, and I came up with this new system. I finally have a somewhat interesting game concept (not shown here), but I'm still thinking of better alternatives.
Technical note: while the dot-matrix engine doesn't require any CPU operation, this new system is entirely CPU-driven, so each screen update takes more or less 1.3 frames on a stock A1200; therefore, if the game eventually uses the system, it will run at most at 25 fps.
