This is my version of Bubble Universe for Acorn RISC OS machines.
It's written in heavily optimised, handcrafted ARM code and should run on any RISC OS machine, from an original Archimedes to a Risc PC. It even runs on a Raspberry Pi with RISC OS 5.28 installed!
This video shows it running on a 200MHz StrongARM Risc PC, where it's simulating 16384 particles at 93 frames per second in 480x352 256-colour mode.
It supports both Archimedes legacy screen modes and Risc PC mode descriptors, so you can select any resolution that your monitor and computer support, as long as you have enough video memory for 2 display buffers in that screen mode.
If you want to try it out on your own machine, you can download it here...
