Building

This project is assembled with BeebAsm.

BeebAsm.exe -v -i pipes.asm -do pipes.ssd -boot PIPES

Notes

• The demo uses a procedural pipe-grid generation system and a simple dissolve effect.
• The BeebAsm build target produces an SSD image called pipes.ssd.
• The demo is compatible with both the BBC Micro and Acorn Electron.
• 2D Pipes demo (https://www.pouet.net/prod.php?which=105148) for ZX Spectrum 48K by Ollibony, 1st place at Chaos Constructions 2025 - this is not a direct port.
