Playing ATARI music on Amiga for free!
Summary
A technical retro-computing blog post about emulating the Atari YM2149 sound chip on the Amiga's PAULA to achieve near-zero CPU usage. It covers the hardware differences, the MADMAX-style envelope technique, COPPER-based pre-generated lists, and a step-by-step approach that offloads audio processing from the 68000 while driving a sin-dots demo.
