From Atari to Amiga: Playing Complex Chiptunes With Zero CPU

This technical breakthrough in the demo scene showcases how deep understanding of hardware architecture can overcome seemingly impossible compatibility challenges. By emulating Atari's square-wave based YM2149 chip entirely through Amiga's PCM-based PAULA chip without any CPU overhead, the author has not only won a competitive benchmark battle but opened new doors for cross-platform chiptune production. The achievement demonstrates the power of creative hardware engineering when resources are constrained.
