snes9x

A widely used open-source Super Nintendo emulator, this project has a stable, performance-sensitive codebase that serves as a subject for AI-driven optimization research. Content here covers profiling, low-level tuning, and automated iteration applied across x86-64 and arm64 targets, with correctness validated to the bit. The underlying argument: mature emulation code holds significant headroom that modern automated tooling can unlock at low cost.

Vast dark silicon landscape with nearly all CPU cores dormant, visualizing wasted compute sitting idle in existing hardware.

The Cheapest Compute on Earth Is the Compute You're Already Wasting

An AI-driven iteration loop made the Snes9x emulator 61% faster on x86-64 and 52% faster on arm64 in three days for under $30, with every frame and audio sample bit-exact against the original. The argument: the cheapest performance gain is the compute already wasted in mature code.
