emulation

Recreating legacy hardware and software systems in software, emulation demands bit-exact or cycle-accurate fidelity across multiple target architectures. The field sits at the intersection of performance engineering, low-level optimization, and AI-assisted tooling. Practitioners work to extract meaningful gains from mature, battle-tested codebases where conventional profiling has often already captured the obvious wins.

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.
