From the README

Live Demo (bring your own ROM)

A complete rewrite of Pokemon Yellow in TypeScript, running in the browser on HTML5 Canvas.

This is not an emulator — it's a ground-up reimplementation of the original Game Boy game, ported instruction-by-instruction from the pret/pokeyellow Z80 assembly disassembly into modern TypeScript. The goal is pixel-perfect, logic-exact fidelity to the original game, including all Gen 1 bugs and quirks.

The game engine is pure TypeScript (~280KB). No game assets are included in the repository.
