Someone gave Claude Opus 5.5 one prompt in Claude Code and over about 3 days it remade all of Pokémon Red, writing around 25,000 lines of JavaScript that draw every pixel in code, with no image files, playable in the browser. → All 151 Pokémon are built from shapes like ellipses and polygons, shaded and outlined as the game runs → The full game: 224 maps, 8 gyms, Team Rocket, the Elite Four and the Champion, with every line of dialogue rewritten → The original melodies are re-voiced in JavaScript, and bots tested it by talking to every NPC and fighting thousands of battles → It even rebuilds MissingNo. and the Mew trick, and plays on phones with Game Boy or GBA-style controls Repo: https://github.com/levy-street/pokemon-claude-red
