GPT-6 reverse-engineers The Simpsons: Hit & Run into an open-source playable web game
CtrlAltDwayne · x · 2026-09-07
Developer @CtrlAltDwayne used the GPT-6 Astra model on xhigh reasoning to reverse-engineer the PS2 game The Simpsons: Hit & Run and rebuild it for the web with three.js, shipping a playable free-drive demo with character levels, vehicle selection and golden-hour lighting modes.
The project is open source, with both the code and a live playable version available. The rebuild was done largely by the model itself, consuming a large share of the author's usage quota — a striking showcase of frontier-model long-horizon coding ability.
