Dev reverse-engineers PS2 Simpsons Hit & Run into a playable browser game with GPT-6 Astra

Developer CtrlAltDwayne used GPT-6 Astra (in xhigh reasoning mode, burning through a large chunk of usage quota) to reverse-engineer the PS2 game The Simpsons: Hit & Run and rebuild it for the web with three.js, shipping a playable free driving demo (with selectable characters); the project is open source. The author marvels at the model's capabilities.

Confirmed

• The whole process started from a very simple prompt: give the model a PS2 disc image (ISO) and ask it to unpack, rebuild, and port the game as a three.js web game
• The asset extraction stage has been completed: the model successfully extracted the game's graphical assets and began rebuilding them
• Most of the work was done autonomously by the AI, with only minimal human intervention from the author
• The project is open source, playable in the browser, with a free driving demo and selectable characters
• The model used was GPT-6 Astra at the xhigh reasoning tier; the author says it consumed a large amount of quota

Unconfirmed

• Whether a full port (all game content and gameplay) can ultimately be finished remains uncertain; current results are mainly limited to asset extraction and the driving demo

Why it matters

• This is a striking end-to-end demonstration of AI coding capability: from a binary game image to a playable web version, spanning reverse engineering, asset parsing, and 3D reconstruction
• It also raises potential questions about copyright and the boundaries of redistributing game assets (not elaborated in the post, but open-sourcing rebuilt assets from a PS2 game carries such risks)
