How to port or remake a classic game with AI

Short answer: Start from something you legally own (the original game files, its assets or an open-source engine), give the coding agent one system at a time to port, and compare every step against the original running side by side. Builders below used Claude Code to port Tetris DX from the Game Boy Color to the NES in a few days, demade a Rust auto-battler into Game Boy Advance and N64 ROMs in about 2 and 3 days, rebuilt Tzar: The Burden of the Crown in Rust and Bevy with 600+ tests, had Codex port Tiberian Sun to the browser with multiplayer, and recreated Super Mario 64 for the GBA with the original movement physics. Keep notes and tests between sessions so the port doesn't drift, and don't publish copyrighted assets you don't have rights to.

Classic games people ported to new consoles, rebuilt in modern engines or remade in the browser with AI coding agents, each linked to its source. 17 matching use cases below, each with a public source.

Get started in 3 steps

Pick a target first (browser, a retro console, Godot or a native engine) and have the agent port one system at a time, such as input, physics, then rendering.
Run the original and the port side by side and give the agent exact differences, like a jump that is 2 pixels too short, instead of 'make it feel right'.
Keep a test suite and a notes file between sessions, and ship only your own code plus assets you have the rights to use.
