The full story

Stefan used Reverse Engineer Anything to pull the run and jump numbers out of Super Mario 64, checking each one twice. Claude Code then built a new 3D platformer that had to match them all. He calls it the best result he's had, and the video covers the movement mechanics, gameplay and what the project cost.

Prompt & Solder

An independent community project. Not affiliated with Anthropic.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.
