The full story

Kotaku reports that in the weeks after Claude Opus 5.5's release, hundreds of AI-decompiled games appeared as browser ports almost overnight, including Halo: CE, GTA: Vice City, Call of Duty: Black Ops, The Simpsons: Hit & Run and Skate 3, many of which seem to work well. The article's tone is uneasy: work that used to take decompilers months now happens very fast, which raises obvious questions about copyright and what happens next.

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.
