The full story

Admiral Yi: The Imjin War is a historical real-time strategy game set in Korea in 1592, made by a solo developer in Korea. The latest update adds destructible castle walls to siege battles: Joseon cannons batter a fortress until part of the wall collapses, opening a new route for soldiers to charge through.

The developer uses Claude Code and Codex for programming; the footage is captured from the game itself.

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.

Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count). The Claude connector only receives the search words your Claude sends it.
