The full story

The maker used Claude agents to translate Pokémon FireRed into Finnish and published it on romhacking.net, and a Terraria translation is in progress. Sonnet does the translation and Opus reviews it, since a review produces very few output tokens.

The maker says the agents can look around the game for context, build a glossary and keep a progress file the maker can watch.

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.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count).
