The full story

GBA DS is a Game Boy Advance emulator for dual-screen handhelds such as the Anbernic RG DS Plus, on ROCKNIX or Android. The game plays on one screen while the other shows something useful from the game itself, such as the map in the Metroidvanias, in the way the DS Castlevania games did.

Version 1.5 supports 51 games, up from seven a month earlier, each tested by hand. Racing games move their HUD to the second screen, and other games show whatever suits them best.

The developer says Claude is used in its development with a lot of human hand-holding, manual review and built-in testing, and the README carries an AI disclosure.

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). The Claude connector only receives the search words your Claude sends it.
