The full story

PlumSG is a Mega Drive, Master System and Game Gear emulator built with Claude's help. Its two headline features are a per-game music editor that replays the FM and sound-chip music as General MIDI notes on a SoundFont, with sheet music, and a voxel 3D effect that extrudes a game's sprite layers.

The first beta is out on GitHub. The maker has tested many games and all the features by hand, but not the whole catalogue, and warns to expect bugs.

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.
