The full story

The maker of ppu.toys, a free browser studio for Super Nintendo development, connected it to Claude Fable 5.2 through an MCP server and gave it one open-ended prompt with no follow-ups. About four and a half hours and $72 later it had made Emberwake, an action platformer with five realms and five bosses that runs at 60 fps on real hardware. Unprompted, it set up five specialist agents for characters, creatures, bosses, music and backgrounds, modelled and rigged art in Blender and quantised the renders for the SNES, composed music it couldn't hear and wrote a bot to playtest the game.

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.
