Unnamed project
A hobby electronics project enabling cloud save synchronization between a real Super Nintendo console and emulators. The builder wired the SNES's spare controller port to a microcontroller acting as a WiFi bridge, and uses a flash cart whose reset vector is patched to a small save sync routine that talks to the microcontroller.

From the discussion
AI-assisted build process: the author used Claude to read from a logic analyser and iteratively flash firmware tweaks while doing the soldering themselves.
“It was especially magical having Claude read from a logic analyser and flash firmware tweaks iteratively. I still got to wield the soldering iron at least.”

Technical approach: the SNES's spare controller port is wired to a microcontroller serving as a WiFi bridge, and a flash cart's reset vector is patched to a save sync routine that communicates with it.
“I spent the weekend wiring the spare controller port to a microcontroller to act as WiFi bridge. I have a flash cart, so I patch the reset vector to a small save sync routine that talks to the microcontroller.”
