PokeLDN

PokeLDN connects a computer to retail Pokémon games over the Switch's local wireless protocol. My ESP32 firmware handles the radio over USB, bringing the desktop app to macOS, Windows and Linux. Nothing is installed on the Switch or Switch 2.

I designed and built the full app, including its UI and UX, the ESP32 firmware and the game protocol implementations. The interface flashes the board, builds legal Pokémon, queues trades and shows incoming Pokémon live.

Trading works across seven game families, from FireRed and LeafGreen to Legends Z-A, with Mystery Gift and link battles in supported games.
