I have an idea:
An open-source USB-C dongle (RP2040-based) that lets any modern device (phone, Steam Deck, Android handheld) emulate a Game Boy Advance connected via the official GBA–GameCube link cable. Restore Tingle Tuner in Wind Waker, Four Swords Adventures multiplayer, Crystal Chronicles co-op, Chao transfers, and dozens of other features on real GameCube or early Wii hardware — without needing rare original GBA hardware or cables.
I have created a GitHub repository.
