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...
I would like to know how to download games from gametdb. Specifically Super Mario Galaxy, Super Mario Galaxy 2, Medal of Honor: Frontline, Metroid Prime, Mario Super Sluggers. If anyone knows how please help me, as it is very annoying.
