GoKawiilHobbyist modifies $45 USB-C hub firmware to pass as Nintendo Switch 2 dock
A hobbyist known as mkopec reverse-engineered the handshake Nintendo's $125 Switch 2 dock uses to authenticate itself, then wrote custom firmware for a $44 Cable Matters USB-C hub to mimic it. After several firmware revisions and a fix for incorrect HDR color tagging, the hub successfully displayed video from the Switch 2, including enabling variable refresh rate support that Nintendo's own dock lacks.
