> What are the chances that I could find the exact charger needed for a GameBoy Colour?
Your chance is 100% because the charger for GBC is 2 AA batteries ;)
Yeah, or you can just get a cheap retro handheld with similar stylings that will charge via -- you guessed it -- USB-C.
Yeah, the GBA SP would have been a much better example. What an odd connector. I really need to get around to modding a USB-C port on to mine.
