About a month ago I managed to forget a DMG with a white backlit (well, it is more blue tbh) on a Delta airplane in NYC during an unexpected change of aircraft. The gameboy had an EMS 64MB USB cart - no sticker, dark gray play it loud buttons and a dark gray play it loud screen protection.
If you should by have come across this gameboy by any chance, please let me know. Finder will be rewarded.
Thanks for reading and spreading the word.
