I have my old teal Gameboy color still, I haven't changed the batteries since 2001 and it still works.
I still have my Gameboy advanced and all my games but I don't need the gameboy that much anymore since I have a DS now as well.
decided to dig mine out. not sure where those weird political stickers came from but I think the rest are from those tech-deck skateboards back in '99.plugged some games in, too, but they were all terrible.
the ones I found were Metroid, Cruisin' Exotica and my Gameboy Camera.
