But of course.
Growing up, I played the shit out of my GameBoy pocket and later the Advance. I still have a lot of my games though not all of them. I remember we had a moving sale once and this chinese guy ended up walking away with like 10 of my games and my gameboy for like 15 bucks. I swear he used jedi mind tricks or some shit, because I don't remember his bargaining to be very convincing...
Whatever though. I had so many good times playing Metroid, Mario, Zelda, and Kirby on that thing. And all my friends had gameboys too so we used to link up and play 4-player which was actually really fun
