Glucoboy for Gameboy is this the rarest game/accessory for GameBoy Advance ???

Glucoboy seems cool, i like rare games, recently got a gameboy advance, and my grandpa is diabetic. So it would probably be perfect for me (and my grandpa)

 

Thanks a lot for the detailed info about those "lost" games. I wonder how many players actually could enjoy these? I'm still interested to try these from a .bin file as suggested. Would this still be possible? Thanks in advance.

 

Nice one, jamespoo. I love how they designers even themed the keyboard in the style of the Game Boy, having dark gray, maroon, and light grey keys. The Work Boy - like a mini laptop.
