I remember when I was in high school and begged my parents to buy me a TI-85 graphic calculator. No, it wasn’t really because I really needed it for pre-cal, it was for the not even 8-bit games I could upload and program into it.

Super geek Alentris however, does one better. While I was playing black & white Tetris he’s playing old school Gameboy games. How did he do it? He built a Gameboy into this TI-83. It only took about thirteen hours, but the end result is a thing of pure gaming beauty. Not only did it not explode in his face, but it works to perfection. My only question is how does one switch games? ROMs perhaps?
