Like most kids who grew up in the 1990's I had a Game Boy. I used to play all sorts of games on it, from Pokemon Red to Pokemon Blue.
The last Game Boy game to be released was Pokemon Yellow in 1999. Nintendo has released a number of handheld systems since then while our Game Boys gather dust. However, recently a current child tried to play Pokemon Yellow on a Game Boy and she confused by it in the most adorable way.
