Pokemon - Silver Version (USA, Europe) ROM

This is an awesome game! And definitely one of the better pokemon versions out there.
I came from playing the yellow version and I could not get over the difference. The gameplay is similar enough, but the graphics are far improved, not to mention this game is in the johto region, unlike pokemon yellow, blue or red. 
Like all of the pokemon games, you play as a trainer and your object is to train pokemon and collect badges. This game is great fun, even for those that aren't pokemon fans. It's sort of like an RPG, but not.

Enter a whole new world, with new Pokémon to capture, train and battle! Meet Professor Elm and get the all-new Poké Gear, including map, radio, cell phone and clock. Set the clock then watch as day turns to night and events take place in real time-and be sure to keep an eye out for Pokémon that come out only at night!
