One of the newer Game Boy Pokémon games is Pokémon Pinball... where you must play the traditional game Pinball in order to catch 'em all! But Pokémon Pinball is far from traditional. There are two game boards, red and blue, on which you can catch different Pokémon and both have their own difficulties. Overall, this is definately more of an arcade game than an RPG. There is also a way to catch Mew in Pokémon Pinball... without a Game Shark or Nintendo's Promo Mew Machine! Mew's Secret will be revealed soon....
More on Pokémon Pinball and screenshots coming soon only to Pokémon to the Nth Degree!!
Here's a screenshot if you don't have the game yet...
