game boy advance sp
 my second game system is a game boy advance sp. the sp is a hand held gaming devise that is about 3 inch by 1/2 an inch when it is closed, and 6 inches by 1/4 an inch open. this is an advancement from the older game boy advance that was 4 inches by 1 inch and did not do any kind of flipping at all. the game boy advance sp has better graphics that the original even though they play the exact same video game corteges that them selves are 11/2 inches by 1/4 of an inch. the game boy advance sp is a sweet hand held gaming system, second only to the game boy advance ds and the play station portable, or psp. for a gaming system i would definitely recommend it
