Game Boy Advance SP with improved screen (AGS-101).  There are light cosmetic scratches on the body of the device and a few very minor cosmetic scratches on the screen.  All of the buttons work perfectly and have excellent feedback. There is a line of dead pixels on the screen (see pictures).

Everything in the pictures is included:

-GBA SP system

-Super Mario World: Super Mario Advance 2

-Yoshi's Island: Super Mario Advance 3

-Mario Tennis: Power Tour

THIS DOES NOT COME WITH A CHARGER.  However, it uses the same charger as the Nintendo DS.
