How can I remove scratches from the outside of my gameboy advance sp

if your just want everything to be even, you can lightly sand it down until it is smoothe. if its a deep scratch (like you can put your fingernail in it) then you may be out of luck. you can fill it maybe. try somthing like plastic modeling glue. but all in all, sanding it down works. if you buy a new game boy, keep this in mind: that the best it will ever look. : D
