PS: sorry i cant kill you my mom said i have to come in for dinner. 

If you mean that the scratch is so bad to the point that it is deeply engraved into the DS shell, then there is no way to fix it except replacing the DS plastic casing in its entirety. I know of websites that sell DS enclosures, but it would also mean you'd have to be able to take apart your DS in order to replace the casing. I'm not sure about repair shops, your best bet would be to notify Nintendo, but I wonder what kind of excuse you'd have to come up with for them to replace it...If it is under warranty that is.Brainhunter

it is under warranty i just bought it about April 7 or something like that it was my b-day present (my birth day is on April 11th not 7th by the way) and my friend dropped it two days ago so i might replace the plastic on it but we'll see 

okay it is scratched to the point where it is noticeable from about two feet away and my friend dropped it

PS:im not letting him touch it any more
