I have a black DS Lite that is What I guess would call modded. It has the A, B, Start, Select, L, R, and battery cover from a white DS Lite onto a Black one. I have all of the buttons but the A in black. Will they accept this as a trade in or will I have to find the missing black A button? And as a side question what are their policy's on cracked hinges? P.S. I'm trading it in for a DSi so don't think I know about crappy trade in values.
