You're lucky that I'm here. Go on ebay and order a tri-wing screwdriver , take the back off of the DS.... look for 2 connections that say F1 & F2 ... bust out a soldering iron and 2 small pieces of wire cut to the proper length... jury rig a bridge across the 2 connections on F1 , and also do the same for 2.
I'd say you blew the 2 fuses :).
