You could that OR, get yourself a tactile switch, like a little button that has 2-4 points. Find the right ends, and connect one to the pwsw point on ur ds motherboard, and the other to any of the pins on the broken power switch. I did this already and it worked nicely, you just have to find a place to put it, a good one is either in the top part of the DS, on the other side of the wifi board, there's enough empty space to have it there and keep the ds tight, or above the ABXY buttons. I bought the power switch and it worked, but you need some good soldering skills, by that I mean to remove the powerswitch without ripping the traces out. If you need anymore help on it, PM me ^_^
