Are the extension slots for gameboy color and advanced the same? Could I use a nyoko worm light for a gameboy advance on a color one?

I've replaced shells on the phat ds and it was fairly easy. This doesn't look nearly as complicated. It should be quick and easy.
The only thing I would say is be sure that you are careful with the cables. Make sure you lock them in right. Also, sometimes with new cases if you are having problems getting the metal thing back into the hinges, it is helpful to get a small flathead screwdriver and carve off some of the plastic inside the hinge opening (be very careful). Sometimes there is excess plastic that makes the hole too small for the hinge to fit through and this ensures that you don't scratch up the outside of the case while trying to get the hinge back in.

Well, wasn't the best idea to take it apart. You need to go to the place you bought it from, tell them the problem , or contact Nintendo and see how your Manufacturer's Warranty works, and if its still under coverage. Good Luck!
