anyone know where to buy a screw driver to open up the gameboy advance sp?

Why would you like to open up a GBA SP? It's not my business but i am just curious.

Try www.Tritonlabs.com. They sold them so people that bought the afterburner light kit could install them in their GBA. I think i got a mini Y-screw and philips for like 6 bucks.

You can simply use a small jeweler's screwdriver. Insert it firmly and it works like a charm.

This has been discussed before and someone mentioned a craftsman product number that will fit. Can someone please post that again.

thanks

I don't know part numbers, but the bit is a standard security bit, you can find it in a lot of hardware stores that stock security bits.
