what is the correct size of screwdriver to disassemble nintendo ds lite

[Tapshyon]

all the phillips head i have are either too small or too big for it, i have the one to unscrew the golden phillips screw but i can't seem to find the right fit for the battery screw.

sorry for my bad grammar.

I've never taken a ds apart, but you may need a special screwdriver thats designed specifically for Nintendo stuff.
