For those interested in finding a better way to remove those nasty screws, I was able to find a cool site that sells security bits that can be used to remove the screws in GB, GBA, and SNES cartridges. I'm not endorsing this above anything else, but I've tried the 3.8 mm and didn't have any problem loosening the screw used to hold both Crystal and Silver together.

They ship via USPS, and their payment is through Google or Paypal. It took only two days to get the bit, and I've been ecstatic ever since.
