Need Help! How do I open an Atari 2600 Activision Cart?

[Schiggidyd]

Topic says it all! I may have my hands on an Activision prototype of Spider Fighter, but I can't open it up to see the chip inside! Any hints or guides would be appreciated!

Send me a pic of the cart and I should be able to tell you.

There are two screws under the label.
