How to open up Famicom carts?

I know it's not neo related, but I was curious as to how I would go about opening up a famicom cartridge? I just picked up a prototype and I would like to check out the boards and chips and see how they differ from standard releases. Thanks in advance.

there is a Screw under one of the stickers

Ah man, that sucks. I'm not willing to remove the label just to open it up. Thanks for the info. It's not like I'm concerned if it's a prototype or not, I know that it's a proto for a fact already. I just wanted to see the boards.......oh well.

what game is it?
