Question about Gameshark!

[phil]

I just bought a new Gameshark it's version 3.4 i believe, but this is my question. My Gameshark doesnt plug into the back of my machine, it plugs into a memory card slot and it also came with a cd. Can I run burnt games with this or do I need one that plugs into the back of my machine? Also can someone tell me where I can upgrade the firmware for my cd-recorder. I have a smart and friendly 4424a. Any help/advice is appreciated. Thanks.
