I'll tell you what I did. I had the same problem as you and didn't want to spend the cash. However I must tell you to do this at your own risk and I accept no reponsibility..
What I did was get a small flathead screwdriver, ok this may be hard to explain. Look at the slots on your system, you don't need to remove the casing to do this whole thing, however it takes a good 10-15min. Look at any contact pin you want, notice how at the top of the curve there is a piece of straight metal pointing upward? Every pin looks like this.
Now what I did was, push the flat piece straight back (away from the center of the slot) to the plastic edge of the slot, then with the flat head perpindicular to the piece push down on it.
Essentially what is happening is that you are making the curved edge of the contact pin bend out further. Thus making a tighter connection and tighter space between the slots. You have to do this to all the pins, kinda maddening!
My Phantom works fine now and I did this about 1week ago. You may get a screwy picture so try inserting the cart at different heights and you will eventually find a sweet spot.
AES games work fine as well just a little tight, barely have to push them in to get it to work.
Confused yet???
