For people having freezing issues, I was having freezing issues on a couple games. I tracked it down to a minor bit of play the carts have in the slot. Even though the carts fit tight into the connector the minor amount of play avalable meant I could consistantly get games like SMB2 to lock up by pulling toward myself with my index finger with light pressure. Or if you had the cart in and tilted the unit a bit it would flop around enough to freeze some games. Must make it loose connection with one or more pins I suppose.

I put a couple thin strips of gaffer tape on the inside of the cart slot to tighten it up and I haven't had any problems since. Overall I love the system, I play FF1 everywhere now.
