I have this prbolem with TWO of my Genesis 2 systems. I know the reason. The cart slot. The pins are pushed in so far that the contacts don't touch the pins. The cart slot looks Brand new, in fact.
My 32x's cart slot looks the same and the 32x runs better than these genesis systems!
Is there some way that i can fix this? It's very annoying, since i want to sell a genesis (Model 2) system but can't since it HAS to work like new.. The genesis Model 2 systems that i have that work the best are here to stay.
