I would assume the following things:

a) the Chip hase some kind of CPU-Protection (like a SIM-Card or pay-tv card) only giving away its contents after being challenged with the right secret.



b) Dumping the contents bye tapping into an "unlocked" chip after inserting it into the console wouldn't do anything good, because the switch will be looking for the CPU on the flash cart confirming its authenticity. Dumping the CPU-Microcode of those devices is proven to be hard but not impossible.
