No, this is NOT the "key".
We don't know for sure WHAT it is, but Glenn and I agree that it's most
likely something like this:
What it is would be more like a file that someone encrypted using the real
key which passed the validation test on bootup. This file is very small, and
just so happens that if you tack an unencrypted ROM image onto the end of it
that the validation code never looks at that code because it thinks the file is
much smaller. So, the validation passes, and the validation code tells the
system that the cart is good, and the Jag starts running the cart at the normal
address (the place where you put the ROM image).
Once again, this is NOT the "key". Think of it more like a
"back door".
