If it's about cracking the product, no, it shouldn't require the
system hardware (though I freely admit that I'm no expert here
either). Also, read below for more...

Assuming there IS a back door, of course. For the 7800, luckily,
there is. But I'd stil love to hear that someone cracked the real
deal anyway...

Except isn't he using hardware to blow out the encryption check in
some way?

It's also a much smaller space than the potential multiplicands of
the big number, right?
Anyhow, is the key even bigger on the Jaguar, the same, or smaller?
I guess one could take a similar approach to encrypting 7800 games.
