I think if getting the SDK was enough to crack the copy protection, it would’ve happened eventually.
The key seemed to be the descrambler.
Why on earth did they scramble the executable in a deterministic way?

(I would _suspect_ that internally, they deliberately made this choice, so that the same inputs would produce the same output, because someone important thought that was valuable and either didn't know or thought it wasn't risky enough to possibly leak key information by doing this. But I have no special knowledge, just a suspicion that people who pick elliptic curve crypto would be aware of the leaks involved in reusing IVs.)
Because they wanted official developers to be able to create MIL-CDs that would load.
They just didn't want anyone else being able to do that.
