Millenium 2.2 is just Copylock protected as far as I can recall, so there would have been no need for any cracker to touch anything other than the Copylock routine.
...if i'm wrong, my memory is fading badly
Seems my memory is just fine
SPS 537 is the Copylock protected version
SPS 1511 is unprotected
At no point would a cracker need to do anything to the first one other than crack the Copylock.
I'm wondering however, if by virtue if the other versions tried, load a cracktro up first, allocating memory and thus giving Millenium 2.2 problems?
But as Toni said, no-one reported problems with the game back when it was created so.....
