Surely this is relatively easy to trick?
If backup manager is produced, insert delay code after initiation of timing.
Something like that, just seems like a lame way of checking for piracy to me, of course it depends on the sophistication of the checks, multiple checks between files etc.
Lots of DRM checks on the Crysis 3 PC release, clever, inserts annoying bugs like no ammo for rifle and unbeatable boss. I think the best way to fight piracy from a devs point of view is to implement these random ones all throughout the code in diff games to break diff parts of the game. One security system, ie the firmware is just one line of defense, hope not tho obviously!
