Well that might be the case except that the OS9Boot file on the original game 
disk does not contain a separate driver/descriptor for the Pak. All the code 
that talks to the Pak is contained within IBI in the game CMDS directory.

I can tell you that at least one other game, Cave Walker, does not run correctly under NitrOS9 level 2 but runs under OS9 Level 2 fine. I have not tested Cave Walker with NitrOS9 level 1 yet, so I don't really know how much or if this is related.
