That's pretty amazing stuff.
So cool knowing that an emulator was actually stealthily locked away in an inaccessible fashion on such a classic game!
Would have been neat if it were accessible via some computer terminal in the game. We've wound up seeing similar things like that in other/future titles like Maniac Mansion Day of the Tentacle (Maniac Mansion) and Call of Duty Black Ops (Zork).
