Actually, there are multiple versions of this dump going around. Both have configuration files that have been edited.
One dump allows the third level to appears after completeing only one level and the other dump allow all levels to be selectable from the start.
On a real machine, you must complete both of the original levels to access the third.
So with that said, no one is wrong in this situation so quit arguing about it.
Conor, you're the one who brought up this dump existing and working with TP, so why don't you reupload and share it for the community? Instead of just trying to flex on emuline for some weird internet clout.
