Everything is exactly the same from the PSP game, the messages, popup messages, objectives, etc.
In the PSP game there are normally 3 challenge types: Imperial Enforcer, Rogue Assassin, and Rebel Raider.
So far I've only converted the 4 Imperial Enforcer missions. I will convert the other 2 types in time and update this thread when done.
To access this you need two things:
1.3 r129 patch
Custom campaign support
Look for Imperial Enforcer under Add Campaigns in the game's main menu.

Personal note: I think these are too easy (even on the psp console) I have considered reducing the timers in each mission to add some slight difficulty.
