Aliens versus Predator does not work with SmartSteam Emulator. The game will launch (It takes about a minute due to the CEG protection not being fully removed from whatever crack I am using.) and you can try to create a "player match" (unranked match), but it errors out with "a connection to the game timed out" error screen in the game.
The SmartSteam Emulator log appears to show no error though. Here is a pasted copy of my log file:
