Wow this worked perfectly! I tried doing split screen multiplayer with the x360ce XBOX 360 controller emulator but I couldn't get controller 2 to look up or down. I would tell people that they should execute these 3 commands from the command console in game to get it working though. The first command you already have.

exec SPLITSCREEN_2_XBOX 360_CONFIG.cfg
ss_map <after you type that and press the space bar press up or down to pick a map to load>
connect_splitscreen localhost 2

Now you're all set and ready to go. Thank you again!
