2009 maps to 2007

does anyone know how to get source 2009 maps transfered into source 2007 correctly?..
and proper models…?

I was wondering this too actually, aaaaages ago.
An old version of hammer would do even, could compile the map for oldcs :stuck_out_tongue:

what do you mean an older version of hammer?

What part of that phrase could possibly confuse you?!
