i wish i could tell you. i don't really know anything about crossover. I don't think the response you should be getting is "wait for steam" though.
if i lived were the closest water was 5 miles away and i wanted to get it, but there was going to be a well dug month i wouldn't quit walking for water...
i hope you can get this answered.
and i know that was an exaggeration up there
edit: i'm confused why you need the console mode. it says half life is supported. can't you just press ~ in game?
