HALF LIFE 2 question (not a crack request)

[FarCry]

so i have news!!!! first of all it worked. i replaced the cab files of all source games and worked fine. so now i put in a folder the half life 2 deathmatch its too trouble to put it into the hl2.msi and pu it in a cab in order to install it like the other source games. now the only thing that remains is to make a new msi package with the new steam files and use the databases from the old steam.msi. any ides how can i do it?
