Posted January 21, 200718 yr So basically I wonder if it's possible to export a game such as GMOD10 from it's GCF and use it as a third party application. I extracted all of GMODS components and put em in the source mods folder, but when I clicked on GMOD as a third party application on steam, it said 'You're not subscribed to GMOD.' I assume it has something to do with the GAMEINFO.TXT, any way to bypass this?
