I have finally found a config file that works online for L4D . This isn't my work credit goes to Nubbin You from Game Tuts. Though it works it can be glitchy. I believe it because of the ent_ used in the command line in the config. I'm sharing here as no one has posted a working one on this site and hoping the usual suspects (Cabbose, BxRKings, ADDZ, Enigma & Ccaveman84) could fine tune it to a XPG quality. Hope this helps anyone else. zip0.360.zip https://www.dropbox....g7/zip0.360.zip Read Me https://www.dropbox....ds%20config.txt Instructions: Replace the zip0.360.zip in the "left4dead" part of the iso. No need for padding as I've already done all of that.
