These files are only necessary for the server! The client doesn't need any files at all.
gamex86.dll - Set teamplay to 1. You can set the hero's weapon at any time in the console with "heroweapon x" where x is mp5, m4, m3, knife, dual, sniper, or hc.
jungle1.hro - This is a sample scene file. When you first load a map, it will look for a file with the name of the map with hro extension. So jungle1 would look for jungle1.hro, etc. In that file, you can set the team names, skins, and the hero's weapon.
Any questions, feel free to contact me.
