Follow the steps below for speed hack in cs 1.6:
First download and install Cheat Engine from here.
Start your CS 1.6 / Condition zero/ CS Source.
Run cheat engine.exe file.
Now open the list of running processes by clicking on the first icon in the toolbar.
In the process list search for your game process. Select it and click on open.
After opening the process check the “Enable Speedhack” option. Drag the arrow on the bar to increase the game speed.
Open cmd and navigate to C:\Program Files\Valve\HLServer. To do this type cd C:\Program Files\Valve\HLServer.
Now type HldsUpdateTool.exe -command update -game “cstrike” -dir and hit enter. This will install the server files on your computer.
In this process it downloads the required files from the server(~ 300 mb) so it may take some time depending on your internet connection.
After the files are downloaded you will see a “HLDS installation up to date” message.
Now your server is ready all you have to do is start your server and set the options according to your needs.
To start the server go to C:\Program Files\Valve\HLServer and double click the hlds.exe file.
If you are behind the router you may have to do port forwarding. To know if you are behind the router or not go to cmd and type ipconfig. Now see what is showing in opposite the IP ADDRESS. If it is something like 192.168.1.xxx then it means you are behind the router and you will have to do port forwarding. For more info on port forwarding go to portforward.com.
While roaming around I found this cool hack for noob cs players. It is CS 1.6 aimbot , works just perfectly. I have tested this and it’s safe to use. WORKS WITH CS 1.6 ONLY.
HOW TO USE???
[sociallocker] [/sociallocker]First download and extract files from the link given at the end of this article. Start your cstrike game and connect to any server or start new game on your system. While it is loading press alt+tab and run leis.exe. Then go back to your game. Now you can see the difference. This will work only if you start the bot while game is loading, if you start it during the game then it will crash your game. So use it appropriately.
