I recommend that all players install this program with thier renegade
Renguard:

This is an anti-cheat program that will prevent some of the third party program cheats from working in game. Some servers use options that will check for it and can often throw a popup in your face telling you to get it.
Also, some options involving ! and a command may not work without it.
It is compatiable with First Decade, just change the directory from Renegade (the default for hte installation), to the Renegade stored in your First Decade directory.
When you install it, it will run a window for Renguard 1.03 whenever you start Renegade instead of going to the game. Simply click on the Renegade button to start Renegade.
If you don't want this feature, it will add a Game2.exe to your Renegade directory, which is basically your game without the Renguard feature.
