Here is a little CLEO script for locking a 4, 5 or 6star wanted level in GTA SA.
It is intended for toying around and not for serious gameplay.
Put the .cs file in your CLEO folder.
Press one of the following keys to trigger a wanted level:
F4 - 4 stars
F5 - 5 stars
F6 - 6 stars
At the time of writing, the existing wanted level scripts on gtagarage only set a wanted level once, but do not keep it. I wanted to try out some races on 5 or 6 stars but these wanted levels usually drop by one before the end of the race. So I made this script to actually lock a wanted level to a selected minimum.
The selected wanted level will be a minimum.
Say your max. wanted level is 5 and you use this script to lock 4 stars. Then you could still get a 5th star if you commit crimes. You can reduce this back to 4 by the usual means, but not below 4.
Once triggered, the selected wanted level will remain in place until you reload any save.
This means that you cannot switch between the different levels once the script has been activated, nor can you clear your wanted level.
If necessary, your max. wanted level will increase to match your selection.
Triggering this script will set the cheat flag and increase the "times cheated" stat.
