The first time I did this it made my game very unstable but I did it again and it works stable, but when i try to turn it off it messes up my controlls and then makes it so I cannot reset them in the options menu, so now its on devmode/testmode 24/7
Did you edit the file in wordpad? Or Notepad.
Cause sometimes restoring the file from the disc can fix it.
I have none but if i edit the settings near the bottom they cause instability but turning on just the cheat mode works fine.
Also if you cannot edit the file make sure read only is disabled.
Right-click on file then select properties then at the bottom make sure the box is white for read only.
