That's funny... Been trying to do this since last evening and whenever I do change the sheriff files from patchday3ng, it's just still there, except that theres a white-shade of the original sheriff vehicle and when I turn on the siren on the car-select screen that shade starts spinning on the flashlight's axle :D
Now as funny as that sounds, it has actualy been very frustrating to me :D
It did work for sherrif2 tho, however when I try to replace FBI2 in x64e it also changed nothing.
Regards
