You  Can  use  this Cheat for all Campaigns and Scenarios. In the
1st  Campaign  save the game before doing anything else. Exit the game
completly.  Using  a  Hex  Editor (like Ultra Edit-32) open your saved
game  and  scroll  down  to  file  00002e70h. It should look like this
beside it : 00 00 00 00 00 00 00 00 0D 00 08 02 DE 00 00 00.

     The #'s 08 02 equal 520 prestige points. Change 08 02 to FA 99 to
get  39418 prestige points. You can change it to more or less prestige
points but I use FA 99 for a start.
