Start a new game and enter Leemur as your leader name to get 1,000,000 gold and public works.
After activating this code and playing, you will find out later that the gold funds run out very quickly if you buy everything. At this point, save your game, then quit the game altogether. Start the game again, and load your current game again. You will notice that your gold funds have been restored to 1,000,000, but your public works funding stays the same.
