1) Make sure your game is paused when changing the value
2) There are two values you need to change. For example, you have 15 energy. Dword search value 15. Spend one energy, Dword search 14 and click on "refine", do this until you there is only one value left. Click on it, click on "Go to". MAKE SURE THE GAME IS PAUSED. Change the value to e.g. 100000. Then take the value four rows under it and change it to 100000X8 (first row: edit, second row: do nothing, third row: do nothing, fourth row: do nothing, fifth row: edit). Go back to your game, spend energy and your energy should change to 100000.
