MySims: Made for the PC Cheats

Modify Savegame
First, play the game and grab HAPPY essence (because it is easy to obtain) or APPLE (because it is the first essence), then save. Go to My Documents folder -> Electronic Arts -> Mysims -> SaveData1 (can be 1,2,3 according the savegame number). Open playerRecord.xml with a text editor such as Notepad.

Find the line:

<happy type="number"> (or <applefruit type="number"> )

In this line you can edit the number of essense (up to 99) for example:

<happy type="number">99</happy>
<applefruit type="number">99</applefruit>
