on the create a sim screen click on any tab except tab1 then open the cheat box (ctrl shift c) type in boolProp testingCheatsEnabled true. go onto tab 1 and in the name box type the letter N (make sure its a capital). when you move that family into a house you can then slide the motives around! hope it helps <img src="http://i.neoseeker.com/d/icons/smile.gif" border=0 vspace=2 alt="" />
by the way this may work on any version :-)
First type up BoolProp Testingcheatsenabled true
in the cheat box.
Then Be the sim you want to have the handheld game

Then hold down shift and clik on that sim Then clik on more and it should say somthing like "handheld give handheld game" or "give handheld game" clik on that then your sim will hav a ds.
If you want your sim to play on it just clik on him/her and clik "play handheld"
