All the cheat codes for The Sims 2 on PSP!!

Hello,
I believe there is only one:

1/ You need to press "select" during the game
2/ Go to "My sim" (L button)
3/ Go to "buy bonus"
4/ Press the "L+R+square" buttons simultaneously
5/ A new bonus appears with a heart icon (it's free)
6/ Return to the game and press "O" to use
7/ Press activate and to the right you will find different functions to click on marked as:

Increase reason
Reset emergencies
Earn $1000
Increase Fitness
Increase Charisma
Increase Logic
Increase Creativity
Increase Cooking
Increase Mechanics

(the more you press X, the more the number (of money or points) increases. This way, you don’t have to redo all this every time you press it). Simpler: for example, if you press "Earn $1000" 5 times
You earn $5000 at once, same for the points...

And that's it.
