Cheats for sims 2 pets on the psp?

FIRST YOU NEED A LITTLE HOUSE THEN GO OUTSIDE AND ENTER THIS:

CHEAT GNOME: L L R X X UP

after you enter the cheat gnome enter this code:

ADVANCE 6 HOURS:UP LEFT DOWN RIGHT

PET POINTS:TRIANGLE CIRCLE X SQUARE L R

SIMOLEONS(the sims money is called simoleon):TRIANGLE UP LEFT DOWN RIGHT

if the cheat won't work go to town square go to the opposite direction of the arrow and you will see a street light beside that near the restroom then enter the cheat gnome.bye!!!!!!!!
