CheatCodes.com has all the official Need for Speed: ProStreet PSP cheats to unlock everything. If you know of any that we don't have, please let us know.
All published and official codes as of Sunday May 19, 2013 for Need for Speed: ProStreet are shown below. We also have this game on PlayStation 2, Nintendo DS, PSP, Xbox 360, PlayStation 3, Wii, and sometimes tricks from other game systems will also work on PSP.
If you are having trouble getting enough money to upgrade or buying all the cars here's the deal. If you have beaten 100% of the game you would receive all the Race Version Cars. (NOTE: Don't buy the cars, when you beat the game you would receive them as prizes and you would save a lot of money.) If you have the Audi RS4 upgrade it and go to "Mondello Park" and look for the race that gives you the $14000. Enter the race and stay in last place if you like. It is a speed trap race, just stay behind and use NOS when you get closer to the check point. The car doesn't take any damage depending on how you drive but I tested crashing into the wall at 139MPH on the last turn and nothing happened. If you are a good driver go in first and use NOS to keep ahead. Be sure to stay on the road. Last tip: If timer comes up if you are in last place use the remaining NOS if you have any to cut through the field to end the race. You should get $14500. It is better than nothing.
