GT PSP cheat codes found - all cars and maximum money
GT PSP
I've been having a dig through GT PSP, and it turns out that it too has cheat codes like GT4 does.
At the main menu (with Single Player, Ad Hoc, Car Dealerships, etc.), hold the listed buttons and enter the below codes. If entered correctly, the menu will reload.
Add all cars to the collection, in their first colour: Hold Start + Select + R: Up, Right, Left, Left, Square, Up, Right, Right, Up, Triangle, Right, Up
Set money to 99,000,000 Cr: Hold Start + Select + L: Down, Square, Down, Left, Right, Triangle, Right, Square, Up, Down, Up, Down
They're a bit hard to put in, but they've been confirmed working on both the European and US releases of the game..
