I am playing old ps2 games with my friends on a ps3 and a ps2 in lan. Does anyone know the codes to unlock all the cars and tracks in atv 2 or 3?

In hotwheels stunt track, you can use the name monkfish to unlock everything.

Mtx mototrax, you can enter 2468g0a7 in the code area to unlock everything.

Any codes or links?
