Numpad 1 cheat works fine for me.
However, the Numpad 2 cheat gives me the credits after I finish 1 race, but doesn't unlock all cars nor any levels (the description said that it was supposed to do this.)
Also, Numpad 6 says On, but doesn't end the race. Numpad 5 doesn't do anything either (but does say On when I turn it on).
Numpad 7 unlocks all the episodes of the Season, but whenever I try to do a race in either Season mode or the 1P freeplay mode (forgot it's name), the game completely crashes. This only happens if I turn numpad 7 cheat on.
I downloaded the trainer on 5/29. Any help with these problems would be greatly appreciated. I just want to be able to play all levels with unlimited Power Play. Unlocking all the cars isn't a top priority for me, just the levels.
Also, when I tried using the savegame posted, it crashes the game after the start menu. Did anyone get it to work? I will only use it for 1P offline freeplay races, but I can't get it to work.
I don't know about 5..never really used it...but know that 6 is not working for me...I hit it..but the race continues and I get whatever position I am at in the end of the race..
