I found this out while I was going through my computer files trying to get past the last level in turin where you have to follow the red and white cars through a maze of building and get away from many police cars. I never did complete this level but I found a way to skip it and complete the game. I am using a computer with Windows XP so people who don't have xp might find their files in different locations but the jist of the cheat is the same. What I did was went to "C:Program FilesSCiThe Italian Jobcodeexes". There you will see a list of all the stages in the game, which includes every level and all those other mini games you can play. For me, I had to find the next level after the turin stage I was stuck at, so I wanted the first Alps stage. I found out that the stage (called red white & blue) was stage 76, so i double clicked on stg076. This brought me into the game screen where i played the game on that red white & blue stage. I beat the level (though i don't know if I had to to get to that stage in the game) and after i beat the level the game screen went away and left me back in windows. I then ran the game normaly and to my luck found out that the red white and blue stage was available to me in the real game. Although i did have to beat the level again in the actual game to progress, I didn't care because i had done it once before and was able do it again, so i was able to skip the last turin challenge alltogether and go on to win the game. I don't know if this works for other levels but i assume that it would. Have fun with your cheat to get by those tough levels that you've tried forever at.
