Simpsons: Hit and Run Cheats

When you buy different costumes, in each level the character you select will react differently when you allow him or her to remain idle. For example, choosing Bartman will have Bart jump up and fly around for a few seconds.

When the screen pops up at the beginging hold both triggers and press A A A A X A B B B Y B A X.
Then when thhe cheat menu pops up type in:
Cheesebag: you get to throw bags of cheese
Jolt: makes you move faster

I have a few cheats here that will help you beat the cops, and some that are just kinda' random :D

The 4 codes that let u hav fun wiv hit & run!

Ok first this cheats only works on Alien "Auto" Topsy Part 1 and Second you CAN'T use a bonus car for this cheat to work.

First start the Mission then keep on continue it untill the part when you get the Toxic Waste then grap the toxic waste and quickly cancel the mission. There is a chance your car may Still have the Toxic Waste. (note: DO NOT drive the car with the Toxic Waste in the Tracter Beam because that will deactivate this effect Permanently)

Ok to get the boat car, you have to play the squidport level with Lisa. During one mission u find Bart on a boat. After u talk to him jump up onto the ledge and explore the deck of the boat. Along with finding a collector card, u should also find a boat car across from the collector card.

Now to find the Monorail car, u have to play the downtown level with Marge. During one of the missions, you'll come to a broken monorail track on a small street. go up the stairs to the monorail and jump onto it and jump in the first car. Then u can drive the Monorail car!! There will also be a collector card there too.
