Usually when you start a 2-player race across the US only 1 person gets the upgrade. BUT, when 1 person selects 1 save file and the 2nd person picks another, you can stop that! First pick different save files. Pick different cars next. Finally,race up to Washington DC. Pause and Quit the race then RESET (do not turn off and on!) the machine. Re-enter the game using the files used in the the 2-player game Finish the race with both cars and you will have 2 upgrades! Two tricks.... Chicago-- As you begin the race, you will be on the freeway. After the first two turns, there should be a broken down car. If you hit the car (causing it to FLY through the air) it will land in front of the first place person. It takes practice to hit the car, but once you get it, it will be a BIG help for the tunnel. Golden Gate Park-- You will be able to get ouside of the fist bridge. If you make the turn at the right time, you will fall over the bridge, and land up in a higher position. This one is VERY hard to get the timing right, but it works!!! Its more of a warp that just falling off of the bridge. Shortcut In the Grand Canyon after the first check point stay along the right hand side untill you see a dirt ramp that goes up.When you come up the ramp you will see a land bridge, go across it.{if you go to slow you will fall off}This will somtimes give you a big lead over the other cars. There is another shortcut like this to the right in the beginning of this stage. Bugs and other shit When racing Iowa or Indiana, if you zoom all the way in (so you are looking out the windshield) bugs will occasionally splatter on tour windshield and when birds fly overhead bird poop will splatter on the windshield. Have Fun! Falling coconuts In Beverly Hills, run into any tree on the side of the road and coconuts will fall out of the tree. Not much of a trick, but still pretty cool. Lost Wheels After a two player challenge game, the losing player's Right front wheel will fall off if you continuously rotate the analog joystick clockwise. This should happen after the car rotates 3-4 times. Talk about driving till the wheels fall off!
