You will need jump cheat to do this. Anyway, in level 6 jump through either of the waterfalls near the sign that says "SPRINGFEILD" (it's in big white letters). So jump through it and you are in "glitch zooone" (aka the sky) and it is fun! So have a BLAST!

To win races alot esier(excuse my spelling) type in these at the main menu(no that's not during gameplay)enterat the main menu's options:

Four triangls=top speed
Triangle x triangle x=invincable car

Or you could murder the other racers

Triangle triangle square square=one hit wrecks
Crash into the other racers and they will blow up


This is also a good 1 not reely for races though:
3 squares, triangle=pressing analog makes you're car jump!

At the options screen use th cheat fast acceleration (square x4) and the unlimited top speed cheat(Triangle x4) and go to Homers first level. Use Marges Canyonero and go to the bridge leading to the poor section of the area. Face left of the bridge and back up. You must be at the middle of the bridge and facing the water. As fast as you can drive towards the water. If you do this succesfully, you will be under the level*. You can go any where you want. To get back ontop of the level make sure you are exactly under the level and press select.

Part 2: Use the cheats above and go to either lisas or barts second level. Go to the light house and start at the bridge next to the ship facing the light house. On the side of the light house, there is a small ramp like thing that is part of the light house. Drive as fast as you can and hit the side of the light house. If you did this right, you will be under the level*. To get back up press select under the level.
* some times you might be transported back up to the level when you go off the level. This may happen if you don't go fast enough. Just keep trying.
