To get your pick of bikes in any race, try this. Go to "Mano A Mano", then have both players select their bikes. Return to the Options screen and set the game to "Take Turns". If you did this right, both players should have their chosen bikes.
For a one-player game, perform the same procedure, but when you leave the Options screen, go back to it and set the game to "One Player".
Bonus Bike
At the title screen, press and hold Up + A + C or Left + B + C, then press START. You'll receive a super bike, the "Wild Thing 2000." Alternatively, enter the password "00DA 1V0N."
Easy Money
For a cool $2,620,000, try this. At the beginning of the game, go directly to the pasword screen and change the first four digits of the password already there to E430, but do not change the last four digits. By the way, to get $2800, use these digits for the first four spaces of your password: 034E. But don't change the rest.
Help Police Officer Catch Biker
Get busted so many times till you can't pay the fine then the officer will ask you to catch a biker select "yes".
How to Get More Money
To increase the amount of money you have by tens of thousands of dollars, increase the value in character 1 in increments of 2 and decrease the value in character 2 by the same amount (you must adjust both to allow the checksum value in the 8th character to remain valid).
How to Increase Level
Increase the 5th character by 1 to 4 (to a maximum value of 5) and also increase the 8th character by the same amount. If you get "Password Invalid", try changing the 8th character until it works.
How to Mark Tracks as Qualified
Select the appropriate value for the 7th character then experiment with the 8th character until the password is accepted. For example, to qualify on all tracks but Arizona, the value 10111 is required, which translates to an "N" (see description above). Change the 7th character to "N" then find an 8th character that works.
How to Select a Different Bike
Increase the 6th character in steps of 2 and decrease the 4th character by the same amount. This will also slightly reduce your money, but it allows the checksum value (character 8) to remain valid. To select the undocumented bike named "Wild Thing", you must be on the intro bike, set the 6th character to "V", then increase the 4th character by 2.
If you want a more powerful hit, hold the C button and up, then wait till you get close to a rasher and let go.
The Structure
Each of the eight password characters is a 5-bit value represented by the characters "0" (00000) through "V" (11111).
The first four characters of the password how much money you have in units of $10. Only the high-order 4 bits of each of these characters are used; the use of the low-order bit is unknown, but it contributes to the checksum in the 8th character.
The 5th character indicates the current level (1-5) in the low order three bits.
The 6th character indicates one of the 16 available bikes in the high-order 4 bits as a value from 0 (intro bike) to 15 (binary 1111, "Wild Thing," available only through a special startup sequence or via the password).
The 7th character indicates the tracks on which you have qualified in the order (high bit to low bit) Vermont, Arizona, Tennessee, Hawaii and Alaska.
