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.

The 8th character is a checksum.
