The secret codes/easter eggs thread got me thinking...
There was a time a ways back when I was playing a lot of Road Rash on the Genesis, and started thinking about the password system... It was easy to see how your placement on the various tracks was saved, and I started trying to figure out the rest of the password too.
I figured out a few things, like what bike you owned (IIRC), your winnings total, and how Natasha reacts to you, but there were other things I never managed to decipher, like your money total (possibly vice versa with winnings total), and there were three bits that appeared to be a checksum.
Has anyone else tried to figure this out? Or for any other games? And if so, were you successful?
(My brother started trying to figure out the passwords in Survival Island on the 2600, and I mostly finished up the work years later; I documented it in the 2600 Connection).
