Ducati World Racing Challenge Garage Memory Map

Here's a memory map of the garage and related locations in Ducati World Racing Challenge.

Setting the first byte of any of the bike entries will change the name and basic identity of the bike to the one you choose.

Part of the entry obviously corresponds to parts fitted, and another part is the value of the bike, but there are many other bytes the function of which I haven't determined.

Here's the structure of a garage entry (using the first as an example):

As far as I can tell, most of the indicated unknown bytes are not relevant, at least for vintage bikes which can't be modified. (Although if you use a GameShark to set the modification bits on a vintage bike you get noticeably performance improvements.) But I bought (legitimately) two different 60's 500GP bikes, and the contents of their garage entries were very different.

Another interesting location is:

That seems to be the first byte of the vintage bike lot on any day, and any bike code (from 2002-01-10.html) can be placed there, and purchased and used. The locations are actually entire garage entries, so you can modify the price, or fit parts to modifiable bikes.

Disclaimer: Do not use any of this information unless you know what you are doing and understand and are willing to take the risks involved. Even if you do understand the risks, double-check my numbers if possible. (E.g. always inspect the value of a location for consistency before changing it).
