(GT2 Version 1.0) GameShark Info about the Multi-Race Series Information
|
At a GT2 GameShark (i.e. mostly hybrids) message board I found codes
which allowed one to generate series in the Code Generator which take
place on arbitrary tracks. Those codes also allow you to pick
arbitrary cars (from the restricted list of about 200 cars available
for the Code Generator).
|
|
This inspired me to inspect memory at the start of the Grand Turismo
World Series for evidence of similar in-memory lists of tracks.
|
|
And, indeed I found them, and was able to exploit them.

As far as I can tell, the first byte above is the event code or number.
I have a vague feeling I have seen it tabulated somewhere.
|
|
As an experiment, I replaced the 5 tracks codes with different tracks,
and the numbers ("5") which follow them with different numbers. (I
used "2"). Indeed, when I did this I got to race against a GTW field
in a series of two-lap races on the different tracks.
|
|
A caveat was that I needed to patch the track code in the normal locations,
too. The above areas of memory actually follows not long after the
race information which includes the starting-lineup. Creating a
GameShark code to change that location only
the first time might be tricky, although quite likely one could arrange
to get the list of tracks set before the first one is copied to the
other location.
|
|
I recorded the locations for a few non-series events.
(Beware, I haven't double-checked these, or the above yet...)
