Another similarly-difficult NBA exploit, including the US version using a different checksum from the other versions for whatever reason.
The repo can be found here, and the gci files can be found here.

Re: NBA Courtside 2002 Save Exploit
I've looked into this game several times, but even replacing basically all of the bytes in the gci with 0x33 or whatever doesn't really cause any problems, so I don't think that game has an exploit, unless it's pretty convoluted and requires a lot of reverse engineering to figure out.
