I had a look back through my archives, and these were the only versions of my original NBA Live 2005 (2005 season) rosters that I could find. Unfortunately the earliest available version is January 7th so no opening night rosters, but final rosters should be included. Anyway, I've thrown everything I could find in a .7z archive and uploaded it here:
