Thank you clamel. The tutorial section has stadium IDs listed. I don't know how accurate or complete the list is. When I tested these courts I made sure they showed up in the correct era. I have not tried any other era. The different eras should have unique courts but that would depend on 2K being accurate. 2K may have used the same file for multiple eras. Most of the time that is not accurate.
As for lagoas courts I'm sure he replaced the correct files. His 1990s courts are for that era only. Since he's the court goat, I trust him to do the correct thing, especially since not all of his courts are free.
I have had issues in past versions of NBA2K when I simply renamed a jersey file and occasionally it did not work. I found the best method to use is to extract the DDS file and replace it in the IFF file. If renaming works then that's good for you.
I used kodrinsky's excellent flickr page for reference.
