Difference between PS3 and PC IFF files

I am working on a mod for College Hoops 2K8 on PS3 with Reborn Sports Network, and I have some of the IFF files from that game. However, none of the 2K editor tools work with these IFF files and I can't find the common IFF headers when viewing them with a hex editor, which leads me to believe they are formatted differently from the PC IFF and CDF files.

If someone has any of 2K9-2K12 on PC, could you drop 1 or 2 IFF files with their corresponding CDF files (Preferably the IFF with the menu logos) so I can compare them to the PS3 IFF files that I already have?

Here you go, hope this helps! Files are from NBA 2K11 PC: https://www.sendspace.com/file/2c9s85

Thanks so much!

Out of curiosity, did the logoXXX.iff files get extracted from the logos_small/medium/large.iff files, or are those separate?

No problem! They're separate, all loose in the game folder.
