Ho Ho Ho, Merry Christmas Everyone!
Please accept this gift from Santa to all of you little boys and girls.
This is iffset, it works a lot like the existing NBA Live program FSHline.
Install the latest C++ Redistributal package (included or download on your own, because of this )
Start by moving your iff file to the same directory as the Start.bat and iffset.exe
Then start the start.bat
In the command prompt type "iffset -x 'name'.iff"
Edit the extracted bmp files as you wish and save as a dds file according to the bmp filename. So if a bmp has DXT1 at the end of it, save it as a DXT1 dds file
Once you are happy with your edited texture go back to the command prompt and enter "iffset -p 'name'.iff texturename_DXT#.dds"
