Jerseys are in the zip file, called nsawy.fsh and nshom.fsh
I don't know how your roster is "built", so I really can't tell the best way to install it. You can 
get the roster from DP Apollo and then install the jersey, it should work.
Here is another method, if you only want NC State:
*Create a new team, using the "dream team" feature in the game. Make sure you select the "scorpion" logo.
*Leave the game and unzip the patch in your live 2000 main folder. Then rename nsawy.fsh 

 y1awy.fsh and nshom.fsh 

 y1hom.fsh
*Edit North Carolina State.bat with notepad (right click on the file 

 modify) and change the nsawy.fsh and nshom.fsh at the end of 2 lines to y1awy.fsh and y1hom.fsh. Save and launch the bat file: it's done 
 
Then if you managed to do it, I'll tell you how to update the menu arts to NC State colors (it's the same process as jerseys)
