I'm new to modding NBA 2K but I'm a computer programmer so I like to think I'm not terrible at computers/modding games. I downloaded this file: NBA 2K20 External File Plugin (Waigua) and extracted it to my NBA 2k20 folder. I then downloaded this file 2K14 Blacktop for NBA 2K20 and extracted s616.iff to the waigua folder that resides in the NBA 2k20 folder. I Then loaded up 2k20 as normal, went to blacktop mode, loaded up a 1 on 1 and my blacktop court still looked blue like the default court:

Does anyone have any ideas of things I can check to find out what I might be doing wrong?
Thanks.
