Unpack the "NBA hook" from the start post and put it in your NBA 2k20 folder.
Then go to NLSC and download the external file plugin:

Unpack it and put it in your NBA 2k20 folder.
You see now a folder called "waigua" in you NBA 2k20 folder. Download the "Modded Pack" from the start post, unpack it and put its content in this "waigua" folder. (i don't exactly remember if the content of the "modded pack" maybe already is inside a waigua folder. If yes, just copy this to the NBA 2k20 folder).
