For reasons I've explained in detail in this thread, I've created this tool.
Starting with NBA 2K12, 2K implemented a way to update game art and text (actually, any game file) silently, without the need for a patch, using the Online Data folder. However, the files 2K updates this way override any mods the user has installed, and there's no easy way for the user to make sure his mods override 2K's updates.
This tool tries to solve this problem, by letting the user select which mods to keep, and also gives modders a semi-automatic way of making sure their mods won't get overridden/replaced by 2K's updates. The tool waits for the game to finish downloading updates, and automatically replaces 2K's updated files with the modded files the user/modders have instructed the tool to.
