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.
Detailed instructions for both users and modders offered in the Readme file (latest one included with all downloads). Make sure you read it in full before asking questions that are already answered in it.
Additional Features
As part of its core functionality, this tool forces the game to update itself. Which means that you can be sure you'll always get the latest roster, etc. So this tool also makes my previous tool, "Refresh Official PC Rosters", obsolete.
Newbie's warning
Don't be scared by the number of buttons and features the tool offers. Normally you won't need to do anything other than start the tool and click on "Start Game". The tool is fully-automatic in what it needs to do, that is, force the roster refresh, watch for new updates, and replace any conflicting ones with mods. You won't need to press any of the other buttons to do any of that. Just start the tool, and start the game. The rest of the buttons are either for modders or people who want to use a specific feature manually.
Just make sure you keep the tool running while you're playing the game.
Quick note though, to avoid having the game resync its updates when you quit a game and return to the Main Menu (which takes about 10-15 minutes during which you don't have the Online Data updates, such as the new shoes), remember this:
- When you're about to enter a game, Alt-Tab into the tool and click on Force Keep My Mods.
- When you're about to quit a game and return to the Main Menu, Alt-Tab into the tool, and click on Restore Online Data Backup.
If you remember to do these two things, you'll always have both your mods and the rest of 2K's updates, without having to wait through the lengthy update.

DISCLAIMER
The tool is still in beta, so use it at your own risk. Make sure to keep a full backup of your NBA 2K12 folder inside %appdata%\2K Sports, in case something goes wrong.
When you edit the Roster.ROS file, ALWAYS save the edited Roster in a file WITH A DIFFERENT NAME! The Roster.ROS gets updated by 2K whenever there's an official update, and this tool FORCES the update.
So, two tips:
1. Always keep a backup of %appdata%\2K Sports\NBA 2K12. Always, always, ALWAYS.
2. When you want to edit the official Roster, always create a copy of it first with a different name, and always save to that file. Saving to the Roster.ROS file is unreliable even without my tool, but you're guaranteed to lose your changes with it, if you don't save to another file!

Download
Latest version
- NLSC: Keep My Mod
Version History
- v0.3 - Mar 3
- The tool now edits the downloads.mnf file in the Online Data folder, so that the game's fooled into thinking your mods are part of 2K's update; that way you can keep both your mods and the rest of 2K's updates, something that wasn't previously possible
- v0.2 - Jan 9
- Now Online Data Browser shows all files in modlists but not yet updated
- Whenever the game completes a re-sync, the log should show if new files have been updated by 2K, or if an already existing update has been updated again; in that case the program uses the Windows "Beep" sound to inform the user
- Fixed various scenarios that would cause the tool to crash
- Now Online Data Browser shows all files in modlists but not yet updated
- v0.1.6 - Jan 5
- Tool will now ignore any files that are in modlists but have not yet been updated by 2K, thus accelerating the program's use when a lot of files have been added in modlists, and minimizing copy operations
- v0.1.5.5 - Jan 2
- Tool will now start even if the game's running, but won't hide the rosters, thus avoiding causing any problems to the game; note that this is still an experimental feature
- Manual features "Restore Online Data Backup" and "Force Keep My Mods" will now work at all times; previously the tool would crash as it wouldn't handle some scenarios
- "Restore Online Data Backup" now temporarily disables the tool's automatic features, namely watching for re-syncs and forcing your mods again
- "Force Keep My Mods" now re-enables the tool's automatic features if they were disabled by "Restore Online Data Backup"
- Added a small "Re-syncing..." prompt below the Online Data Browser button that informs users that a re-sync is taking place; this can be used along with "Restore Online Data Backup" to let the user know when they can access NBA Today, Online, and the rest of the features that can't be used during a re-sync; see notes 6 and 6.1 for more information
- The tool now reports whether its automatic capabilities are enabled or disabled, right above the log
- v0.1.4.12 beta - Dec 30
- Tool now checks for the game's constants re-syncs of Online Data and overwrites 2K's conflicting updates with the user's mods after every re-sync
- Tool will try to keep mods even during the re-sync
- Tool is now compatible with both Steam and non-Steam versions of the game; previously wasn't compatible with non-Steam versions, crashing on start-up
- Added checks so that no more than one instance of the tool will run at the same time
- Added check so that the tool can't be started if the game's already running
- Tool now checks for the game's constants re-syncs of Online Data and overwrites 2K's conflicting updates with the user's mods after every re-sync
- v0.1.3 beta - Dec 27
- Tool now keeps backup of Online Data when replacing 2K's updates with mods
- Added option to restore backup of Online Data, in order to avoid having to wait while the game re-syncs the whole Online Data folder; that's because whenever the game can't verify a download in the Online Data folder (e.g. if it's been corrupted or replaced with a mod), it will freak out, delete the whole Online Data folder and download everything from scratch, instead of re-downloading only the offending file
- The Online Data backup, if available, is automatically restored when the tool starts for the reasons explained above
- Improved error checking around the application; should now avoid some crashes
- Improved error logging; crash logs now contain much more useful information for me to try to find the bug that's causing them
- Fixed other minor bugs
- v0.1.2 beta - Dec 27
- Added "Create Modlist" option, which allows you to select your mod's files and let the tool create and load the modlist for you.
- Fixed UI elements' positioning in Online Data Browser
- Fixed bug that made the program parse the whitelist (AllowUpdates.modlist) twice
- Fixed Log auto-scrolling downwards even though new entries are inserted at the top
- Added Readme window that displays this file
- Added "Create Modlist" option, which allows you to select your mod's files and let the tool create and load the modlist for you.
- v0.1.1 beta - Dec 27
- Fixed major startup bug
- Improved error checking throughout the application
- Fixed major startup bug
- v0.1 beta - Dec 26
