By ClonetrooperI haven't really done much testing with this but its pretty self explanatory. I think you just select your file in the application and choose which player you want to change it to. This is a really cool tool because it provides a feature that is not in the game originally.
By KccitystarNOTE: This patch is only for the DVD-ROM version of the game.
With the game installed, follow these steps:

2) Run mlb2k12_patch_v1.2.0.exe and follow any prompted instructions.
3) If you receive an error message, please ensure the game is installed prior to running.
If you've purchased the game on Steam, make sure your Steam client is up to date and Major League Baseball 2K12 is installed in your Steam Library. If you did not receive the patch via automatic download, it should start downloading the next time you attempt to play this title.
