Unfortunately, you cannot update the rosters in MLB 2K12 for the Nintendo DS, as the game does not support online updates or roster downloads. The rosters are fixed at the time of the game's release. However, you can manually edit player names and stats in some modes, but this is limited and does not allow for comprehensive updates. For the latest rosters, you would need to consider newer games in the MLB series.
You go to the Rosters tab and go to Reset Rosters.
To get Brett Favre on a team all you have to do update your rosters for example when you are on wifi it asks you to save your rosters save them it will automatically update your rosters he should be on the free agents list or on the Jets

Once u here the roster change in real mlb, wait about 2 weeks then (with with live on) start the game, then when is says download in progress , that means it is updating the roster. But u have to be logged into your live account before you start the game or it won't work, like I said when it counts in percent to 100 and says download in progress, its updating what is new in MLB like trades and call ups
