CheatCodes.com has all the official Madden NFL 12 PSP cheats to unlock everything. If you know of any that we don't have, please let us know.
All published and official codes as of Saturday May 18, 2013 for Madden NFL 12 are shown below. We also have this game on PSP, Xbox 360, PlayStation 3, Wii, iPhone, and sometimes tricks from other game systems will also work on PSP.
When picking your team in exibition mode press the random team select like10 times (not exact) and you will unlock the developers and if you pass it don't worry just scrool through teams and you will have them but it does not unlock them so if you want to use them again you have to do this again but its not that hard so good luck.
