I hear too many people complain that they lose the hidden characters on the 360 version of UMK3. Sometimes just going to the arcade mode and getting to the character select screen is enough, but if that doesn't work for you(like it didn't for me) I have a simple solution. After you have put in the codes and shut down the game, the next time you start the game(not the console) sign out of your profile and sign back in. Then go to the arcade mode and to the character select screen. This has been working for me for awhile now ,and its the only way I know to keep them if you're having trouble. It seems like kind of a pain but its easier than putting in the codes every time. I hope this helps some people.
