[vlmirano]

hi i know this may sound so outdated given that there's already NBA 2K12 but how can i export or convert cyberfaces from NBA 2K12 to NBA 2K11? i'm still playing NBA 2K11 because i still have an ongoing association season which is already on its third year. i hope someone could help me. thank you
