Ive seen them done on the download section on the 360 but how could i go about making my own or if someone could create the one id like to use for my career?
the ones you are seeing are taking unused cyberfaces on the disc and applying them to a created player with Leftos' roster editor. you cannot add new custom CFs to the 360 version.
any probably the best/easiest to use PC controller is the 360 controller. If you have a wired one, you just plug it in and you are good. Wireless ones need a wireless receiver, and do not work with the play n charge wire.
