Ive not seen one yet, im dying for a dark one!
I aways play with the dark skin, i tried that FMC skin, looks ok, but some things didnt seem to fit and some txt was overlaping in places but maybe that was just me?
Put it in-my computer-C-drive-users-(you!!)-my documents-sports interactive-fm2012-
Create a folder called skins-put in there!
Open fm-preferences-choose skin.
