This isn't an NLSC roster patch issue as such, but I'll take this opportunity to provide an explanation on a couple of points.
The roster updates are not automatically compatible with art updates for missing players, since not everyone that downloads the roster update will also download player updates. Hence, created players still have their created appearance. You will have to do a little DBF editing or modify the folder names the render/xplayer folder to match the created PLAYERPKGs.
Custom art has been explained before, please do a
keyword search of the forum.
