@DanyPPC Your version will be Gold+ regardless of being either the Physical or Digital release (you should see GOLD+ on the bottom right of the title screen to denote the version of Wiz).
The P file patch replaces the P file on Disk2 in GameData <dir> you just overwrite the current P file with the new one. All it does is patch 1 frame of animation (actually 2 for left and right) in the Wiz walk cycle anim. Nothing special and only 1 or 2 people have mentioned it in reality. Like all things tho once seen, it can't be unseen LOL
