Posting this in here too and not just the save data thread seeing as it's relevant.
Here is the most probable results for most the ???? faces. These players at the very least look very similar to the pre-sets
Faceslot 435, hairslot 4510 - Samuel Kuffour - Ex Roma and Ajax player. Was in Pes 2008 and 2009 as a classic player. face and hair of pre-set is very simular to the man
Faceslot 645 - Robbie Brady - Some agree but plenty disagreement on this one too.
Faceslot - 1555, hairslot 5630 - Looks very, very similar to Rayo Vallecano wonder kid Bangoura aka LASS. Has been linked with a move to Real Madrid since 2011. Not just the face but the hair makes me think this is very much meant to be him
Faceslot 1575, hairslot 5650 - Looks a lot like ex-City player (from when they were more of a nothing club) Paulo Wanchope. Again both face and hair is convincing.
Faceslot 1593, Hairlslot 5668 - Jamie Langfield off of Aberdeen - had a pre-set back in 2010 when Aberdeen were in the game and he was one of their key players. This is definitely him.
Faceslot 1803, hairslot 5878 - I have assigned to Craig Bryson in my save. Looks somewhat like him but not as convincing as Langfield, Wanchope, Kuffor and the rest.
Faceslot 1810, Hairslot 5885 is definitely current Rangers player and ex-Scotland international Kevin Kyle. I am convinced this pre-set is either from when Hearts were fully licensed in 2010 or if he was part of the licensed Scottish national team when Konami put him in. It looks very, very like him.
Now for the -=free=- faces which are incomplete pre-set builds by Konami so you need to combine the pre-set face with a different licensed hairstyle. The following combos have given great results on my save....
Bradley Johnson : Face slot 1156 + Hair slot 4452
Marcos Alonso : Face slot 1460 + Hair slot 4605
