Tales of Xillia [BLES01815]

Hello everyone! I'm new here and i know i'm commenting out of nowhere but i have something to discuss/share some information in regards to the infamous Unregistered PPU function error in Tales of Xillia. And no sadly i haven't figured it out how to fix it but i've been meaning to say a couple of words for some time now so here i am. After weeks of experimentation i've come to realize that this error pops up at the result screen late game ONLY when you have Milla in your active party or if you have more than 3 characters fighting alongside you in battle. For example as we all know the game has sections when your team is separated and you gotta fight either on your own or with at least one or two extra members of your team. One such section in the late game(SPOILERS!) is after the Fezebel Marsh battle when your entire team is spilt up. I am playing through the Milla story so that's when you have to play as Milla alone for some time. And what do you think the game didn't crash after battle not even ONCE! And even when(SPOILERS!) Milla finds Rowen and Leia and they accompany her for some time untill you get your entire team back the game still didn't crash at all. But once i had my entire team back and i tried fighting a random monster again...Well the game started crashing again. For some battles it helped to not have Milla in your active party but sometimes it's just doesn't matter and the game crashes anyway. Especially it likes doing that when you fight bosses -_-. So that's where my idea of having four characters in battle being the reason for error comes from. If you want to know how i managed to get this far into the game i just had to use one of the old versions of rpcs3 which for some reason doesn't have this error. In fact that's how i'm playing through the game right now. When i get Unregistered PPU function error i just swap from the newest build which has the fixed text to the old version just to get past a battle i couldn't get past before. The version i'm using to bypass the error is -> rpcs3-v0.0.4-2017-11-27-695b4c1f
P.S. Appologies for what seems to me is a gigantic amount of texts which probably i should've spilt into small messages.
