Tales of Xillia [BLES01815]

This error:
F {PPU[0x1000000] Thread (main_thread) [0x00879510]} class std::runtime_error thrown: Unregistered PPU function

Is usually fixed by using PPU interpreter (fast)

All tests must be done on master for compatibility reports aka: https://rpcs3.net/compatibility?b

Thx for answering.
With fast interpreter on  RPCS3 v0.0.5-6638-568118634 Alpha | HEAD  I got 

F {PPU[0x1000000] Thread (main_thread) [0x006af464]} MEM: Access violation reading location 0x207e00ec
E {PPU[0x1000000] Thread (main_thread) [0x006af464]} Stat: 'sys_ppu_thread_detach' failed with 0x80010005 : CELL_ESRCH [x5]

I´ll try to test a few settings and more versions. Will report back when I find something.

Edit: Still the same on many versions but I´ll try more.

the F {PPU|0x100000]....etc lines are from the console log, which just throws 'generic' errors.  if you'd like to help, 

every time you EXIT (close) the RPCS3 executable after running into your problem, like the memory access violation your console logged, the executable will create a log file found where the RPCS3.exe is in your folder.  if you play for awhile, it can be quite large, so just try to get to the point it crashes, let it fail, then exit the program.  a log file (usually; hopefully) will be created and also an archived version of the log file will be created.  i.e., "RPCS3.log.gz"  you can drop that archive here in the forums when you reply.

ss std::runtime_error thrown: Unregistered PPU function

Vulkan / Default settings

Game crashes when I finish some random battles.
Now I got at an "obligatory fight" and every time I end it the game crashes so I can't progress into the story.

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.

Still the same on
RPCS3 v0.0.5-6652-41f4bb901 Alpha | HEAD

If you want to bypass the error just use one of the old versions of rpcs3. It doesn't have the fixed text yet but should be enough for you to get past the error. Then switch back to the newest built until the error pops up again.
I use this version ->rpcs3-v0.0.4-2017-11-27-695b4c1f to get past the error.

That´s what I´m doing too. Just want to help to fix it but real life isn´t giving me much time either right now. I try around a bit more.
1 issue I had on a other emulator could only be fixed when I turned off all my virual cores and then the game could continue.
The same on smartphone roms. Trial and error from the best but its fun.
Sorry for the OT.
