Hey guys, just want to pitch in with some info based on running this game on my machine. 


For me there is a pretty consistent access violation error (Exception thrown at 0x00000000121DDF80 in rpcs3.exe: 0xC0000005: Access violation reading location 0x0000000100000000.) that happens during scene transition. So when going to the world map, going into doors/up stairs, more rarely in the menu and on synthesis. It seems to happen less often when not using the LLVM Recompiler PPU Decoder, but there's a part in the game where it starts happening pretty reliably even when using the Interpreter. I also may have noticed this being harder to reproduce with a lower FPS cap and same settings, but I don't know for sure as I wasn't able to get reliable difference stats for this case.


Spec: 
OS: Windows10x64
CPU: Intel i5-6500
GPU: Nvidia GTX 1060 6GB
RAM: 16GB

RPCS3 Settings:
PPU: LLVM Recompiler
SPU: ASMJIT Recompiler
Firmware: liblv2.sprx only
Renderer: Vulkan

The instruction is "[017b6400] 2f 83 00 00: cmpwi  -> cr7,r3,0, #0". It's always that address and that instruction that causes the access violation regardless of how far in the game I am

Strangely enough even though the full error says: Access violation reading location 0x0000000100000000
the RPCS3 log just says: F {PPU[0x1000000] Thread (main_thread) [0x017b6400]} MEM: Access violation reading location 0x0

Also not sure if it's related but sometimes if I transition between too many scenes too fast the game soft locks on the loading screen with music playing, and doesn't stop loading no matter how long I wait

Here is a debug dump from the RPCS3 console at the point of failure:
