Demon's Souls [BLES00932]

[steppa66]

Hey guys, i'm using RPCS3 since 2 weeks, playing Demon's Souls (eu version) but I encountered a heavy glitch in "Stonefangs Tunnels", level 2-1.
When you enter the cave right after the beginning of the level, after 2 rooms inside, half of the walls in the right are invisible.
I can see the enemies in the upper floor and so... But more importantly, my game crashed there and the save was UNREADABLE after that.
I started a new game and when i was in the same room in the cave, i quitted the game and now i can't load it anymore. (the game doesn't quitted normally, it hanged in black screen loading forever)
2 times in the same spot.
I played every other maps at least the first one in every world (1-1, 2-1; 3-1, 4-1, 4-2, 5-1) without encountering any issue apart from random crashes and minor glitches.

My config is:

i7 4790k @4.6ghz
32gb ram 1600mhz
Gtx 780ti
Windows 10 64bit

RPCS3 config:

LLVM + ASMJIT, Auto SPU, Automatic Libraries, Vulkan, Write Color Buffers, Invalidate Cache every frame (tried on/off: off glitchy shadows but less crashes for me)

I tried RPCS3 version:
5526
5520
5505
5479
5549

same error in every build, i cannot load my save (the game DOESN'T say it's corrupted and the emulator doesn't crash, it just hang in loading screen).

Any suggestion?
