Atelier Ayesha: The Alchemist of Dusk [BLUS31152]

Unfortunately "MEM: Access violation reading location x" is a very generic message that means nothing without a debugger and at least a stack trace... You could try some old builds here: https://rpcs3.net/compatibility?b but performance will be abysmal just a few kd-11 commits back unfortunately. But you can at least see if an older build fixes it. Then we can track down where exactly it broke.

Managed to change party member and finish the game. I don't know if it is any help but this is what I noticed.
The problem is somewhat related to FPS. Using certain techniques in battles, going to certain areas causes a permanent drop in FPS. FPS will go lower and do not recover to original unless I load from a save file.
On World Map, I have close to 60FPS. When I entered certain dungeon and exit, the FPS became 40+ on world map unless I close RPCS3 and load again. Lowest I had was 14, else 25-30 were my framerate in town/dungeons. If my frame rate doesn't go below 20, none of these problems are encountered when loading from a save file.

Just curious what's this error from compiling:
E {PPU[0x1000000] Thread (main_thread)} PPU: [0x00417bac] 0x00417bdc: Error: MTFSF
E {PPU[0x1000000] Thread (main_thread)} PPU: [0x00417be8] 0x00417be8: Error: MFFS

Recruiting Juris was hardest since he's in a town that has abysmal framerate.
To recruit character successfully, I need to go from screens that has better FPS and teleport directly to that of the character. Managed to recruit Wilbell by teleporting to bakery, leaving entrance and talking to her. If I travel from my atelier to her, the game freezes on recruitment screen everytime.
