Emulator crash on game launch

Hello all, after extensive googling, I couldn't find anyone else with this issue, so I decided to create an account and post here. I recently learned that RPCS3 is a thing and wanted to try demon's souls on it, so I got everything set up, and when I launch the game, 12 little windows appear, each "compiling PPU module" and they all freeze at 99%. A few seconds later, the emulator crashes. I've seen that this game is playable, but no matter how much I mess with the CPU config settings, I can't get it to work. Any ideas?

Thank you for your time.
