Demon's Souls [BLES00932]

Hello, I have a problem with the game when I try to boot this error occurred:
S Successfully installed PS3 firmware version 4.81.
E LDR: Invalid disc directory for the disc game BLES00932
S LDR: Boot Game: boot done.
E PS3 executable not found in selected folder (D:/Emulator/PS3/dev_hdd0/game)
