Hi, so, that's a bug that occurs in Castlevania Curse of Darkness in Dragon Boss area, when you try to enter the Boss area the PCSX2 just crash, i think it's an emulation problem, please if you can reply me i'm going to be very plesead, thanks.
Please post the contents of the emulog.txt file after the problem occurs. The file can be found in "My Documents\PCSX2\logs" for the installer version or in "PCSX2\logs" for the portable/binary version.
Please make sure to enclose your emulog in code tags like so (remove the empty space on the closing code tag!):
