When this game gets to a certain point, the main character (Haru)'s sprite is missing, and it is impossible to move. However, it is still possible to use items and access menus, etc, so it hasn't locked up. His sprite disappears RIGHT after a conversation with a girl. Anyone else have this game and have the same problem? By the way, I'm using:

Pete's OpenGL plugin 1.58
Null2's Audio Driver 1.4
ePSXe CDR WinNT/2k Core 1.5.0

My operating system is Windows 2000 professional and specs are:
Pentium III 1 GHz
256 MB SD ram
NVidia GeForce 2 MX 200
Sound Blaster Live! Value

Please reply ASAP! Thanks
