I'm trying to get the game to successfully load saves (I'm seeing the same issue that a number of other people here are seeing, but that I've not seen a solution for yet), and when I launched this copy of the game for the first time I got an error that I managed to translate to "Unable to create subdirectory in temporary directory!"
I suspect it might have to do with the folder, game, and files all having "�" in their names instead of actual japanese characters. Would it be possible for you to upload a copy of this where the folder/filenames are unicode encoded so I can try and rule that out as the issue?
