sadly, the file you linked gives me the same error, the game actually works correctly until i reach the third city (after beating the slime in the dungeon and getting that red gem). but when i try to enter the third city, is crashes saying it cannot find an audio file..and a bunch of files are named with stuff that doesnt even seem right to me, and i dont even speak japanese.
my computer is already set to japanese locale but this file here is the first to give me all this trouble...like if the audiofile was simply...wrong.
