But I don't know why run the executable $ wine KyonyuuFantajii.exe &> log.txt I didn't get any backtrace but a page fault
Did you meet ``Program Error'' dialog? Basically, when a page fault occurs, wine executes winedbg in background. The winedbg shows ``Program Error'' dialog. If you choose [Close] button on it, winedbg dumps backtrace information to your terminal.
I looked back your attachments, and noticed attachment 49752 shows ``couldn't load main module''. This is winedbg's error message. That's so strange. Just to be sure, did you setup and run this application in Japanese locale?
