Yeah I dunno, my system has been set to Japanese locale for a while now but I'm still getting the crashes. The odd bit is that it doesn't happen until I apply the English patch.
If I run it without patching to English, it plays fine, just with a bunch of gibberish for text.
Also, trying to run via Age Patch.exe gives me an error:
"Error [JPGameRun 0.1, Program by Linser]
DetourCreateProcessWithDII failed: 740"
Not sure what that means.
Edit: The error was due to not running as admin, however the game still crashes upon hearing dialogue.
Edit 2: Going to try installing the Japanese Language Pack and see if that changes anything.
Edit 3: Supplemental Japanese Fonts are needed in require to work, after installing those the game runs fine. If you're having issues with it crashing upon startup, try adding those to fix it.
