I've followed the top guide to the letter, and read the whole thread. YOU HAVE TO MAKE IT JAPANESE LOCALED EVERY TIME YOU LAUNCH 7-ZIP! See second post for further instructions. 5) Run 7-Zip with Applocale - right-click on 7zFM.exe, choose 'Locale Japanese'. 4) Install 7-Zip This is critical to success! WinRar won't do, it messes up Japanese chars regardless of locale. 3) Install Japanese RTP with Applocale - if you've installed all the stuff for AppLoc from the step above, you have to just right-click the RTP installer and click 'Locale Japanese'. Well, when you read that page, it's all pretty obvious. There is also a patch and some register keys on the same page, install'em all. 2) Install Applocale - it works both for XP and Win7.

In case you're still here w/out it: But you most probably have it already. There we go: 1) Make sure you have Japanese language installed on your system - what the hell are you doing in /fg/ without that anyway?. Still post here if something doesn't work.

Implying you read it carefully and do stuff consequtively. Finally! The solution to all your Japanese fangames troubles are in this very thread! Links provided.
