Why do I need either of these? AppLocale and NTLEA may or may not work with certain programs. One may work where the other does not so it doesn't hurt to have both. The foolproof method seems to be changing your non-unicode language to Japanese, but it's a bit of a hassle which these programs can help with. AppLocale This program is only made to run on Windows XP and 2003. Basically what this program does is give applications the ability to run in a different language environment than the one you're running (probably english). A lot of H-Games need this to run on an english installation of Windows XP. To use this you need to have the east asian language files installed. You can check whether or not you do by going to Control Panel -> Regional and Language Options -> Languages tab -> bottom check box. Download the installer here. Code: http://download.microsoft.com/download/5/6/8/568a8caf-29c4-43ec-a10f-97730f26977e/apploc.msi Optionally, use this .reg file attached here to add the option to run AppLocale through a shell extension. There's one .reg file to add it to the context menu and one to remove it. It saves a lot of time. NTLEA v0.87b Code: http://www.mediafire.com/?zzduyyzzwjx Thanks to _matt for telling me about this program, it works quite well. There's no installer and doesn't seem to effect your WIndows files at all so it should work with Vista as well. I've only tested it on XP so far. If anyone knows the homepage of this program please let me know so I can update this post with the info. The link to the programs homepage in the actual program doesn't seem to work. From what I gather, some Japanese games don't run even with AppLocale and the only way to get them to run is to change the non-Unicode language to Japanese, which can be a bit of a hassle sometimes because it affects multiple parts of your system and requires a reboot everytime to change it. NTLEA seems to be able to do the exact same without rebooting or changing this setting off of english. These are the settings I have, this dialog opens up when you open ntlea.exe The "add to shortcut menu" checkbox adds NTLEA as a shell extension when you right click executable files as seen in the right of the screenshot.
