I didn't say that either, I was just saying it doesn't work for this game cuz you gotta install it without making the japanese characters garbled, which means you need to download it in japanese I think?
Japanese, without this the name encoding will be broken and the game will not run
It's the unicode actually, aka when it's getting extracted, it's extracting it on a american (I'd assume in this case) system. The american system is not able to detect japanese characters properly, hence why it bugs out.
7zip doesn't really have an option to do it, so I recommend you do what I do, use 7 zip for everything else in your home language aka english for me.
Then use bandizip (another rar/zip file extractor/archiver program), on bandizip go to options > settings > extraction > default code page > japanese
Then use bandizip to extract japanese game zip files, that way you don't have to do the other more painful method of having to run the game in japanese locale everytime.
