there are several options:Every time I try to extract files it just fails, anyone know a fix?
1 poor internet connection, the downloaded file is simply damaged
2 you are using WinRAR... an extremely common, but extremely bad program that, with a certain chance, cannot even unpack the archives that it packed 5 minutes ago, I advise you to switch to 7zip
3 problems caused by the locale, if you have Win10, then there should be no problems with unpacking, it perceives hieroglyphs quite well even without switching the locale... except for very specific cases... otherwise you can try changing the locale
for idiots like me: do not run this game in Japanese locale, it will break the game and you will not be able to get the ending... also some indicators in the menu will be broken...
