This time SE did a great post for pc, but they always forget something important... The option to play a FF with japanese voices and the texts with any language!

So I will help you for this in only 3 steps.


Open the launcher of the game and put the language text you want, then close it and go to the second step.

Use a modded .exe file that change the voices from english to japanese:
Modded file: https://mega.nz/#!tZgQ1I4I!e3rCYxyP3xtKJLXBQbpud3ll8L0ztwXPnv4YwVgvvSw

Make a copy of your FFX.exe and FFX-2.exe. Extract the rar/zip file inside and play from there or the steam launcher!

You can use this with or without steam. You can not get vac ban for this. 100%

Extra info:
The .exe file just changes strings from this file to change english voice to japanese.
The file has the same name and size.
The file has not viruses (Powered by virustotal):
