Fate Stay Night 2004 PC Japanese Voice+Script Patch

[Gamefreezer]

Hello sorry for posting here wasn't sure where a more appropriate place to ask my question. Recently I cleaned up an old windows xp computer and felt very nostalgic and installed some old games including the old 2004 version of Fate stay Night. I'm reading the game in Japanese I finished the first two routes in Japanese on the ultimate version but for the original the voice and english patch are merged together so when I removed the english patch it also removed the voices. I found the japanese version of realta nua iso for ps2 and was thinking of copying the voice files over but I did not see anything similar to a voice file nor do I know how to convert them into the xp3 file format that patches use. If someone knows where the japanese only voice patch is or a tutorial how to copy the voice files from the realta version I would appreciate it thanks.

Update: After looking around I found some other threads talking about unpacking and repacking the xp3 patch files using tools like kikiriki and KrkrzExtract here are the links to my sources

So far I have tried 3 different versions of these programs and have gotten no luck getting them to work.

The first one I used was the latest build 5.0.0.2 from this link https://github.com/xmoeproject/KrkrE...eleases?page=1
The second one was kikiriki link https://web.archive.org/web/20140714...d/Kikiriki.rar
And the third one was an older 4.0.1.5 build of KrkrExtract based on this tutorial I found on youtube https://www.youtube.com/watch?v=x_V41PoexuM&t=33s

Any help regarding this would be highly appreciated thank you.
