Voice Patches for Zero & Ao no Kiseki [JP]

[baten]

I'm no programmer, so this whole tutorial goes a bit over my head. Actually with only 2 steps i don't understand at all what to do:

"5. Add script files(.bin) with voice instructions to ISO via tools/AddScnsToIso"

I visited this github page (https:// github.com/ZhenjianYang/ZeroAoVoice-PSP/tree/master/tools/AddScnsToIso) and i don't know how to download these files. I only get some kind of code page. Also: How would i use this .cpp file if i somehow managed to download it. It doesn't seem to be an exe.

Also: "6. Extract voice files(.at9) from the Vita edition game and convert them to wav with at9tool."

Where do i find these .at9 files in the directory of the Vita game and how do i extract them?
