Also for PC JP version of Zero, here's the modified voice scripts necessary to use the voice patch by ZhenjianYang. The rest of his patch can be found at
https://github.com/ZhenjianYang/SoraVoice/releases and the actual voice clips needed are at

The same method I used to fix these should also work for Ao assuming it requires it. (Saw some people claiming the google translated version worked with the voice patch without further modification needed but not sure if Guren's version will.)
edit 2-22: Fixed some of the character names I noticed being broken, Ry} -> Ryu, Plati$re -> Platiere, ^azy -> Wazy, No@l -> Noel, K{ken -> Kouken, K{ki -> Kouki, Garc_a -> Garcia, B`lz -> Baelz, G{fan -> Goufan, caf\\ -> cafe, clich\\ -> cliche, Pli\\ -> Plie, fianc\\e -> fiancee, Azer -> Azel, will fix any others if I notice as I play.
edit 2-23: Integrated script fix for the race scene (previously badly desynced) still needs further testing though, if it crashes or does something bad replace c140c with an old copy for now.
edit 2-24: More name updates. I'm gonna be doing this constantly as I play so if you see the file change without any other info it's probably just me finding another name or text encoding error and fixing it.
