So, I watched @VerMishelb videos and I found CIU video which is modded.
As you can see, He use a custom sound which they scream for Sr pelo.
Also, someone uploaded Touhou version of CIU.
It was made by @OneWingLunarian.
Another video by @VerMishelb.
Take a look at this @InterAction_studios.
It’s NOT possible to mod the game.
Like CI Games.
On CIU they change fonts on the game files.
Edit:Alright. This is for private users.
they can mod CIU
He won’t share to public because of IA.
Which means it will get unfair advantage.
