Hatsune Miku: Project DIVA F [BLUS31319]

Hatsune Miku Project Diva F 2nd crashes the same way btw....

Also this is interesting, Project Diva F DEMO crashes the same way in VS, meanwhile it works in rpcs3 normally ???? O.o

Why does the demo crashes, when its pretty much playable without VS?

Maybe you built in Debug mode? Build in Release instead. Make sure that any weird debugging options aren't enabled and the usual stuff.

I've built in Release mode, and im using default settings in VS.

Does it crash or it just get's Access Violation exception? If the latter - just disable it in exception settings in VS (menu appears then you are running debug).
RPCS3 uses those to intercept access to certain memory so they in 99.99% are fine.
