Dynasty Warriors 6 Empires [BLES00540]

I have been playing this game today.
I have found if you set spu decoder to fast interpreter with the recent updates to rpc3 you get a massive performance boost.

I already tested on this fast interpreter but still no appear anything on the screen is loading with FPS black screen. But does this game only work on Vulkan? does opengl not work at all? This is my doubt about this problem.

Well I have tried it on both and both seem as good as each other really. A little while ago, I can't remember what version, it started up really slowly and took ages for the screen to slowly fade in from a black screen,  it then was really slow but sped up as the game continued.

Are you getting to the title screen where it says KOEI or is nothing at all happening?
If nothing at all is showing I would suggest you have some major config error.
