What's the problem? Describe what went wrong.
Even on Dolphin 5.0, the game still runs slow sometimes around 70% with an unstable frame rate, there's also annoying HLE audio issues like crackling and stupid desynced distortions. Also, putting an Anti-Aliasing filter on this game doesn't work at all because I'm left with a dumb black screen.
Very disappointing that the first game I tested on Dolphin 5.0 already has loads of problems that need to be fixed.

P.S. I always run all games with Progressive Scan enabled and V-Sync enabled to avoid all of those annoying artifacts because I will never turn off those options.

What steps will reproduce the problem?
Just run the game using the default graphics and audio settings and you'll eventually see the frame rate and audio problems this game has, including that Anti-Aliasing bug that for some reason leaves the game with a Black Screen.
