Sengoku Basara 4: Sumeragi [NPJB00688]

Its not playable completely. After u play couple of stages u might experience some sound bug. Music and voices will go silent and after some time game will crash. This bug is long time in this game already. I tried to use various options of settings, but nothing helps.
Also wierd graphic issues with zero antialiasing = blinking grass and some textures

True. Once this silence happen the game will 100% crush after you finish a stage. You can rarely do a single complete stage. This problem is huge that the game should not be Playable label yet.
