What game are you trying to run?

 

[DeltaX]

Well i try Soul Calibur and DoA2. Well i get both work no problem anymore for that but! i got problems both game.

SC: When fight begins it's just blank until i put wirefrime then i can see something but it's very very slow like 30FPS and i think 60 are more like good =)

DoA2: Nothing else but rly slow that 30FPS.

So problems are why emulator are slow and second prob are why SC are blank when figth starts


EDIT: I did download nullDC and it works nicely so nomore help needed.... oh wait how i can see scrolling menu on SC?
