Ar Tonelico Qoga : Knell of Ar Ciel [BLES01102]

Save game works now (only 1 save slot, though).

As for crashes I guess it should be tested in somewhat long play, at least several hours, cannot perform it with my low-end CPU (playing like this is a sort of torture).

Also, from what I see, there are much less graphic glitches with Vulkan, but FPS is greatly also lower.
