Summary 07853: quarth: Sound tempo slightly slow
Description Quarth's music is at the correct pitch, but the tempo is slower than the actual PCB. The crystal for the YM2151 seems to be correct (with the pitch not being a problem), so it is likely the game ticks the sound engine via the vblank interrupt.
Steps To Reproduce Start game.

As far as I can tell, while the screen timings are incorrect in general (they should be identical to simpsons), the vblank itself is at the correct period.

checking the gameboy version of Quarth (has the same music), sounds exactly like the video, next check with the actual mame version and sounds very slow
