Summary	08546: nes [zelda2u]: Sounds frequency randomly going up and down
Description	As per attached sample, you can distinctively hear Link's sword flashes and parries going up and down in tone as the game runs. As per my hearing ability , it does not seem to affect music but I could be wrong.
Steps To Reproduce	Just launch the game and start making noise an any way.
Additional Information	Please rename attached file extension from .zip to .mkv , as mkv was not allowed for upload. Encoded with standard H264 codec for the sake of size as original, internal Mame recording was 250 Mb. Only recently noticed that glitch and It happens to impact as far back as v0.187, but I have no idea as to the regression version, if any.

The sound of Link's shield blocking is also off. It rises in pitch a bit, though it's less noticeable than the sword sound. Anyway, I think this is probably related to 05775.

And indeed I used an ambiguous wording with "parrying", I meant that both sword and shield blocks/parries seem affected, we hear the same thing. I first managed to notice it with the full-health sword energy throws, as the glitch often appears mid-way through the sound (as it happens in the provided sample) which makes it more obvious.
