Just to give you a different take on these songs check out this channel if you wish
https://www.youtube.com/user/Homie0staticI have to say the Shizz did a much better job than I did smoothing out the sounds when I tried a similar project.
The ones on the second channel do not have the extra sounds that the Famicom produces via the VRC6 chip.
I wanted to try a different approach and see how the US version would sound with the import's harder, heavier drums.
Mine were done using only NES hardware friendly sound channels but I did not use the CVII drum or noise samples only the
Japanese port. Hope you like them as well.
Please excuse the crudity of my channel.
