That is just bizarre! And I agree completely, I would not want sound effects at all. At least not in the sense that you mean. I can understand if it's something like, you know, the mario mixes 8-bit Eighties or Underworld Rock. But a blatant use of otherwise-unnecessary random sound effects muddling up the great tune that is Wave Man? Not for me.
What do you make of the youtube videos with music from the Complete Works series? (I guess they're remakes of the original megaman games with new styled-up music) To me it sounds like on some of 'em they tried too hard, didn't put enough thought into it, or just plain screwed up the tune and made it sound awful by going in a direction the original didn't warrant. ?? Somehow it almost seems like a bummer that guys with Chinese names we can't even begin to pronounce have better skill at writing original tunes on an ancient NES soundboard than new composers/remixers at Nintendo nowdays have at remixing them. LOL. Thank goodness for OC ReMix cleaning up their mess...although not all of their stuff is bad, but gosh, compared to OC ReMix's standard tunes, it's terrible stuff.
