Nice, but cluttered.

I liked the NES sound at the start, that's unique alright. However, I have to admit that it sounded really cluttered in parts. It just had too much going on in several spots.
Also for being a battle song it was rather soft. Still, I enjoyed it, it just won't stick out in my memory either...If you clear up some of the clutter and make it a little more interesting I think it could blow us away.
The intro is excellent, don't take away the NES feel.
If you remake this song (Or if you already have I'll be willing to listen! ^.^)

nice

It needs a punch-in-teh-face intro, to get your adrenalin pumping, and definitely more craziness, but this is pretty good. Don't you love those spur of the moment, I'ma make a song, moments? I like the dramatic space about 1:20. Very at home there. It has an overall 8-bit theme to it, and I am drawn to that because I constantly play games with music like that. It's no FF6 Battle theme, but its good nonetheless. Could you try to make a FF6 battle theme? If you do lemme know!
