Megaman-esque Chiptune Song

Hey guys! I made this little diddy in Famitracker, I wanted to have it sound as faithful to the NES/Famicom as possible. Please let me know what you think! In my opinion, I'd like to have a little more original material after that second section before the intro theme reprises. 

Charming! VII chord can be substituted for a V chord sometimes and it would give a different edge for the melodic high points, like when the melody runs up to a high D. The progression is generally okay since it's so bouncy, but having this repeat constantly would drive me insane, personally XD I think variating a little more would help. Even having one portion have one chord off can make it sound like two distinct parts which is all you need.
 

Chiptune music always brings me back to my childhood days. This sounds great, like something straight out of megaman. 

oh i like it very much! goodjob :)
