Yes, I am aware that I have about 6 or so fangame projects currently in development at the same time. And yes, I am also aware that all of this is very ambitious.
+ List of projects I'm helping out with in some small capacity during my hiatus:
You don't "convert" chiptune music to something else entirely, it's not that simple. The music exists as it does, and has to be rearranged for a different set of instruments. This is especially time-consuming due to the limitations of a lot of sound chips most commonly associated with chiptune (such as the 2A03 of the NES), which tend to have limited arrangements due to the limited number of channels and can only deal in monophonic sound. Thus, chords and richer production would have to effectively be composed from scratch.
