Hello. I have what I think is a good idea for a rom hack, I was wondering if anyone was willing to take on the project. Am I even asking in the right place? I don't know if anything like this already exists.(i can't seem to find anything from google searches). So basically just a rom hack where the soundtracks are replaced with remixed versions. Example of tracks that could be used:

Could ask Luke for permission to use his tracks.

So how easy/difficult would it be to make a rom hack like this?
