Welcome to MMLShare, the site where you can edit, play, and share Music Macro Language (MML) for the NES right in your browser. This site's MML compiling features are backed by the latest version of ppmck, giving you total control over your NES sound. We've also thrown in Bucky's DPCM library of samples for everyone to use.
All you have to do is register an account and add a new track in the My Tracks section.
If you're not familiar with MML, check out The Wikipedia Page.
Please note that this site isn't compatible with the version of MML used in these games. I realize there's a strong desire to be able to play and share these songs, however, so I will try to address them sometime before the end of 2016.
