Found below are various files, usually in MP3 format, of themes heard in any Mega Man game. The goal of this archive is not to put the soundtrack of all the games available in both MP3 and MIDI format: other websites already cover those areas. It focuses on rare tracks and fan remixes. Several of the official songs available here have been ripped by myself.
Important notice: those files, even those in MP3 format, are all LEGAL. I wrote to Capcom about the matter, and I got this answer. Be sure to read that letter before e-mailing me about any legal issues. Remember: Capcom owns the full copyrights over the original material.
You can download these files and keep them for your private use. If you want to distribute them, such as posting them on your own website, please contact me first. Enjoy!!
