And here, for your downloading pleasure, are the brand-new soundtracks for Rockman 4MI 1.00, containing all songs! The "Gamerip" contains music ripped directly from the game, and the "Source Music" contains the original vresion of each song from the game it's from. You can choose MP3 or FLAC, whichever you prefer.
Gamerip 1.00 v8 and Source Music 1.00 v9 contain a few corrections from earlier releases; see the changelog.
The Source Music album contains four songs from the Game Boy Advance. I used a program called GBA Mus Riper to produce high-quality rips of these tracks. If you prefer the lower-quality, but more accurate GSF rips, you can get them here.
I recently switched from using Mediafire to Mega. Mega allows me to upload a folder and have any user download the folder as a zip, or individual files as desired. As such, the Music Upgrade Pack is no longer necessary. Use the changelog to figure out which tracks you are missing or need to be fixed, and download those tracks from Mega.
