Due to the Front Mission 3D Remake (released in 2022), I can't host any music files here for the Front Mission games. I need to direct you to other places for the soundtracks.
Square Enix hasn't uploaded the Front Mission soundtrack to any official platforms. Rather, here's a shortcut to find soundtracks that fans have uploaded to YouTube.
The best place to listen to Front Mission fan music is at OverClock ReMix. They have also uploaded their music to YouTube.
MIDI music is a relic from the early days of the Internet when it was the only music we could download with our slow dial-up connections. It's fan music because MIDI files are made by people playing the songs on electric keyboards. The #1 website for video game MIDI music still exists today: VGMusic.com. There you can download Front Mission's entire soundtrack in MIDI format.
Here are some album covers for the soundtrack. The first one is the official cover. The other I made from the title screen.
Square Enix hasn't uploaded Front Mission 1st's soundtrack to any official platforms. And I'm talking about the PlayStation 1 version, not the 2022 3D Remake. Rather, here's a shortcut to find soundtracks that fans have uploaded to YouTube.
Here are some album covers for the soundtrack. Some official ones and others made with box scans.
The fan base has gone a long way with emulation. In the early 2000s, they came up with 'extracted game music' (a.k.a. chiptunes). They extracted the programming of the music from every classic video game and built digital soundtracks with them. With special music players, you can play these music files as if they were MP3s. And they're far better quality than MP3 because it's the actual programming of the song that you're listening to! In this realm, Super Nintendo music is under the 'RSN' file format and PlayStation 1 music is under 'PSF'. Music players that support RSN and PSF can be found on any device: Windows, Android, iOS, Mac, and Linux.
My favorite feature about this music is how small it is. Front Mission's RSN soundtrack is around 300 KB while an MP3 soundtrack is around 400 MB! So you could quite literally have hundreds of classic gaming soundtracks on your iPhone or Android phone, and barely make a dent in your phone's storage.
If you want to learn more, read my tutorial for Extracted Game Music. My tutorial also provides links where you can download Super Nintendo RSN music (for Front Mission SNES) and PlayStation 1 PSF music (for Front Mission 1st). Extracted game music can be converted to MP3, too. My tutorial provides directions on that process.
