As the title suggests, what started as porting Book 1's music for use in GFE1R turned into me porting the entire game's soundtrack. Of course all of them are free to use as long as you give credit.
In this download you will not just find .s files for every FE3 song, but you'll also find copies of the spcs I used to get the midis, the midis I ripped from the spcs, and format-0 versions of said midis with loop points set for every song. There is also a .ups patch included with this package. If you apply it to a clean FE8U rom you can listen to all the music in-game. All music is unlocked in the Sound Room and due to the way I worked with this rom to port the music every single vanilla song is overwritten and then some. Additionally, there's a few bonus songs in the patch not present in the download, though none of them are from FE3.
I rushed through a fair portion of the songs from Book 2 onward (I did Book 1 over the course of a few weeks, I did the rest in the past 24 hours) so if you find any mislabeled songs, songs that don't loop properly, etc. let me know so I can fix them! A few songs (~7) are borked, but currently it's almost 4 AM and I just wanted to get this out there.

Shoutouts to SimpleFlips
The rom I ended up using for this was just a random dumping ground for testing things prior to being used for this project, so credit to Trueblade1990 for the Master Knight animations that are still in there from me testing things
The people who stole mid2agb and released it online
@Pikmin1211 for encouraging me at the beginning
@7743 for making FEBuilderGBA, which made fine-tuning the music much, much easier and also for the technical support on Discord
@DerSlendy because you deserve a shoutout
@unuesu for teaching me the basics of GBA music in the beginning
Lastly, videos of a handful of the music tracks in-game:
This last once again an example of this being an old dumping ground for testing things, the third song in this video is (unfortunately) not included in the package:
