ROM Hack eShop save files editable??

[OfficialBrony]

Hey so I got a little bored and decided to back up some game saves with JKSV within my home menu. I went to System Titles and got curious in what happen if I export the system save and the exdata.
So, this is what I got in the SysSave:

I have hidden files checked to see if the three folders had anything in them, they're completely empty.
The .bin files I am about to talk about says PowerISO File" because I have it set to read .bins a while back and they are still .bin files. PowerISO days the .bin files are not supported and I can kinda see why.

The setting.bin I think is just a save of what my settings are set in the eShop
The wishlist.bin is probably just a list on what games are in my list (pretty much nothing is on the list, thanks to Luma3ds and A9LH being installed)
And now the owned_titles.bin
I think it's just a list of the titles I have purchased with actual eShop funds. I was wondering if there is a way to open owned_titles.bin so I can see what's inside of it.

Anyways, let's move on to the exdata of the eShop.
These are what is in the folder:

They're just a file type, but I'm guessing the boss_bgm1 and boss_bgm2 are songs they play when you're in the eShop?? Correct me if I'm wrong.
I am not too sure what the boss_xml1 and the boss_xml2 files are.

Are any of these files editable?? Especially the owned_titles.bin??
Thanks for the replies!

I think I've seen *.boss files before as some sort of compression format used in DS roms.
The xml files might be xml files.

You should rename boss_bgm1 to boss_bgm1.bcstm and boss_bgm2 to boss_bgm2.bcstm, then see if you can open them in one of the many Bcstm players, like BrawlBox.

I will in a bit. I am at my mom's right now and not on my main computer (which is at my home) and she only has a laptop. She wants to use it and I said sure. Or unless I am able to play Bcstm files on my Galaxy S5 Neo

If you have your 3ds and can install unlegit Cias, then You can use VGMstream3ds

I have Luma and Arm 9 on my N3DSXL
Will I be able to play Bcstm files with that?

Yes, boss_bgm1 and boss_bgm2 are songs that play in the eShop, you can add a *.m4a extension to play them in a computer media player.
You can change the music using this app: https://gbatemp.net/threads/release-eshop-music-changer.404945/

So I did the eShop music changer, worked like a charm. Now I am wondering it the bin files are viewable...
Any ideas?
