Since I saw no one out there did a proper tutorial on how to get SpotPass demons, I thought I'd do that myself. Includes demons from Fusion Packs 1 to 4. Reminder that adding the demons this way won't make them available for fusion, you'll have to purchase them from your Compendium.
Durarara! characters can be obtained by following the thread from @Annarasumanara. Searching on Google for the Durarara! characters will surely link you to the thread I'm talking about.

Spoiler: But how do I edit my save file?

It's pretty simple.
If you have a 3DS, you'll need Custom Firmware (CFW) to extract your save file (using either Checkpoint or JKSM), which should come as 5 files. The one we need is save0.dat. After transferring the file to your PC using an SD card reader or FTP, you'll open it with your hex editor of choice. I'm on Linux and I'm using GHex, but any hex editor will work for this.
Search for the hex codes below using CTRL + F (or the search function button), and replace the first three '00' values with 'FF'. This will enable the demon in your Compendium. However, we're not done yet, as we need to set at least Level, Speed and Moves for the demon, otherwise it won't show up.
If you just want the demon to appear in your Compendium as a Lv. 1 demon with no EXP, set it 'FF FF XX XX FF 01 32 04', where XX XX is the demon's ID, and nothing else. But if you want to configure the stats, EXP, and other things, you need to edit them manually:

FF FF 26 01 FF 45 2D 03 00 00 17 1A 11 15 5A 02
1D 01 09 00 19 00 20 2D 30 00 00 00 00 00 00 00

This is the hex code for a Lucifer Frost, edited according to a 103% save file I found around. Let's take a look at it:

Red refers to the enabling values for your demon. Any demons you want to enable NEED to have all these three values set as 'FF'.
Green refers to your demon's level. You'll need to have a hexadecimal conversion table on hand, since the actual values in the game will be converted to decimal values. So, if we have '45', in-game we will have Lv. 69.
Orange refers to your demon's Speed, which is an invisible value in-game that determines whether your demon gets an extra turn or not. By default, that value is '2D'.
Yellow refers to your demon's Moves, which is the amount of tiles it can move in combats. Most demons have this value set to '03' or '04'.
Blue is your demon's amount of EXP. I'm not sure how it is calculated, so you'll have to test values and see what matches your needs best.
Purple refers to your demon's stats, which are ST, MA, VI and AG respectively. These values are converted from hex to octal, so you'll need to have a conversion table on hand for this too. If we have '17' for example, in-game we'll have 27 ST.
Dark Orange refers to your demon's HP. This one is also a bit of trial and error, since the game calculates HP based on the demon's base HP and Vi. The formula for this one is Displayed HP = Base HP + (Vitality (Octal) × Factor), if you'd like to actually calculate.
Light Blue refers to your demon's MP. The hexadecimal value you put is converted to decimal (8 bit integer), then to a 16 bit integer that is displayed in-game, so you may want to look up a website to do that for you.
Brown refers to your demon's Commands. There are a total of three Commands you can choose, and each value corresponds to a specific move. Thankfully, I have all the Command Skills codes thanks to a cheat file in GitHub, and will provide them below:

Big thanks for @Annarasumanara for giving me a basic notion of how to work with this through their thread.

I wanted to know if it's possible to unlock the SpotPass Demon Fusion, because we can access them from the Compendium.

First, I tried to modify my save file with SpotPass Demon data from /r/SpotPass, but when I looked at those I only noticed the demon's ID in there, which seemed to only be used in Compendium hex section. I also tried to compare any hex that seemed different from each file of those data in someone's save file in the thread from @Annarasumanara and in /r/megaten - that has SpotPass Fusion Pack data - aaand there isn't any matches.

Second, I tried to copypaste some of the hex codes randomly from those save file to my save file. Yeess! The fusion seems to be unlocked. Here's what I found so far:

0x0A11 with 33 (if FE instead of 33, some demons from Triangulum is unlocked too):
Tyrant LuciferFrost
Touki Momunofu

0x0A12 with FC:
Megami BlackMaria
Megami Ishtar
Vile Seth
Divine Dominion
Fallen Dantalian
Fiend MotherHarlot

0x0C20 with FF:
Snake Yulungr
Dragon Fafnir
Divine Sraosha
Avian Kau
Avian Rukh
Beast Cabracan
Wilder Catoblepas
Genma Roitschaggata

0x0C21 with FF:
Fairy Spriggan
Fairy Troll
Tyrant Lucifuge
Kishin Okuninushi
Touki Ongyo-ki, maybe?? still invisble on mine
Touki Dokkaebi
Jaki Macabre
Femme Jahi, maybe?? still invisble on mine

My save file on 0x0A10:

On 0x0C20:

Seeing as I found nothing about this after searching on the internet, I wanted to share my finding somewhere. Hopefully, someone found this useful. Also, I hope someone will experiment further, because I'm too lazy to try all possible values.

For the record, I tested it when I have completed both Daichi's route, all characters have reached Fate 5 at least once (except Anguished One which the highest is 4), have done all Dera-Deka events once, defeated optional bosses up to Lilith (day 4) and I haven't done Triangulum arc.

 

[trucidate]

thank you very much for your contributions! (it also worked!)
as a side questions, is there a way to fix the Racial Skills for these demons after they are unlocked on the Compendium? I choose to have all of them at level 01, but they don't have their innate Racial, like "Evil Wave" or "True Phantasm"

EDIT: i am testing on my own save file as i have everything on hands for now. i didn't find any Race Skills on internet so far, so maybe it helps... i will update this more until the very last ones.

for example, these numbers should be added at this highlighted hex position for each demon:

i believe the only one missing is Mother's Love, the femme evolved skill. some seems to be replicated in different values, like "Agitate" but may be because some does evolve to another value in a certain level and some don't...? but, i think with this we can control every normal race skill on game now and correctly assign them to the spotpass ones. the next step would be figuring out how to make them be available as fusions (aside from Durarara!! characters) like @ranburk was exploring. anyway, this was fun!
