Help Please, Trying to restore old backup for Pokemon Moon

Okay I have spend hours trying to figure out how I can get back my pokemon save back up, I used to use powersaves back in the day and have an old backup of my stolen pokemon game, I have a new cart and have gone through the process of hacking my 3DS, I have the backup save and everything, I just need to know how to decrypt or convert the save data so I can use my hacked 3DS to insert the save data into the game, if anything if someone could at least tell me of anyway to access my pokemon at all I would be forever greatful, I have pokemon on there from when I first started playing like 14 years ago.

again Thank You to anyone who can take the time to help.

I Have another Moon cartridge, I just need to know how to decrypt the data is all, I have pokemon editors and whatever, I just want my pokemon, even if its just a pkhex insert to anothet game.

I am using a hacked 3ds with homebrew capability so I can do any possible way to restore my pokemon collection, even if its just a copy of the pokemon files through pkhex or whatever.

 

I am willing to if possible use a program or something to just read the pokemon out of the file or at least make it readable by pkhex, then I can at least remake them.

Edit: I have seen online its currently impossible to re-encrypt the data and put it on another cartridge, I am fine with losing the save game, I just want my pokemon any possible way.

If I can at least make the file readable by a program that's all I need.
