Question about decrypting game binary

[Glibis]

Hello,
I'm a complete beginner when it comes to PS4 hacking. There is a game I'd like to decompile and study, but I heard that when dumping the game you end up with an eboot.bin that is encrypted. I'd like to know how hard it is to actually decrypt it (as i understand it, turning it into .elf file) and be able to study the decompiled code, all by using a jailbroken 9.00 PS4 (game came out last year).
I actually have no need to edit the elf then reinsert, I just want to study the code. Is that possible with the currently existing tools?

There are payloads that decrypt it then dump it so its same process just different game dump Payload

This was the tut I used back in the day to decrypt eboot.bin to eboot.elf should still work but I hosted my own payloads so i could change the game id not sure if theres a precompiled one for your game

It's not very hard anymore, when you dump the game, all encrypted files will be decrypted. If you have a fpkg eboot, decrypt it with unfself. To see how things work, use ghidra and one of the ps4 loaders on your pc.
