Is there a free brute force Save data equivalent for jailbreak ps4 so I can decrypt and hex edit?

[azakhan]

If not, is there a way for me to edit cheat menu codes? I don't want unlimited lives//ammo/energy etc which completely breaks the game, just to increase them some. (I may need some advice on how to fit the converted hex values in the code sometimes though, most of the time I manage it).

decrypt save using the system, hex edit or use ghidra to reverse engineer what you want to change. it doesn't seem very hard, but more a pita than say the ps3.

Do you mean Apollo ST? And how do I use Ghidra, could you link a noob guide?

 

[godreborn]

apollo, yes, to decrypt the saves, but modifying them requires ghidra or ida pro or something similar. you won't really find a direct tutorial on that afaik. it could take months to understand what you're looking at with ghidra. I think there might be a switch tutorial that may or may not be adaptable for the ps4. it's on these forums somewhere. I don't know where exactly as I'm not a member of the switch scene, so google might be helpful.

What steps to decrypt on the system?

 

[godreborn]

I've never used apollo, only save mounter, where you mount the save, let the system decrypt it, then copy and paste the contents over ftp to your computer. apollo would be easier, just never used it.

Oh I've been looking at apollo tutorials , haven't found anyone say about decrypt function. With save mounted you can't use USB?

 

[godreborn]

I'm not sure. I've never tried usb. problem is you don't want to leave a save mounted. I know it will be stuck in limbo if you turn off the console, but going into another app may have the same effect, just not sure.

So looks like I'll have to use S mounter. After mounting it and opening the folder, the 'dis.dat' is the decrypted save file?

 

[godreborn]

most likely. the files are not all named the same thing.

 

[azakhan]

most likely. the files are not all named the same thing.

Then how do I know when it's decrypted and which file it is I need after mounting?

 

[godreborn]

it wouldn't be in the sce_sys. any file outside of that is what you need.

 

[azakhan]

So any file apart from that one will always be only 1 definitely being the decrypted save file?

 

[godreborn]

yes, the sce_sys is also part of it, but that folder's primary function is to tie the save to your account. your account id is in little endian (byte reversed) at 0x15c iirc of the param.sfo inside of sce_system. with that being said, it's irrelevant to codes or anything. if you were to change ownership of the save, you'd leave that folder out due to that.
