How To Dump, Fakesign, & Run PS5 Game Backups

By Alex Free

Changes: v1.0 - 6/3/2026

This tutorial will cover how to dump, fake sign (allowing any console including your own to run the backup), and test (without deleting anything before you know the game can even be ran as a dumped folder!) PS5 games and apps up to the latest jailbreakble FW 12.70. It works for any apps or games downloaded from PSN back when you were on the latest firmware that you’ve been hoarding all this time, as well as physical game discs. Doing this for a game installed from a physical game disc allows you to not have to put in the physical disc to play it!

Preparations

Dumping

Alrighty, so make sure the USB device is plugged into the console, and then fire up that game. Once it’s running, you need to send the PS5 App Dumper payload via netcat. The command is nc < <IP address> 9021 < <path to ps5-app-dumper.elf>. So in my case it was nc 10.0.0.174 9021 < /home/alex/Downloads/ps5-app-dumper.elf. A notification will appear saying the dumping is starting. You’ll get progress in the form of constant PS5 notifications as well as on your PC terminal.

Fake Signing

Once it’s complete, you’ll want to close the game on your PS5, and remove the USB device. Connect the USB device to your computer, and you’ll see in the root of it there will now be a folder named homebrew. Inside will be another folder, named after the title ID of the PS5 game or app just dumped, appended with -app0. Remove the -app0 bit at the end, so you have something like PPSA02530 (Pragmata).

Now with PS5 Make FSELF Recursive, give it the game dump folder as argument, for example ps5mfr PPSA02530. This will look through the game dump (which is already decrytped, PS5 App Dumper automatically decrypts as it dumps since v1.01 Beta), and fake sign the eboot.bin as well as any *.psx shared libraries that it finds.

Testing

So the dump is ready to be used on any Jailbroken PS5 that meets the minimum firmware requirement. You can find out what that minimum firmware requirment is by going into the root of the game dump folder and opening the sce_sys/param.json that is generated by PS5 App Dumper. Look for the string contentVersion. You probably also want to know what version you just dumped, also in sce_sys/param.json look for the string requiredSystemSoftwareVersion,. You should see something like 0x1270000000000000, which I imagine means minimum firmware 12.70 but I’m not 100% on that.

Now we need to test this out. The thing is, some games do not like being ran as a dump folder. So deleting the game (espically if it was downloaded from PSN and isn’t available as a physical copy) is a non-starter. Luckily, we don’t have to.

So for purposes of testing, your going to copy your fake-signed game dump folder to the root of your USB device. And then your going to rename the game dump folder to PPSA01234. Make sure the actual game is closed with the option button on the PS5 controller. Then make sure you delete that decrypted folder ending with -app0 in the homebrew folder of the root of the USB device (back it up on your computer before doing so). If you don’t delete it, shadowmountplus will find it and use it over the actual fake signed game dump in the root of the USB device, which will not let your game launch. Then finally, re-execute shadowmountplus, the command will be nc <IP address> 9021 < <path to shadow mount plus elf file>. So in my case it was nc 10.0.0.174 9021 < /home/alex/Downloads/ShadowMountPlus_1.6test11/shadowmountplus.elf. Wait for it to find your game dump. This will override the legit game installation in the PS5 home menu, so when you launch the game it will use the ShadowMountPlus mounted decrypted and fakesigned game dump folder instead of the internal installation. This is exactly what we want, because I don’t know about you but I currently don’t have multiple PS5s (let alone jailbreakable ones).

This is what I alluded to about in the begining about using a USB HDD. One way you can tell the dump is actually overriding the internal game is it will load up much slower. Better however is if you have access lights on your USB HDD or USB SSD. A final, nuclear option to prove this is working is you can copy your decrypted dump that isn’t fakesigned over, and when you try to lauch the game you will get an error as it is not fakesigned, further proving this works.
