Hello PSXHAX, today PlayStation 4 Developer Zecoxao has conveyed a new tutorial on how to decrypt and dump PS4 games (EBOOT, PRX, SPRX).

Previously, he made a tutorial on How to Dump and Decrypt Usermodules, which is a continuation on this topic he brings today.

There was a mistake on the tutorial, but @zecoxao had got it fixed, so everything should be okay now. Lets jump straight into this tutorial.

To roughly quote Zecoxao's Tutorial: [Tutorial] How to Decrypt and Dump Games (EBOOT, PRX and SPRX)

Requirements:

• ps4sdk precompiled
• elf loader precompiled or extreme-modding's elf loader.
• the payload source
• 1.76 console
• usb pendrive or external hdd (fat32 or exfat, exfat recommended)
• A preactivated online game or a purchased disc game
• The TITLE ID of the disc

Steps:

1. Compile the payload with the correct commands. Specifically for The Playroom (CUSA00001):

Code:

decrypt_and_dump_self("/mnt/sandbox/pfsmnt/CUSA00001-app0/eboot.bin", "/mnt/usb0/eboot.bin");
decrypt_and_dump_self("/mnt/sandbox/pfsmnt/CUSA00001-app0/sce_module/libc.prx", "/mnt/usb0/libc.prx");
decrypt_and_dump_self("/mnt/sandbox/pfsmnt/CUSA00001-app0/sce_module/libSceFios2.prx", "/mnt/usb0/libSceFios2.prx");
decrypt_and_dump_self("/mnt/sandbox/pfsmnt/CUSA00001-app0/sce_sys/about/right.sprx", "/mnt/usb0/right.sprx");

2. Start the game.
3. Minimize the game (PS Button)
4. Access elf loader
5. Let it load all the way until stage 5 and stabilize
6. Plug the usb stick or hdd on the rightmost port, near PS4 logo
7. Load the payload:

Code:

#listener
socat - TCP:my.ps4.ip:5052
#sender
socat -u FILE:path/to/DumpFile TCP:my.ps4.ip:5053

8. when it finishes loading (user return 0) unplug the stick or hdd and check inside. you should have the files in elf format on the root

PS: This is a continuation to the previous tutorial "dump and decrypt usermodules"
PSS: Do not forget that the games decryption require ABSOLUTE PATH due to rif management.
