If you're one of the few lucky enough to have a PlayStation 4 1.76 console then you may be spending some time with the recent method on How to Run PS4 Backup Games, and today @zecoxao shared on Twitter an updated payload for those who prefer to load their games or PS4 homebrew from USB Stick.

Essentially what it does is implements the necessary directory path changes from /data/CUSAXXXXX to /mnt/usb0/XXXXX in the payload, easy peasy right?!

He also notes in his Tweets (below) that only fat32 and exfat are supported at this time.

And some recent Tweets:

Thanks to @hyndrid for the news tip in the PSXHAX Shoutbox earlier tonight!

Over the weekend we saw a P.T. Game Backup Running on PS4 1.76 OFW, and similar to Zecoxao's Tutorial here's another by BurtE of the NGU FAM that may be easier for those struggling to follow.

To quote from BurtE on: How to play your game backups on retail 1.76!

Hi guys, Today I have a little tutorial for you 1.76 users shared by a friend of mine, in this tutorial you'll learn how to run you own game backups via The Playroom.

What you will require:

• 1.76 console
• socat
• elf loader
• cmd
• filezilla
• ftp payload
• netcat
• decrypted game modules of the game you're using
• filesystem of the game you're using
• kernel hooks patch

1. Replace the encrypted game modules with the decrypted modules
2. Turn on your PS4 and enable FTP Payload
3. Go to data and make a folder called CUSAXXXXX
4. Drag and drop the game filesystem that you're using with the decrypted modules into CUSAXXXXX
5. Once it has finished switch off console to clean memory
6. Switch on PS4
7. Start ELF loader on PC
8. Open cmd and cd to socat directory
9. Open the browser on PS4 and go to ELF loader
10. Once it has got to stage 5 and its stabilized then execute this command in your socat cmd window
11. If it executes correctly without out of memory error then run listener with
12. If a cmd window comes up and says started successfully at the bottom then minimize browser with ps button and run the playroom

Recently Sony blocked the PS4 WebKit Playground on 1.76 consoles for those not using a proxy, and since the initial release through more recent revisions PlayStation 4 developers continue to adapt and update it with the latest being the PS4 Advanced WebKit Playground for 1.76 redesign from 0x199.

Check it out here: PS4 Advanced WebKit Playground for 1.76 / ELF Loader

Among @0x199's other work is a PS4 Firmware Version Detection JS / PHP Script and more recently a PKG Merge compiled version of Tustin's original PS4 Tool.

Cheers to @raedoob and @X41 in the PSXHAX Shoutbox for the news tip!

Using the Minecraft Trial on Retail PS4 Tutorial as a base after Playable Teaser was decrypted and extracted uncovering PT's resource files, PlayStation 4 developer @zecoxao announced on Twitter that P.T. is now running on PS4 1.76 Retail Firmware with a demonstration video via José Coixão on YouTube and a grid screenshot of the first graphical PS4 homebrew!

Zecoxao also confirmed that games don't require patches anymore, the payload below enables P.T. and should allow other games (check the PS4 Games List Minimal FW List) to run noting that this was tested in 3 games thus far: P.T., Angry Birds and MGS: Ground Zeroes.

Spoiler

He also reiterates the file structure is /data/CUSAXXXXX/<game structure with decrypted eboot and modules> and to run the backup games simply set them up with the kernel hooks following the guide, and when you see "started successfully" in the netcat command line you'll know the payload was ran successfully.

Finally, he stresses that ALL save games will be redirected to the Playroom...
