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.
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 savegame directory, so be sure to do a backup before trying other games!
