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.

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...
