Developer bigboss (psxdev) has been diving in deep on the PS4 of late, the dev recently blogged about the PSVR reversing to open the headset for additional platforms, but on the PS4 a small building block was introduced! In the form of a library for 2D Graphics for homebrew devs called liborbis, its early but a start to something that hopefully evolves overtime, As mentioned in my opinions of the PS4 1.76 exploit, bigboss also showed off a Simple PoC Homebrew running on the PS4, the video can be seen below. So progress is being made and shows why v1.76 is a good window for development and hopefully this progresses well by time we see a public exploit for a current firmware.
