The sad truth: . The PS4 lacks an SPU (Synergistic Processing Unit) emulator, so heavy Cell games fail.
The foundation of the entire process is a PS4 running a firmware version that has been successfully exploited. Currently, firmware versions 9.00 and below are the most common for homebrew development. Firmware 11.00 also has limited exploit support. A jailbroken console allows you to run unofficial software, including the homebrew applications necessary for installing custom PKG files.
