Mira is a payload and series of advanced tools for jailbroken PS4s. It’s a Homebrew Enabler that will let you run unsigned code, but it’s also many additional features that make it a pretty much complete Custom Firmware for the PS4, complete with a kernel debugger and loading of plugin (prx) files.
Main features:
- Homebrew Enabler (HEN)
- Emulated Registry (EmuReg)
- Emulated NVS (EmuNVS)
- Kernel Debugger
- Remote GDB
- System-level FUSE implementation (Experimental, WIP)
- Load sprx modules + IAT + Function Hooking (Thanks theorywrong)
- Mount and decrypt local gamesaves (Thanks ChendoChap) (WIP)
- Transfer files to and from the harddrive
- Implement your own kernel plugins (RPC using protobuf)
- Implement your own userland trainers (hooks included!)
- Dump your HDD encryption keys
- A bunch of other stuff

Note: Mira (uart kernel logging) out puts everything that’s going on in memory to a terminal.
