(Documentation request) Explain the emulator design

[hardBSDk]

I can't find a document explaining how this emulator is designed, based on what I saw on the README of the compatibility list it is a hybrid LLE/HLE emulator.

Each game is mocked to think that it is running on Orbis OS but translated to the host OS, thus there's no need for hardware emulation (which will have much lower overhead because PS4 uses a PC architecture).
