How does a real Sony PlayStation 4 console really work?

[GAMEBOYADVANCETEMPORARY]

I want to develop a Sony PlayStation 4 emulator from scratch by using Visual Studio 2022 Preview Enterprise Edition but I don't know how or where to start.

I already know how to program and develop Visual C++ applications with Visual Studio.

But I must know how a real Sony PlayStation 4 console really work, how does a real Sony PlayStation 4 console reads a Sony PlayStation 4 disc and how a real Sony PlayStation 4 console plays a Sony PlayStation 4 rom/game from a Sony PlayStation 4 disc.

Is Sony PlayStation 4 documented somewhere?

The other consoles are not as secured and protected as Sony PlayStation 4 & 5 from what I read here, like Nintendo Switch and Xbox One.

This surprises me to hear that the Sony PlayStation 5 is almost identical to Sony PlayStation 4, because most Sony PlayStation 5 games are ray traced and unlike PS4 games and a PS5 emulator, unlike PS4 emulator, has to emulate the ray tracing efficiently and this is not an easy task.

Also Sony PlayStation 5, unlike Sony PlayStation 4, is SSD based and not HDD based and this means that a PS5 emulator, unlike a PS4 emulator, will also have to emulate the SSD part efficiently as well.

But if PS5 is really almost identical to PS4 then this is excellent because when there is a working PS4 emulator that can emulate most commercial PS4 games very well then nobody will have to wait many years for a PS5 emulator that can emulate most commercial PS5 games.

But of course that to play a ray traced PS5 game on PC always on 60 FPS, the PC must have a RTX GPU with at least 32 GB RAM and at least 8 cores CPU and a SSD drive storage, an expensive gaming PC, because no matter how much good a PS5 emulator will emulate all PS5 games, a strong, powerful and fast PC is still required to play ray traced PS5 games always on 60 FPS.

I changed my mind. I will view the source codes of existing PS4 emulators and I will try to improve them to make the existing PS4 emulators work better on PS4 emulation.

That's not what I meant.

A good starting point would be to help the guy out from a recent story in regards to PS4 emulation on wololo.

Become part of a group and build and learn from there.

I like your idea. But how to become part of a group?
