This is all of course a very rudimentary GB emulator, not accurate at all.

It doesn't, though.

It sources roms from the Internet Archive: https://i.imgur.com/4bX7Oow.png

Legally dubious.

> ROM game commands

This phrase doesn't mean anything.

The game list includes games that do not support PlayStation Link Cable, so this has to implement netplay the same way other emulators do:

Both host and client emulate the game in sync, exchanging controller input

Edit: Seems like I was wrong about the latter, it runs the emulator on the host only, who sends video/audio from clients (and they send inputs).

My thoughts exactly, I didn't see anything on the paper addressing that.

I suppose it's assumed that with the contributions of this one, future work can be done to make it faster.

No idea what "some of the input" means, or why you thought "Low Resolution Input" is disingenuous?

It uses color, depth and subpixel motion vectors of 1-4 previous frames. All things that modern game engines can easily calculate. You didn't even need to read the paper to get this info, it's literally in a picture on the blog post.

Except Nvidia has published pretty much nothing about their method.

Did you read the paper? Or the benchmarks at least? In its fastest mode, it takes like 18ms. Not even usable in real time if you target 30fps.

Great start but definitely needs additional work to be usable in games.

I'll believe it when I see it :)

Anyway, PS4 emulation isn't very affected by this. Only thing it would benefit from would be that you'd be able to decrypt the firmware (and therefore run the emulator) without needing a hacked PS4 (like RPCS3 does with PS3 firmware).

Historically most people just pirate the firmware anyway (see: PS1 BIOS) so even there realistically it doesn't affect things that much. I consider this is a long-term, nice-to-have feature.

Still gotta emulate a very modern AMD GPU :) Just the shader translation (from GCN -> SPIR-V so it can be passed to the host gfx driver) is quite a challenging task actually.

Not to mention the fact that the PS4 has an APU and utilizes Uniform memory access (UMA). A simplified explanation is that both the GPU and CPU can read/write the same memory (with _very_ high bandwidth compared to conventional PCs), which will likely make optimizing high-end games that take advantage of this difficult.

Both games and the firmware are encrypted with several layers of encryption.

I know the dev and he isn't actually a student, his GitHub profile was just not updated.

Not to say that there aren't many university students interested in challenging topics like emulator development - I am one myself and know several other students in the emudev scene.

Anyway, university doesn't play a big role for most people, you don't learn many relevant things regarding that there anyway (other than bare essentials). You learn by doing. Just need to be curious enough to motivate you. That's true for most programming topics, not just emudev.

You provide the emulator with decrypted modules/libraries (dumped from a hacked PS4) that originally reside in the encrypted firmware .PUP.

I'm associated with PS4 emulation and the project, any other questions welcome.

How so? To maintain lower expectations & set yourself up to surprise people positively?

Except you don't need to have them _memorized_. You shouldn't. That's not the point.
