The GPU implementation is surprisingly simple

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

Yeah it works! The sensitivity is pretty low - it would be cool to have a control for this in the GUI

You can change the sensitivity from here https://i.imgur.com/1go67wZ.png

If I'm understanding this correctly this offloads the copyright issue by making it the users responsibility to upload a rom?

No one really talks about it but the first iPod had the same approach to letting people play their thousands of mp3 files (which I imagine 99% of were obtained illegally). Apple was eventually able to create a legal marketplace for mp3s but early days it was all napster/limewire/kazaa/etc

Obviously Playstation/Nintendo roms are not as prevalent but its an interesting thought?

It doesn't, though.

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

Legally dubious.

Could you expand on the ROM game commands bit? Does it mean that all actions are serialized?

> 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).

Relevant performance details:

A Titan V GPU, using the 4x4 upsampling, at a target resolution of 1080p takes 24.42ms or 18.25ms for "fast" mode. This blows out the 11ms budget you have to render at 90hz (6.9ms for 144hz), and it doesn't appear to include rendering costs at all...that time is purely in upsampling.

Cool tech but a ways to go in order to make it useful for VR.

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.

scanning through it for the clause that gives away what slight of hand was used to correctly get BERLIN from nothing. Suspects

In other words, the label "Low Resolution Input" on the blurry images is misleading. The image should be labelled "some of the input".

Vel0cityX · 5 years ago
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.

Isn't this literally NVIDIA's dlss? And it has already been productized.
Vel0cityX · 5 years ago
Except Nvidia has published pretty much nothing about their method.

Would love to add this to my game engine.
Vel0cityX · 5 years ago
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.

The PS4 isn't a PC at all though. It's missing a bunch of core components, it has different memory maps and instead of a traditional motherboard chipset, it has a separate ARM controller that does crazy stuff.

Checkout the Fail0ver video on porting Linux to the PS4. It's really interesting.
