Future graphics card emulation

[SarahWalker]

Given that you decided to make your first and at that point only post a request for stuff, I felt a little snark was in order.

Particularly as your request for the Trio3D suggests you didn't actually read this thread before posting.

I didn't see Trio3D in the original list. I didn't Ctrl-F either. I'll keep my requests to myself and ride out whatever comes. Thanks for your time.

Is the Matrox emulation still dead in the water? Even though it seemed really unique, simultaneously, I can see it being too big of a headache.

Also, I know someone mentioned the Number Nine Imagine 128, and that's basically a CAD card. But are there resources available for the Number Nine Revolution set? I'm only curious because it was, err, semi-successful, sort've...at least more so than a few others.

On the PCX1/2 front, this repository just happened

No tech docs, but the simulat2 (PCX1) and simulat3 (PCX2) folders have a lot of juicy bits for emulation reference in there as that's simulator code (among hardware registers, etc).

That's my question. I wonder if this program could somehow help emulate the graphics card (assuming its source code would be published)?

All 3DAnalyze does is inject overrides of caps and ids for Direct3D and OpenGL. It won't emulate anything. Way back then, it was mostly used to try to get DX8/9 games to work on DX7 hardware (often to trainwreck/slow results), and its hooking wasn't very stable.

The Xemu original Xbox emulator emulates a GeForce 3 and at a pretty good performance too. Would it be possible to make use of this code in PCEM?

No (or at least not at this point). Not only it's difficult to write the code to accurately emulate such complex piece of hardware, currently there are no GF3 datasheets available.
Note that the GeForce 3 chips we had in our desktop PCs and the one found in Microsoft Xbox are not the same. The latter is a GF3 derivative known as NV2A.
Bear in mind that in order to get the most out of GeForce 3 you'd need at least an entry-level Pentium 4 processor. Given how things stand it wouldn't make any sense to actually write the code for GF3 emulation at this point. Currently the fastest CPUs that PCem emulates are upper tier Pentium II and AMD K6-III processors, none of which are ideal to pair with GF3, not to mention that even the fastest Alder Lake processors could barely handle them (I can hardly go above Pentium II 400 with my slightly overclocked 12900 KF).
I would say somewhere around 2030 would be the more realistic date to get the GF 3 emulation done (provided that datasheets with sufficient information are available by then, of course).

And I have a question about the emulation of GeForce cards. Could these 2 repositories (+ nouveau driver source) help emulate these cards?
https://github.com/NVIDIA/open-gpu-kernel-modules
https://github.com/envytools/envytools
And is it possible to emulate hardware via High Level Emulation (it's not hardware emulation, but always something)? Because if so, maybe the TeknoParrot source code would help? - https://github.com/teknogods/OpenParrot There were also modified drivers for GeForce cards (X-Treme G for newer cards and Omega for older cards), but I don't know if this will help in this topic (probably none of these drivers has the source code disclosed)

No. PCem is a low level emulator where accuracy is a top priority so high level emulation is out of the question.
