Re: [Suggestions]

IMO: 1. not trivial. 3dfx never released as much info on the V5 that the V3 and prior had. There also isn't any CPU in the world to LLE it well theoretically. 2. not practical (especially with regards to the current generations PCem covers and the OSes many would most likely use with this) 3. they'r...

Re: PCem v18 News (Was v17 Notice)

V18 will be switching to Qt This may regress XP/Vista/7/8/8.1 support. Several emulators moving to QT (PCSX2, Dolphin) gave up 7 because they had no choice in the matter when that decision's from upstream and/or develop on Win10/linux unaware of the platform regression creep issues. OTOH it's great...

Re: 2 pci Mutimedia video devices not recognized Windows 98

Windows 98SE does not ship Voodoo2 drivers. The Voodoo3 drivers do not provide functionality for the Voodoo2. You should disable the Voodoo Graphics checkbox when you've got a Voodoo3 anyway. Identity crisis aside, they work like two different beasts.

Re: Unable to compile on latest Raspbian

The latest Raspberry Pi OS's on aarch64 and that's an architecture that wasn't tested much at the time of v17 (even though an arm64 dynarec is present, the 64-bit Raspban being a beta with less driver functionality). The current development tree on github may have better aarch64 support.

I'd dial the guest down to 166-200MHz. Voodoo2 threads can also matter, and i'd stick to 2 for this. (Maybe turn the screen filter off to help. :'( ) Either that, or get the host past 4ghz.

Re: PCem performance on AMD laptop APUs

Games like Jedi Outcast and Jedi Academy run great on VMWare, but you would need a powerful CPU, if it exists, to run them with PCem. This is applied in real-life too.

Re: Best video card for Windows 98 16:9 widescreen Desktop

Banshee/Voodoo3 have the VRAM necessary to handle contemporary widescreen resolutions (1280x720, 1600x900, 1920x1080), however Win9x monitor drivers don't expose them. You'll have to Powerstrip them in, probably.

Re: can the amd 3d v cache emulate p3

Nevermind unemulateably slow Pentium IIIs when there's still other gaps (K5, MediaGX, UMC486, Rise mP6, Nexgen). We barely have CPUs that can scratch at the highest emulated celerons (disregarding emulation of cache penalties).

Re: Future graphics card emulation

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.

On the PCX1/2 front, this repository just happened

https://github.com/powervr-graphics/PowerVR-Series1

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).

Re: Emulating p3 with winxp?

Practically speaking, the SSE games that'd be requiring a minimum P3/AthlonXP would be late 2005 stuff also requiring GPUs far beyond feasible emulation (and also at this time, pixel shader 2 was starting to be seen as obsolete by some big developers already as nVidia pushes ps_30 hard)...

Re: Change of resolution with Voodoo 2 card + Pentium III emulation ?!

That's a different realm of usage though. Where PCem emulates, it'd have to emulate all the behavior that comes out of using the hardware, including the Voodoo2's incapabilities. It's not an ultimate turn-of-the-millennium game fixer, but can serve to fill compatibility gaps as time goes on, as even...

Re: Change of resolution with Voodoo 2 card + Pentium III emulation ?!

When I last tried it on a V2 it went into seemingly a rasterizer mode. Maybe it got support added in a later patch or something, but it definitely wasn't there for the demo.

also note the post dates. Blade of Darkness DOES work on PCem v17's V3 emulation fwiw.
