PCem

I'm tempted to suggest that you add the sound that a real drive makes when its bearings finally wear out. Or the sound that old capacitors make when they finally burst and explode. Having had an old capacitor explode and hit me in the forehead recently, I suspect this has a high chance of triggerin...

That's a noisy hard drive you have there. The speed variation sounds pretty good to me. For floppy stuff, it might be (well, probably is ) worth looking at what I did for B-em, of which you've already found vestigial references. Code is at https://github.com/stardot/b-em/blob/master/src/ddnoise.c (u...

Most of my development is being done on a private dev branch, due to past history.

I believe the PC5286 did use IDE - Amstrad were using it as early as the PC2000 series.

640kb conventional + 384kb XMS looks right for a 1 MB machine. I don't know if the PC5286 enabled Shadow RAM or not; disabling it will give you more RAM, but run the machine a bit slower. If you were to get a real machine, you can dump the BIOS through DEBUG.EXE. The following commands should dump t...

This isn't currently implemented, but has been on my list for a while. Much of the infrastructure for floppy drive sound emulation is already present, I just haven't got round to finishing it off.

Could this be due to missing bios systems (i.e. nobody has dumped a PC5286, etc.)

Basically this - if the BIOS hasn't been dumped then it can't be emulated. I'd be interested in emulating these systems, though due to other commitments it would probably be some time before I could look at them.

3D lines aren't currently emulated because I never saw any software trying to use them. If you want to work on a patch to add them then feel free! If we can identify the nature of the erratic 2D line rendering then it should be emulated, yes. I wouldn't be surprised if this is a hardware bug; someth...

NE2000 was released in 1988, and is most certainly not a Windows only card.

The one that says ViRGE/DX in the name.

The ViRGE/DX should be fine. What drivers are you using?

Revs 1191-1193 fix the issues in Mills's post, as well as REN-93.EXE.

DOCVIEW is a different bug btw, relating to scrolling & split screen not being properly implemented in text mode. Again, fixes shouldn't be too difficult...

Yep, there's a bug. PCem isn't forcing a screen refresh on writes to the per-pixel scroll register (0x3c0 index 0x13/0x33), which is only obvious if the start address isn't changed and there are no writes to video memory that frame. The fix should be fairly trivial...

Admins must be neutral on their forums at all times.

Since when? I'm a human being, not a machine.

Fenix77 only joined last September, so wasn't around for the original nightmare. So it's not unreasonable for him to not be aware of any of this. But in general, the entire 'fork' experience was very unpleasant, and there's a reason everyone involved (with the exception of SA1988, who has been reaso...

I don't remember saying that you're not allowed to mention it. Just that given the history, it's quite likely to piss me off, so caveat emptor.

And once Sarah has done that, Sarah has a list of things to add/work on that's longer than a really big fucking long list. So feature requests will largely be ignored for the foreseeable future.

Turbo on the 8550u is 2.2 GHz, not 4 GHz.

Performance won't be brilliant, the 8550u only runs at 1.8 GHz. I'd guess around Pentium 90 or so would be about as fast as you could get.

Wow. That must have taken some dedication to integrate.

It's a non-trivial amount of work (mach32 is an ACCELERATED card, which is always fun), and it would be yet ANOTHER thing to add to my already extremely long backlog.

Oh, so you do read these forums occasionally. Is the issue with the voodoo 64 bit codegen known?

Well I know that I've been testing it a lot less than the 32-bit version. I'd advise using that if at all possible...

I think I will ignore any thread that starts with [REQUEST] from now on...

Please do NOT link to copyrighted material. I can't believe I have to keep saying this!

One day? Maybe. But it would be several years out - emulating even one of these cards would be a vast amount of work, and I have no plans to work on any of them in the foreseeable future.

Maybe locking the thread will get the message across.



It probably won't, but I can dream can't I?

MiraiMiracle's attitude has basically guaranteed that I won't be implementing _any_ of the requested any time soon...

Because neither chip actually shipped? Desktop Pentium MMX peaked at 233, 266 and 300 MHz chips don't appear to have ever been sold. There is a (rare) _embedded_ PMMX 266, but that appears to be the same Tilamook core as used by the Mobile chip.

Hi, new here. Thanks for adding me. I have a lot of them, please bear with me, they're pretty straightforward. I'd use a wiki, but can't find one. 1.) Do MMX Pentiums take more CPU to emulate? Yes - they're slightly faster than non-MMX Pentiums of the same clock speed, so they will take more host C...
