PCem could use some shadery action... (and maybe have monitor "emulation" from it by picking a list of simulated monitors and maybe with appropriate edid emulation and the sync errors/phosphor trail buffer/fade in/color pollution) Yes, that would be incredible. I've always wanted to be ab...

Excellent work going on here, loving this!

Good to know, thanks.

Quick question for Sarah: does the CPU emulation currently make any attempt to account for the latencies caused by AGI stalls? As I look at the "elements taken into account" and "elements not taken into account" lists at the top of codegen_timing_pentium.c, for example, I'm not s...

Glad to hear that. Let us know if the problem returns!

Xeon W3690 64gb RAM GTX 1080 Windows 10 x64 All I use PCem for is recreating my old AMD 386/40mhz, and the emulation is faithful to the point that my memory recalls and reacts instinctiely to the same lags, stuttering and timings of things like a certain part of a certain game, or compiling certain...

That's interesting, but still suggests something like an improper pointer or improperly defined/allocated memory or I/O somewhere in vid_ega.c or vid_ega.h, I would think. The weird probing that the IBM EGA BIOS does is likely hitting some rarely used port or memory edge case or something that the S...

Er, I don't think the budget is there to hire anyone. What a weird suggestion... :roll: Truth be told, I think the moderation here is pretty much fine as is. Things get kind of silly sometimes, but mostly it's all under control. I don't know that we need to be asking for more in that area from Sarah...

I am trying to retain the ability to run Windows XP and 7 as Windows 10 is limited in what it can do, especially for programs from the years 1997-2006. Sorry if this is a bit of a derail, but can you elaborate a bit on what "limitations" of Windows 10 you're worried about? I'm going to be...

This is actually a very old bug--I reported it years ago, before this forum even existed. PCem's EGA support has always been semi-functional and lag/crash prone for me, whether using DirectDraw or Direct3D. As you point out, this is entirely exclusive to EGA and has never affected CGA, VGA, or any o...

But in the initial post of this thread, didn't you say "it happens with any emulated graphics card"?

Has anyone done any further digging on the Warcraft 2 issue that was the original point of this thread? The conclusion seemed to be that this is a genuine PCem bug, but it's not clear whether anyone has looked into it further or has a clear idea of what the problem might be.

This additional patch does the following - Raise exception #6 when attempt to execute opcode 0xC6/1~0xC6/7 and 0xC7/1~0xC7/7 on 286+ processors. - Raise exception #13 when attempt to write code segment in protected mode. - 286 LOADALL instruction does not alter PE bit in MSW register when in protec...

Yeah, let's not go down this road. We've got a good thing going here, and it really shouldn't be too much to ask for everyone to respect the basic ground rules and refrain from engaging in shady behavior. Let's not fuck this up.

The difference between a monochrome EGA or VGA monitor and a color RGB one should be fairly self-explanatory, no?

Seriously, monochrome EGA and VGA monitors weren't very common, but they were a thing. I just thought it'd be fun to extend the monochrome CGA support to cover them.

See, questions like this: Ok, then what if someone releases nightly builds of PCem outside this site? You can't do anything to prevent so. Come on, this is just silly. Sarah is legally responsible for what's on her own site, not for versions of her emulator that other people put up on other sites. I...

I've got to say, it does make good sense to have a firm policy about not hosting any copyrighted material here. Lots of sites draw a firm line on that; this shouldn't be controversial. Can we stop wasting time with silly arguments about it? There are lots of other places to vent disdainfully about c...

Depending on your host machine and guest configuration, it's possible to get a very significant speed hit from NukedOPL. The accuracy is excellent, but of course that comes at a price. Battler's patch makes NukedOPL the default but leaves open the option to use the previous, less-accurate OPL emulat...

Okay, that's what I thought. So the conclusions upthread about this not being a PCem bug were mistaken, then.

Good thinking including that option to switch back to the original OPL3 emulation, with NukedOPL as the default. Last I checked, the speed hit was considerable enough to be an issue when emulating faster machines, but NukedOPL's improvements are major enough to demand its use in all other circumstan...

Yeah, this is pitch-perfect. Thanks to all involved! It would also be really cool to be able to add support for monochrome EGA and VGA monitors, though I'm not sure how much work would be involved in getting that working, realistically speaking. Does anyone know?

I'm a bit confused--on real hardware, doesn't Warcraft 2 run just fine with cards like the ATI Graphics Pro Turbo and Phoenix S3 Trio64? I could swear I remember playing it on a pretty wide variety of systems of that vintage, back in the day. Am I misremembering that, or am I misunderstanding what t...

Sounds good. He did a fair amount of research on those colors and they're probably about as good as we're ever going to get without going much more in-depth on emulating different individual monitors etc. Well done!

Wow, this is fantastic to see! Great work, basic2004. I've been looking forward to something like this for years! Hopefully it won't be too difficult to squash the HGC-related bugs that appear to have been introduced by revs 733/734. I see this was ported from 86Box. Battler, can you say anything ab...

I guess we have to wait for the S3 Trio64 emulation to be complete. I'm a bit confused about this comment. I understand that the Number Nine Trio64 emulation is incomplete in various ways, particularly insofar as that board does differ in some ways from a standard Trio64, but what about the Phoenix...

The Schneider EuroPC uses a Siemens 8088 with some unusual clock speed options. It certainly does not support an 8086. I've corrected the CPU options in this patch, as well as the name of the machine as displayed in the list.

This is great, thanks Sarah!

You're not seriously asking Battler to go file the bug report, are you? What possible reason could you have for not just doing it yourself?

Sorry, I wasn't clear. I know about the --config switch. I was just saying that, because we've got that switch, the proposed change wouldn't prevent people from booting straightaway at launch if that's what they want to do. I don't really see why a selector window or "home screen" of some ...

Yeah, I've got to say--I've always found it a little odd the way PCem starts booting a machine immediately upon launch. Given that most users will be juggling multiple emulated machines, it would really make a lot more sense to have a config selector come up first as the default behavior. The abilit...
