Re: [Linux] GUI discussion

That's actually not a half bad idea--in the config, we could have fields where the user enters the horizontal and vertical dimensions of their host system's screen in inches, and PCem could then use that to calculate the window dimensions in pixels that would correspond to various standard classic m...

Re: [Linux] GUI discussion

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 able to capt...

AGI stalls?

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 seeing any mention of...

Re: Issues with EGA emulation

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...

Re: Issues with EGA emulation

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...

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.

Re: [Patch] CGA monochrome & selectable mono display

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.

Re: [Patch] Add NukedOPL

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...

Re: [Patch] Add NukedOPL

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...

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!

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?
