Re: No CRT Emulation? Why!?

in PC Emulation
Maybe you guys could get a few ideas from my non-realtime (video processing only, no shaders) attempts at color/mono CRT simulations. https://www.youtube.com/watch?v=oMibMBPSO-o (various color CRTs) https://www.youtube.com/watch?v=DGAt3Y6Pxn4 (various mono CRTs) https://www.youtube.com/watch?v= …

Re: First platform game, everyone is wrong?

in Milliways
However, if you mention these new insights, some people will verbally attack you and call you a liar, revisionist or something along these lines. That happened to me a few times, too. It seems that people take these things very personal, and don't want history to be updated with new facts. Yea, I …

Re: First platform game, everyone is wrong?

in Milliways
I'd take unsourced release dates for this type of stuff with a grain truckload of salt. Some software lists have the year for this game as "19xx" or "TBD", so apparently the release date isn't very evident... also, for what it's worth, the only references to "TriSoft", "Tri-Soft", or "Tri Soft" that …

Re: Best CGA & Hercules monochrome games

[...] But you can't go down to 2 scanlines per character, because the maximum frame length will be around 256 scanlines, and even if the maximum vertical adjust of 31 can be applied, you just get 287 scan lines. The MDA/Hercules monitor won't sync to pictures with 287 lines. So how does the …

Re: Best CGA & Hercules monochrome games

Theoretically it shouldn't do even that, because the vsync frequency is constant whether interlace mode is on or off. Now that I think about it, that's not quite right: when interlace mode is enabled in the CRTC, it delays vsync by half a scanline for the odd fields, in order to displace the …

Re: Best CGA & Hercules monochrome games

I'm not sure how you could reliably auto-detect this however - very few 6845-type registers can be read for anything useful... and anything trickier (say, in combination with a display status register) may fry the monitor while getting you your result. ;) Maybe a better approach would be a visual …

Re: Best CGA & Hercules monochrome games

There were some emulators that (optionally) used different timings, but as I know little is known about their details. It is not hard to figure out, though, because there are really only three timing variants that make sense, namely the 640x300 mode, the maximally compatible 720x348 mode and a mode …

Re: Best CGA & Hercules monochrome games

The author of SIMCGA is still around on the VCFED forums, but IIRC neither he nor Sydex hold the copyright any longer, so while I might be wrong I doubt he could help. Same story as with Teledisk/Anadisk. Also I see no theoretical reason why this couldn't be done using a modern free assembler like …

Re: Happy 40th IBM PC

For the same occasion... anyone had a look at the results of PCjam? https://pcjam.gitlab.io/ Not all of these are new, but there's some neat stuff in there - although at least three of these don't quite run properly (or at all) on the original hardware. 😉

Re: 32-Bit is dead

If 32-bit is dead, it's in good company. The internet is pretty thoroughly deceased, too, but we still keep on using it. 😉

Re: Leak of Windows 11

Seeing exactly zero changes/additions that would make a meaningful difference when using the OS on an actual PC. Not very surprising, since that hasn't been anywhere near their list of priorities for over a decade. Why, it looks like they barely even bothered to make it substantially *worse* on PCs …

Re: Dominus: A New Font for DOS

Nice work! Let me know if I could add it to the collection at https://github.com/viler-int10h/vga-text-mode-fonts 😉 (Also, if you often edit fonts under DOS, feel free to check out my font editor for some neat features).

Re: My DosBox tools

Hi Dave, Good to see the new site. Appreciate the update - lots of these tiny utils will be very useful, not only in DOSBox (or DOS-on-Win64) but for my memory-limited XT as well. And lest I forget, thanks for writing ImageDisk. That just might be your most popular program as of late, but it's a …

Re: FastDoom. A new Doom port for DOS, optimized to be as fast as possible for 386/486 personal computers!

CGA doesn't have a genuine monochrome mode, Mode 5 still outputs colors when connected to a RGBI monitor (which it's what I'm currently developing for). Mode 6 is genuinely monochrome on RGBI, you'll just have to use pattern dithering. If you pretend that it's mode 4 or 5 (i.e. you write the exact …
