Re: Cyberpunk 1984

Oh yeah, Biliński! See also "Kosmiczne opowiadania" - https://www.youtube.com/watch?v=nz_mLSg5I70 That computer is Commodore 16, right? I recall trolling Commodore fanboys with that video, as it proves that the compulsory procedure after doing calculations on such computers is to VERIFY THE RESULT! …

Re: why sb emulation require virtual 86 mode

ALS4000 provides SB16 (and SBPro in stereo) in real mode. The utility from Avance Logic is memory-resident, but there's also a third-party non-resident utility. Doesn't use PC-PCI connector (a.k.a. SB Link). But it does require chipset support. See also - https://www.vogons.org/viewtopic.php?f=46&t= …

Re: VESA mode programming from real mode

If I pick 640x400x256 as the display resolution, would it be a fair assumption that almost all VGA cards of 512kb and above that are >= VESA 1.0 compliant should be able to run it? Yes, even some of those early 256KB SVGA cards support 640x400x256. However, such cards don't support VBE in their …

Re: VESA mode programming from real mode

However, wasn't VESA VBE BIOS 1.x made to be called from Real-Mode and 2.x from Protected-Mode? No. All VBE versions support calling INT 10h from real mode. Protected mode is only necessary to access the linear frame buffer, as it's located far beyond 1 MB. And the linear frame buffer is optional.

Re: VESA mode programming from real mode

Yes, it's perfectly possible to access SVGA frame buffer in real mode. The video memory is in segment A000h, pixel format in 256-color modes is like in mode 13h, and the only difference is the need for bank-switching - the segment size is 64 KB, while the frame buffer in 640x480x8bpp is about 300 KB …

Re: Scrolling in WFW3.11?!

in Windows
Back in the mid-90s when I used Windows 3.1 on my 286 PC I always wondered.. : "What is that third mouse button for?" I mean, at the time, I barely used the button on the right, even. Back then I used Unix with X11, and got accustomed to using all three buttons - SELECT, ADJUST, MENU. I still can't …

Re: Scrolling in WFW3.11?!

in Windows
Turns out I was wrong, The Windows 3.1 SDK does in fact define WM_MBUTTONDOWN and WM_MBUTTONUP. No built-in applications use it, and very few other applications do either. :( WM_LBUTTONDOWN, WM_MBUTTONDOWN, WM_RBUTTONDOWN, etc., are about mouse BUTTONS, not about scroll wheels. And yes, there's at …

Re: Scrolling in WFW3.11?!

in Windows
Mice with scroll wheels came years after WFW 3.11 release, so they can't be supported out-of-the-box. I don't know about any third-party software for that, but I've never been looking...
