Re: Running Nox on retro machine

in Windows
Nox use 3d acceleration. I was under the impression it is 2D (ddraw). Nox does not behave well on my Windows 10 system unless I run it in a window with DxWnd, so maybe GOG has done something to their copy... Have you used dgvoodoo 2? Nope. There is a patch by Peixoto for Nox. I haven't tried it, …

Re: DOSBox-X branch

A Vision864 (86C864) driver does seem unlikely to use acceleration features found only on the Trio 64 (86C764), and a Trio 64V+ (86C765) driver would probably not use them as well. However, the S3 emulation in DOSBox claims to be 86C764, and my comment about draw command 3 is in reference to the S3 …

Re: DOSBox-X branch

I haven't seen any Windows 3.x games that use the COLOR_CMP feature, at least not yet. Related to DOSBox's emulation of S3 hardware acceleration, in various Win3 dialogs an "Unhandled draw command 3" log message occurs, which according to the Trio 64 spec is "poly fill solid". The absence of support …

Re: img to iso

in DOS
There are no open issues for Win 3.x in SVN, and it is working for me. The keyboard and repeating keys (seems to be what is referred to as not working, but not sure) are working within Win 3.x itself, games, and apps. I suggest an SVN build from the ECE site, as the EmuCR builds are known to be …

Re: DOSBox-X branch

A solution for Mickey's Space Adventure, and similarly afflicted games, with machine=pcjr in official source is to use a LOADFIX -88 command. It allocates the memory below the PCjr's video memory window, forcing the program image to load above the window. I fail to see how that fixes the game. …

Re: DOSBox-X branch

when tandy boots, its bios sets it to ALWAYS be -16kb because there are no bios settings, it can never change on bootup, it is always -16kb from top of real memory. According to the BIOS code, it seems that 16 kB is NOT subtracted if an EGA or VGA card is installed, which does make some sense. …

Re: DOSBox-X branch

Some observations I made years ago with Tandy 1000 BIOS and Tandy DOS 3.30 in PCEm: When configured for 640 kB of memory: the word at 40h:13h (memory size) is 270h (624 kB), the word at 40h:15h (true memory size) is 280h (640 kB), and these memory values do not vary as the result of video mode …
