The regular feature connector actually works pretty well in this regard, but you can't use high/true colour modes in DOS. The standard feature connector can pass 16 and 24 bit pixel values, it is done using more bus cycles. That's how, for example, my 3DO Blaster is able to work with 16 bit color …

Hi, I have put together a kind of weird system for playing DOS games. They play, unscaled, in the center of a giant 384x256 pixel LED display. This works great for most old DOS games that are lower than that resolution. But the DOS interpreter itself is running in I think, 720x480. The scaler I have …

Single ported memory is mostly fine for dual use with CRT controller/graphics rendering in the chip. It is the responsibility of the memory controller in the graphics chip to arbitrate access to the memory and not "starve" the CRT controller.

One thing I want to put to rest about the 3D Blaster VLB - there are 6 memory ICs so I wondered, why do people say it has 2MB. The answer is... because it has 2MB. Four of the chips (the lower ones) are 8 bit fast page EDO ram. Siemens HYB514171BJ-60; 256k × 16-Bit Dynamic RAM x 2 = 1024k SEC …

Ironically, though, some old 16-Bit Windows applications do run much better on Windows NT/2k/XP. Like some of the pre-Windows 3.0 applications, which Windows 9x refuses to execute (except if patched with Mark30 etc.) That's because these have a dedicated VM that runs a stripped-down copy of Windows …

Thanks for posting this I didn't realise that a patch existed - I'm a Millennium fan but aren't using mine currently, mainly because of this issue. I'll give this a try. No problem. Even with the scroll patch, you will need to set the border color to 0 if you have the palette problem. (B+F10 cheat)

My favorite card in my PII DOS development machine is my Matrox Millennium II. Unfortunately it doesn't run Keen well. Today I was able to fix that. The first issue is the color palette is all messed up. It turns out this is an issue with how the card implements the EGA overscan/border color. That …

I have tried to switch to the low resolution by F9 in the demo version without /3dblaster. It has done, than I have exited and start with /3dblaster. I planned to set to low res here too, but now starts in low res by default. And at last I see something, but everything looks which works looks full …

Which menu has you started? How get you exactly textures? (I press space three times and the game starts.) Glad you got it running - I looked around the menu without running it using /3dblaster, and tried some of those things while I was running it with /3dblaster. Everything was so blocky, that …

Yeah there was no text in the demo. I think they never finished it. Edit: by it, I mean text rendering with CGL. Regarding the artifacts from the Permedia + Delta, I got something like that when I had “Assign PCI IRQ to video card” disabled in the BIOS.

OK, I have tested with 3D Blaster VLB with HOTCGL environment (all the four CGL driver for 3D Blaster VLB in that directory).

Over the years I've developed a few patches. I always redistribute the patched binary. I think it would be nicer to use a patch tool that verifies a binary CRC first, then applies a plaintext patch that is just replacing bytes. Is there anything like that for DOS that works reasonably well? Thanks
