Maybe try the UniVBE driver from this website (it's not "that" UniVBE). It seems to support your chipset, so you might give it a go. But like others have said here, ISA will be a severe bottleneck (and probably other pats of your system as well). Paradise PVGA1A, WD90C00/10/11/20/21/30/31 https:// …

Isn't this video card too slow for a Half Life? I have a laptop with a 486 processor equipped with a WD90C24A graphics card chip that is manufactured a year later than yours. It's slow on 640*480 mode, 320*240 would be 4 times faster I expect, since video is a serious bottleneck here, combined with …

Hi ! I have ISA VGA card with WD90C31 chip 1mb, I want to achieve 320*240 16bit color mode for half life with it, it is not an option in game's resolution selection menu, software mode. Minimum resolution available is 640*480. I know that 320*240 is selectable if it is available, because some of my …

1600x1200 is an integer scale of 320*200 and aspect correct ;) Wow, nice, I was fixed on equal scaling for some reason. Thanks! This expands possibilities. Original post changed. Any more laptop models for that, besides the one above? Though my 1280*800 had also perfect scaling with text mode, …

may I ask why you're so fixated on a 1280x800 resolution? It's integer scale of 320*200, not aspect corrected I understand, but i like it that way. Dos games look very good to me. The thing is, my old laptop from 2008 is core2duo 2ghz, 2gb ram, 1280*800. I always wished it had paralel port, floppy, …

it's unlikely that you'd find a laptop with a 16:10 display and a floppy drive, if anythig some model with interchangable drive bays that is compatible with older drives but then you'd lose the CD drive. Thank you. I was too thinking that way now. Can I really change cd drive with floppy drive? I …

Thank you. True, I also expect it to be Pentium M, from available laptops for sale. The thing is, I am not sure if such laptop exists. Thats why I need exact laptop models with these specs so I can find it better.

CGA intensity
Posted on 2022-05-16, 06:57
Hi. In cga pinout there are 4 color pins, R G B I. Does the intensity bit make existing color brighter or mixes it with white? For example: rgbi=1001 Is this seen as a brighter red or a mix of red+white on screen? Thanks n advance.

Rob, yes, I set machine=cga. F12 works for me with one of the executables on r3804 commit page. But not on plain 0.74-3. Can you please check 0.74-3 and verify that it works? I would prefer to use a stable mainstream version rather than pick one of many other builds.
Re: DosBox and CGA

Rob, F12 doesn't seem to work for me. I am confused. Is there some specific dosbox version for this to work, or last version is good 0.74-3 ? I am on windows os.

Hi. Few questions about dosbox and cga after reading this: https://www.dosbox.com/wiki/Configuration:DOSBox 1. when setting machine to cga, does it emulate cga as it would look on rgbi monitor or composite monitor? Is there a way to fix the output to only one? 2. when machine is set to cga, scaler …

Hello, you need to read from that memory location first in order to fill the latch registers. A zero in the bit mask register means that the associated bit of the latch registers will be written back to that memory location. If you got zero in the latches, then zero is what will be written. That …

Hi. Is it hard to make an option for dosbox to make it scan 4% less than it normally should, so people with 768lines lcd can enjoy pixel-perfect scaling at fullscreen? For example: text mode 400lines, will become 384lines and fit perfectly on 768line screen by doubling, And, 200lines game, will …
