Many of these modes may not fill to the edges of a VGA monitor. Other resolutions are stretched as follows :Ĭertain resolutions, like 320x240, need no aspect ratio correction, since that mode was used to ensure square pixels. If no scalers or aspect ration correction settings in DOSBox are used, 320x200, 320x240, 360x200 and 360x240 resolutions are not scaled. Any aspect ratio correction from DOSBox has been removed. Mode 12h - 640x480x16 (60Hz, all other VGA modes run at 70Hz)įor the list of games, I have taken my own screenshots with DOSBox. Mode 11h - 640x480x2 (intended for monochrome analog VGA displays, MCGA compatible) In addition to supporting all the mode EGA supports, the standard, BIOS Supported VGA graphics modes are : Mode 10h - 640x350x16/64 (can display 16 colors from palette of 64 colors, requires color 350-line monitor) Mode 0Fh - 640x350 mono (intended for monochrome MDA monitors) In addition to supporting all CGA Graphics and Text Modes and the MDA Text Mode, the standard BIOS Supported EGA graphics modes are : Once people figured out how to manipulate its CRT Controller Registers without destroying their monitors, all manner of resolutions became possible. While there are a few games that use oddball EGA resolutions, custom resolutions really came into play with VGA. In this post I will identify other games that use non-standard resolutions. However, in my previous post I discussed how the classic DOS pinball games use Mode X resolutions. DOOM at its original resolution without any scaling or enlarging.Īs I mentioned, these settings are my personal preference, so you may want to experiment to find settings that look good to you and give you the performance you want.I have already indicated in several posts that 320x200 was generally the resolution for DOS games. It’s amazing how much information game artists were able to cram into so few pixels. Just for comparison, here is DOOM at its original resolution. DOOM enlarged with no enhancement or scaling. The results vary depending on what’s being displayed on the screen, but something is better than nothing. Notice how the large red numbers in the screenshots below are pixellated in the first image but smoothed out in the second image with hq3x scaling. hq3x scales the image up 300%, but it can make things look a bit “cartoon-ish” because it smooths pixellated edges. This will depend on your personal preference and the speed of your hardware. Right after that I like to change scaler=normal2x to scaler=hq3x. To do this I change the aspect=false line to aspect=true. Once the output is set to ddraw, we can enable aspect correction and scaling. Some DOS resolutions do not use square pixels, so aspect ratio correction keeps these games from looking “squished” on the screen (old CRT monitors did not have a fixed number of pixels, so this was not an issue back in the day). Next I change output=surface to output=ddraw to allow for scaling and aspect ratio correction. If your monitor is different, be sure to use its resolution (e.g. Open the nf file via the Start menu.įirst, I change the line that says fullresolution=original to fullresolution=1920x1080, which is my monitor’s native resolution. These settings can be changed by opening the DOSBox Options from the Start menu. The nf file controls how DOSBox displays old games and software. Compared to today’s high-definition games, DOS games used low resolutions, so playing old games in DOSBox on a modern LCD monitor or HDTV is not an optimal experience without some configuration.
