rgb: simulates the phosphors on a dot trio CRT. tv: like 'scan', but with darkened versions of the data instead of black lines. scan: like 'normal', but with horizontal black lines. normal: nearest-neighbour scaling (big square pixels). To see comparisons between the different scalers, see Scaler. Specifies which scaler is used to enlarge and enhance low resolution modes, BEFORE any additional scaling done according to the Fullresolution and Windowresolution settings under. Scaler = none | normal2x | normal3x | tv2x | tv3x | rgb2x | rgb3x | scan2x | scan3x | advmame2x | advmame3x | advinterp2x | advinterp3x | 2xsai | super2xsai | supereagle | hq2x | hq3x (info taken from wikipedia:Color Graphics Adapter,, and ) Note that SVGA fully supports most CGA modes (except the 16-color composite mode), so you should be able to leave DosBox in SVGA mode and play most CGA games. (Can sometimes be selected as an alternate on some games).
If original resolution is less than desktop resolution, DOSBox will switch the screen resolution to the closest match requested by the game or application. Original is the game's default or chosen (through setup.exe or in-game menu) resolution. These settings are passed on to the SDL Library which handles low level things like input and thread priority.įullresolution = width x height | original | desktop Scale the application to this size IF the output device supports hardware scaling (i.e. You can often achieve a fair level of optimization by working with these setting, though for the most part leaving them at their default settings will create the best experience. You can define what resolutions are emulated, how DOSBox should treat errors or listen to your keyboard and mouse. This section contains all of the low level system settings for how DOSBox interacts with your real hardware. This file is also deleted after DOSBox is launched. You can find the nf by browsing Start > All Programs > Dosbox-/Temp/cfg?.tmp. The location is indicated by the DOSBox Status Window upon startup.
On 0.74, just go to the DOSBox folder and open "DOSBox 0.74 Options.bat" in order to open the configuration file (*.conf).ĭnf is created automatically in the Windows' user profile folder.
