Dosbox change window size – DOSBox, the beloved emulator for classic DOS games, empowers you to customize your gaming experience, including the window size. Embark on a journey to explore the myriad ways to modify the DOSBox window size, from configuration files to command-line arguments and scaler options.

With this comprehensive guide, you’ll discover the intricacies of DOSBox’s window size manipulation, ensuring optimal gameplay and visual fidelity.

DOSBox Window Size Customization: Dosbox Change Window Size

DOSBox is a DOS emulator that allows you to run old DOS games and applications on modern operating systems. One of the common issues users face is adjusting the window size of DOSBox to fit their preferences or the game’s requirements.

This article will provide comprehensive instructions on how to change the window size of DOSBox using various methods, including the configuration file, line arguments, scaler options, fullscreen mode, and aspect ratio adjustments.

DOSBox Configuration

The DOSBox configuration file, named “dosbox.conf,” allows you to modify various settings, including the window size. To change the window size using the configuration file:

1. Open the “dosbox.conf” file using a text editor.
2. Locate the following lines:
• fullscreen=false
• windowresolution=original
3. Change the “fullscreen” value to “true” if you want to run DOSBox in fullscreen mode.
4. Change the “windowresolution” value to the desired window size in the format “widthxheight.” For example, “640×480” sets the window size to 640 pixels wide and 480 pixels high.
5. Save the changes and close the configuration file.

Line Arguments, Dosbox change window size

You can also use line arguments to change the window size of DOSBox when starting the emulator. To use line arguments:

1. Open the command prompt or terminal.
2. Navigate to the directory where DOSBox is installed.
3. Type the following command, replacing “width” and “height” with the desired window size:

dosbox

• w "width"
• h "height"
4. For example, to set the window size to 800×600, type:

dosbox

• w 800
• h 600

Scaler Options

DOSBox offers various scaler options that can affect the window size and image quality. The following table compares the different scalers:

Scaler	Description	Advantages	Disadvantages
Normal	No scaling applied.	Accurate pixel representation.	Can result in a small window size or blurry graphics.
2xSal	Doubles the resolution horizontally and vertically.	Sharper image quality.	Can be computationally expensive.
AdvMAME2x	Similar to 2xSal but with additional filtering.	Smoother image quality.	Can be computationally expensive.
Super2xSal	Advanced version of 2xSal with improved filtering.	Excellent image quality.	Most computationally expensive.

The optimal scaler setting depends on the desired window size and system performance.

Essential Questionnaire

How do I change the DOSBox window size using the configuration file?

Edit the DOSBox configuration file (dosbox.conf) and modify the “windowresolution” parameter to your desired width and height.

Can I use command-line arguments to change the DOSBox window size?

Yes, use the “-window” argument followed by the desired width and height, e.g., “-window 800×600”.

Which scaler option provides the best balance of performance and visual quality?

The “hq2x” scaler offers a good compromise between performance and image quality.
