Running DOS Programs

Running DOS programs or games in DOSBox is straightforward once you have the emulator set up. Here’s a step-by-step guide on how to run DOS programs using DOSBox:

Mounting Drives:

Before you can run DOS programs, you need to mount the directory where your programs or games are located as a drive in DOSBox. You can mount different directories to various drive letters (like C:, D:, etc.). Use the following command to mount a directory:

mount [Drive Letter] [Path to Directory]

For example, to mount a local directory “C:\DOSGames” as the D: drive in DOSBox:

mount d C:\DOSGames

Navigating to the Program Directory:

Use DOS commands to navigate to the directory where your program or game is located. The primary commands include:

• dir: List files and directories in the current directory.
• cd: Change the current directory.

For example, if your game is in a directory called “Game” under the mounted drive D, use these commands:

d:
cd Game

Running the DOS Program:

Once you’re in the directory containing your program or game, you can execute it by simply typing the program’s executable file name (typically ending in .exe) and pressing Enter. For example:

game.exe

Replace “game.exe” with the actual name of your program.

Exiting the Program:

When you’re done with the program, you can exit it by following its in-game instructions or using common DOS commands like:

• exit: To return to the DOS prompt and close the program.
• Ctrl + F9: To exit DOSBox entirely and return to your host operating system.

Adjusting DOSBox Settings (Optional):

DOSBox allows you to customize settings for specific programs or games. For instance, you can adjust the CPU cycles, screen resolution, or sound settings within DOSBox by editing its configuration file (typically named dosbox.conf). To access the configuration file, use a text editor or a DOSBox-specific configuration tool.

Capturing Screenshots (Optional):

If you want to capture screenshots of your DOS programs or games while running DOSBox, press Ctrl + F5. The screenshots will be saved in the "captures" folder within your DOSBox program folder.

That’s it! You should now be able to mount drives, navigate directories, execute DOS programs or games, and exit them gracefully in DOSBox. Enjoy your journey into the world of classic computing and gaming nostalgia.
