Methods for Playing DOS Games on Modern Systems

There are several methods for playing DOS games on modern computers. The most popular and reliable approach is using DOSBox, a DOS emulator. We’ll also briefly discuss other options, including virtual machines and native DOS installations.

Method 1: Using DOSBox (The Recommended Approach)

DOSBox is a free and open-source DOS emulator designed to run DOS programs on various operating systems, including Windows, macOS, and Linux. It’s the most common and generally the easiest way to play DOS games. Here’s a step-by-step guide:

Step 1: Download and Install DOSBox

1. Download DOSBox: Visit the official DOSBox website (www.dosbox.com) and download the appropriate version for your operating system.
2. Install DOSBox: Run the downloaded installer and follow the on-screen instructions. The default settings are usually fine, but you can choose a different installation directory if you prefer.

Step 2: Obtain Your DOS Game

You’ll need the game files for the DOS game you want to play. You can obtain these in several ways:

• GOG.com (Good Old Games): GOG.com (www.gog.com) is a great place to purchase classic DOS games. They often come pre-configured to run in DOSBox, making the setup process much easier.
• Abandonware Websites: Numerous websites offer abandonware DOS games for free download. However, be aware of the legal implications and potential risks of downloading files from unverified sources. Scan any downloaded files with a reputable antivirus program before running them. Examples of abandonware sites include Abandonware Dos, My Abandonware and others.
• Original Disks/CDs: If you still have your original DOS game disks or CDs, you can copy the game files to your computer. This may require some technical knowledge and might not work with all games.

Once you have the game files, create a dedicated folder on your computer to store them. For example, you might create a folder called “DOSGames” on your C: drive and then create a subfolder for each game (e.g., “C:\DOSGames\Doom”).

Step 3: Mount the Game Directory in DOSBox

DOSBox needs to know where your game files are located. You “mount” a directory in DOSBox, which makes it accessible as a virtual drive within the emulator. Here’s how:

1. Open DOSBox: Launch the DOSBox application. You’ll see two windows: a console window and a status window.
2. Mount the Directory: In the console window, type the following command and press Enter:

   mount C C:\DOSGames

   Replace “C:\DOSGames” with the actual path to your DOS games directory. This command mounts your DOSGames folder as the C drive within DOSBox.

3. Change to the Mounted Drive: Type the following command and press Enter:

   C:

   This changes the current directory in DOSBox to the mounted C drive.

Step 4: Navigate to the Game Directory and Run the Game

1. Navigate to the Game Directory: Use the cd command to navigate to the directory containing your game files. For example, if your game is in a folder called “Doom” within your DOSGames folder, you would type:

   cd Doom

   and press Enter.

2. Run the Game: Once you’re in the game directory, you need to find the executable file that starts the game. This is usually a file with a .EXE or .COM extension. Common examples include DOOM.EXE, MONKEY.EXE, or SIMCITY.COM. Type the name of the executable file and press Enter to start the game.

   DOOM.EXE

Step 5: Configuring DOSBox (Optional but Recommended)

DOSBox offers a wide range of configuration options that can improve your gaming experience. These options are stored in a configuration file called dosbox.conf. You can access this file in several ways:

• Windows: In the DOSBox window, type config -writeconf dosbox.conf. This will create a configuration file in your user profile directory (usually C:\Users\YourUsername\AppData\Local\DOSBox). You can then open this file with a text editor like Notepad.
• macOS: The configuration file is usually located in ~/Library/Preferences/DOSBox [version].conf. You may need to enable viewing hidden files and folders to find it.
• Linux: The configuration file is usually located in ~/.dosbox/[version].conf.

Here are some common configuration options you might want to adjust:

• Fullscreen: To start DOSBox in fullscreen mode, find the fullscreen=false line in the configuration file and change it to fullscreen=true.
• Resolution: The default resolution in DOSBox might not be ideal for all games. You can adjust the resolution using the output=surface, output=opengl or output=overlay settings. Setting `output=opengl` generally gives best results. Also modify the `fullresolution=desktop` and `windowresolution=original` settings.
• CPU Cycles: Some games may run too fast or too slow depending on your CPU speed. You can adjust the CPU cycles using the cycles=auto setting. If a game runs too fast, try reducing the cycles by typing cycles=fixed [number] (e.g., cycles=fixed 3000). If a game runs too slow, try increasing the cycles or using cycles=max. You can also use the Ctrl+F11 and Ctrl+F12 keys within DOSBox to decrease or increase the cycles dynamically.
• Sound: DOSBox emulates various sound cards, including Sound Blaster. If you’re having sound issues, try adjusting the sbtype=sb16, sbbase=220, irq=7, and dma=1 settings.
• Keyboard Layout: If you’re using a non-US keyboard layout, you may need to adjust the keyboardlayout=auto setting. You can find a list of available keyboard layouts in the DOSBox documentation.
• Mounting on Startup (Automount): To avoid having to mount your game directories every time you start DOSBox, you can add the mount commands to the end of the [autoexec] section of the configuration file. For example:

  [autoexec]
  mount C C:\DOSGames
  C:

Method 2: Using a Virtual Machine

Another option for playing DOS games is to use a virtual machine (VM). A VM allows you to run an entire operating system within your current operating system. You can install a version of DOS (such as MS-DOS or FreeDOS) on the VM and then run your DOS games directly within the virtualized environment.

Popular virtualization software includes:

• VirtualBox (Free and Open Source): VirtualBox is a free and powerful virtualization solution that works on Windows, macOS, and Linux.
• VMware Workstation Player (Free for Personal Use): VMware Workstation Player is another popular virtualization option, available for Windows and Linux.

Here’s a general outline of the steps involved in using a VM for DOS gaming:

1. Install Virtualization Software: Download and install your chosen virtualization software (e.g., VirtualBox or VMware).
2. Download a DOS Image: Download an ISO image of a DOS operating system, such as FreeDOS.
3. Create a New Virtual Machine: Create a new VM in your virtualization software and configure it to use the DOS ISO image as the boot disk.
4. Install DOS: Start the VM and follow the on-screen instructions to install DOS.
5. Install Drivers (If Necessary): You may need to install drivers for sound, graphics, and other hardware within the VM.
6. Copy Game Files: Copy your DOS game files to the VM. You can do this using a virtual floppy disk, a shared folder, or a network connection.
7. Run the Game: Navigate to the game directory in DOS and run the executable file.

Using a VM can provide a more authentic DOS experience compared to DOSBox, but it’s also more complex to set up and configure. This method is generally recommended for users who are comfortable with virtualization technology.

Method 3: Native DOS Installation (For Advanced Users)

The most authentic way to play DOS games is to install DOS directly on a computer. However, this method requires dedicated hardware and a significant amount of technical expertise. It’s generally not recommended for casual users.

Here’s a brief overview of the steps involved:

1. Obtain a Suitable Computer: You’ll need an older computer that’s compatible with DOS. This typically means a computer with a 486 or Pentium processor.
2. Obtain a DOS Installation Disk: You’ll need a bootable DOS installation disk (e.g., MS-DOS 6.22).
3. Format the Hard Drive: Format the hard drive using the DOS FORMAT command.
4. Install DOS: Boot from the DOS installation disk and follow the on-screen instructions to install DOS.
5. Install Drivers: You’ll need to install drivers for your sound card, graphics card, and other hardware.
6. Copy Game Files: Copy your DOS game files to the hard drive.
7. Run the Game: Navigate to the game directory and run the executable file.

Installing DOS natively offers the most authentic experience, but it’s also the most challenging and time-consuming option. It’s only recommended for users who are deeply committed to DOS gaming and have the necessary technical skills.

Troubleshooting Common Issues

Even with DOSBox, you might encounter some issues when trying to run DOS games. Here are some common problems and their solutions:

• Game Runs Too Fast: Reduce the CPU cycles in DOSBox using Ctrl+F11. You can also try using the cycles=fixed setting in the DOSBox configuration file.
• Game Runs Too Slow: Increase the CPU cycles in DOSBox using Ctrl+F12. You can also try using the cycles=max setting in the DOSBox configuration file.
• No Sound: Ensure that the sound settings in DOSBox are correctly configured. Check the sbtype, sbbase, irq, and dma settings in the DOSBox configuration file. Also, make sure that your sound card is properly installed and configured in your host operating system.
• Graphics Issues: Try different output settings in the DOSBox configuration file (e.g., output=surface, output=opengl, output=overlay). You can also try adjusting the resolution settings.
• Keyboard Issues: If your keyboard isn’t working correctly, check the keyboardlayout setting in the DOSBox configuration file.
• Game Crashes: Some games may be incompatible with DOSBox or require specific configuration settings. Try searching online for solutions specific to the game you’re trying to run.
• Game Requires a Specific DOS Version: Some very old games require specific versions of DOS. If DOSBox doesn’t work, try a Virtual Machine with the correct version of DOS.
