What is DOSBox?

DOSBox is a free, open-source emulator that recreates a DOS (Disk Operating System) environment on modern computers. It allows you to run classic DOS-based games, software, and utilities that no longer work on current Windows, macOS, or Linux systems. Originally developed for gaming preservation, DOSBox has become a go-to tool for retro gaming enthusiasts and those seeking to relive old-school computing.

Why Use DOSBox?

  • Run classic MS-DOS games (e.g., Doom, Prince of Persia, Commander Keen).

  • Emulate legacy software tools that require a DOS environment.

  • Create a retro computing experience on modern machines.

Installing DOSBox

You can download DOSBox from the official website: https://www.dosbox.com/

Installers are available for Windows, macOS, and Linux.

How to Use DOSBox

1. Mount a Folder as a Virtual Drive

To run programs in DOSBox, you first need to mount a folder from your system as a virtual DOS drive. For example:

bash
mount C C:\Games\DOS C:

This tells DOSBox to treat the folder C:\Games\DOS as drive C: within the emulator.

2. Run an Executable

Once you’ve mounted a folder and switched to the virtual drive, simply type the name of the executable file to run it:

bash
dir ← Lists contents of the folder cd game ← Enters the folder named "game" game.exe ← Runs the program (e.g., `PRINCE.EXE` or `DOOM.EXE`)

3. Automount and Autostart (Optional)

You can configure dosbox.conf or use a custom .bat file to automate mounting and launching a game.

Common DOSBox Keyboard Shortcuts

Here are the most useful keyboard shortcuts while using DOSBox:

Shortcut Function
Ctrl + F1 Keymapper (customize keys)
Ctrl + F5 Save screenshot
Ctrl + F6 Start/stop WAV audio recording
Ctrl + F7 Decrease frameskip
Ctrl + F8 Increase frameskip
Ctrl + F9 Quit DOSBox (instant exit)
Ctrl + F10 Capture/release mouse
Ctrl + F11 Slow down emulation (decrease CPU cycles)
Ctrl + F12 Speed up emulation (increase CPU cycles)
Alt + Enter Toggle fullscreen mode

Tips for Better Experience

  • Use Frontends: Tools like D-Fend Reloaded or DOSBox-X provide graphical interfaces for managing DOSBox settings and launching games.

  • Create Game Shortcuts: You can create desktop shortcuts to auto-launch games by configuring .conf files or batch scripts.

  • Save Configurations: Each game can have its own config file, allowing you to fine-tune speed and settings per title.

Conclusion

DOSBox is an excellent tool for anyone interested in experiencing or preserving classic DOS applications and games. It’s lightweight, easy to use, and well-supported by a vibrant community. With just a few basic commands and shortcuts, you’ll be diving into retro computing in no time.
