DOSBox Pure is a standalone application derived from the core of RetroArch, designed to simplify the process of running classic DOS games on modern systems. It allows users to load ZIP files, mounted CD and floppy disk images, and DOS executables. Available as a pay-what-you-want download on itch.io, it features a user-friendly interface and provides step-by-step instructions for launching games. Users must supply their own game files, which can be sourced from platforms like GOG. Key features include rebindable keys, gamepad and joystick support, save states, a CRT video filter, and touchpad mode. The application automatically assigns controller buttons when detecting the game and gamepad, with customization options available.
