DOSBox Pure vs DosKit

DOSBox Pure is a DOS game emulator fork that runs on Windows, macOS, and Linux, either as a standalone desktop download or as a RetroArch core. It opens ZIP and DOSZ files, DOS programs, configuration files, folders, and CD, floppy, or hard disk images. For gamepads, it can detect games and apply controller mappings, or let users map controls to emulated keyboard, mouse, and joystick inputs. Each content item has 10 save-state slots, though complex late-era DOS games may have problems and states depend on using the same game and video or CPU settings. Users can create an 8 to 1024 MB hard disk image and install an operating system from a bootable CD-ROM or floppy image. The emulated NE2000 network card cannot connect to the real internet. Graphics include 3dfx Voodoo PCI emulation, with OpenGL hardware rendering by default and a software option that uses more CPU. MIDI music can use SoundFont files or ROM files for MT-32 emulation. It is free to download; donations are welcome.

DosKit is a cross-platform foundation for running DOS applications through js-dos WebAssembly technology. It opens to an interactive DOS command prompt and is available as an installable Progressive Web App for desktop and mobile devices. After the first visit, service-worker caching enables offline use. URL parameters can load applications such as Second Reality and Impulse Tracker. Input includes standard DOS keyboard controls, including function keys and special characters, plus mobile touch controls. Audio output uses Sound Blaster and AdLib emulation. DosKit uses js-dos 8.3.20 WebAssembly and supports DOSBox and DOSBox-X backends. Its command interface includes pause, resume, mute, unmute, screenshots and filesystem read/write commands. WebAssembly and JavaScript are required, with at least 2GB of RAM recommended. Internet Explorer is unsupported, and iOS Safari versions before 15 have limited WebAssembly support. DosKit is free under the MIT License; js-dos and DOSBox are listed under GPL-2.0 licenses.
