DosKit vs MS-DOS Player

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.

MS-DOS Player is a free command-line emulator for running 16-bit DOS-compatible commands in a Win32-x64 environment. It is aimed at text-mode utilities such as file converters, compilers, assemblers, debuggers and text editors. DOS programs inherit Windows environment variables and can access host file paths directly. The Windows archive provides binaries for emulating 8086, 80286, 80386, 80486, Pentium 4, NEC V30 and IA32 processors. Documented hardware includes up to 32 MB of RAM, LIM EMS, serial and parallel I/O, keyboard and mouse input, timers and text display. Virtual COM1–COM4 can connect to host COM ports, with a maximum baud rate of 9600 bps; parallel output is written to a timestamped .PRN file in TEMP. A 16-bit command file can also be embedded in a 32-bit or 64-bit executable that runs without msdos.exe. The project is a fork tuned for the ReC98 build process, and its source is available under GNU General Public License version 2.
