DOS-Emulator vs DOSBox Staging

DOS-Emulator is a free IBM PC emulator that runs DOS and is written in Rust. Source code is available under the MIT License, and users can build it with Cargo or download a prebuilt binary from GitHub releases. The README identifies macOS and Ubuntu Linux as supported hosts; Windows lacks the ANSI escape sequences required by its CLI dependency. The project is inspired by DOSBox but is not a direct port, and many features are implemented differently or absent. Only Game of ROBOT episodes 0, 1, 3, and 4 are known to be playable. Its command-line interface can quit, pause into a debugger, or open a keyboard-mapping tool. The debugger profiles instructions, inspects register-selected data, scrolls its overview, and supports continue, step-over, and single-step actions. The architecture separates video and input on a GUI thread from audio synthesis for Sound Blaster and beeper signals. The latest listed release is v0.1.0.

DOSBox Staging runs MS-DOS and Windows 3.1 software on modern Windows, macOS, and Linux computers through built-in MS-DOS emulation. Its main compatibility goal is PC Booter, DOS, and Windows 3.1 games released from 1981 to 2000. Default settings are intended to let most games and applications work without adjustment, and existing DOSBox configurations remain usable. Graphics options include CRT emulation, aspect-ratio-correct output, VGA and 3dfx Voodoo emulation, and custom shaders. Emulated audio includes Roland MT-32 and SC-55, FluidSynth MIDI, OPL, Gravis UltraSound, and PC speaker sound. Networking includes Ethernet through SLiRP and ENet modem transport. Host features include clipboard integration, physical CD-ROM mounting, high-DPI support, and Windows 3.1 seamless mouse integration. An optional HTTP REST API can inspect or modify emulator state, but it is disabled by default and binds to localhost; exposing it to untrusted networks gives them full control of the emulator. The project says it collects no personal information and makes no network connection unless initiated by the user. It is free for personal use, without warranty, and intended for low-stakes scenarios.
