DOSBox Staging vs DOSVAXJ3

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.

DOSVAXJ3 is a free emulator for AX, J-3100, and DOS/V systems, based on DOSBox. It runs on Windows, Linux, and macOS, starting in DOS/V mode; J-3100 mode is enabled through the configuration file. Japanese keyboard and text entry work through Windows or macOS IME or Linux XIM. Japanese fonts are included, and additional font files can shape the display like original hardware. The emulator boots Toshiba DOS, DOS/V, and other disk-image files. It supports long filenames and copying displayed text to the clipboard. The maker lists Windows 7, 8, 10, and 11, plus Linux and macOS. Windows downloads include 32-bit and 64-bit executable bundles and separate debugger bundles. Linux and macOS users must build and install SDL-IM-plus before building their versions. DOSVAXJ3 is listed under GPL v2, with source code on GitHub.
