DOSBox vs DOSVAXJ3

DOSBox is a free, open-source DOS emulator for running older programs and games that may not run on newer computers. It emulates 286 and 386 CPUs in real and protected modes, along with XMS and EMS memory. Its graphics support covers Tandy, Hercules, CGA, EGA, VGA, and VESA, while sound emulation includes SoundBlaster and Gravis UltraSound cards. Users can mount floppy and CD-ROM images, including ISO and CUE/BIN formats. DOSBox also supports IPX networking through its internal IPXNET program and can emulate a serial nullmodem cable over a network or the internet. The site identifies version 0.74-3 as the latest version and lists builds or packages for Mac OS X, Windows, Fedora, and Debian, along with source code. Its game compatibility list uses statuses including runnable, playable, and supported. For untrusted files, the site recommends secure mode; that mode disables MOUNT, IMGMOUNT, and BOOT. DOSBox runs on Windows, Linux, and macOS, and the forum is the suggested place to ask about usage or a particular game.

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.
