DOSBox Pure vs DOSVAXJ3

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.

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.
