DOSBox-X
What it is
DOSBox-X is a free, open-source emulator for running DOS applications and games on Linux, macOS, and Windows. It officially supports DOS-based Windows guests such as Windows 3.x and Windows 9x/Me. The project emphasizes general emulation and hardware-behavior reproduction, including DOS/V services and NEC PC-98, AX, and J-3100 systems. A graphical configuration tool and many virtual-machine options let users customize the environment. DOSBox-X offers up to 100 save slots and can save automatically for selected programs or at chosen intervals. Its emulated NE2000 adapter provides guest networking through PCAP and Slirp backends. Parallel-port printing supports real or emulated printers, including PostScript or PNG output, and can work with Printfil or WinPrint on Windows hosts. Launching host applications is disabled by default for security and can be enabled through configuration or a command-line option. Documentation is available in a wiki, with an issue tracker for questions and suggestions. Pentium 4 or newer hardware emulation is listed as a non-goal.
For and against
For
- Free and open-source
- Runs on Linux, macOS, and Windows
- Supports DOS-based Windows guests
- Up to 100 save slots
- Guest networking and printer emulation
Against
- Android support is unavailable
- Pentium 4 and newer hardware are non-goals
- Host application launching is disabled by default
- Focused on DOS software rather than modern systems
The verdict
DOSBox-X offers broad DOS compatibility with configurable hardware, networking, printing, and save-state features. Its stated limits make it a tool for legacy software and preservation rather than newer PC emulation.
Who it suits
It suits people running legacy DOS software, preserving historical systems, testing programs, or continuing DOS development.
