The original
DOSBox-X
A DOSBox fork that also runs Windows 3.x, 95, 98 and Me, plus Japanese PC-98 software.
Replacements
Listings that take over the same core job as DOSBox-X.
DOSBox Staging
Modern continuation of DOSBox for running DOS games and software.
DOSBox Staging uses sensible modern defaults so most DOS games run without config editing, with CRT shaders and MT-32 sound, but it does not list old Windows or PC-98 support.
86Box
A low-level emulator of vintage IBM PC-compatible hardware for running old DOS and Windows systems.
86Box emulates real vintage PC hardware at a low level for DOS and Windows systems, needing original BIOS ROMs and a fast host CPU, and stops at the Pentium era.
v86
An x86 PC emulator that runs operating systems such as Linux and Windows 9x inside a web browser.
v86 runs x86 operating systems such as Windows 9x inside a web browser with a WebAssembly JIT, requiring no install but running slower than native emulation.
Also worth comparing
These listings name DOSBox-X as their own alternative, so the relationship runs both ways.
ScummVM
Replaces the original executable of hundreds of classic adventure games so they run on hardware that did not exist yet.
DOSBox-X emulates DOS and also Windows 3.x to Me and PC-98 software, covering games outside ScummVM's engine list, but it has far more settings and config file work.
