DOSBox-X Git (2026/05/05) is a fork of DOSBox designed to emulate Intel x86 PCs, enabling the play of legacy MS-DOS games on modern systems like Windows, Linux, and FreeBSD. Recent changes include updates related to HX-DOS, loading configurations to minimize memory fragmentation, and ensuring proper ownership of program segments during execution. Bug fixes address PSP segment handling when launching new DOS programs and optimize device request structures. For more details and to download the latest version, visit the official source.

DOSBox-X Git (2026/05/05) has been compiled. DOSBox-x is a variant of DOSBox. DOSBox emulates an Intel x86 PC, including sound, graphics, mouse, joystick, modem, and more, required for executing numerous classic MS-DOS games that are incompatible with contemporary PCs and operating systems like Microsoft Windows XP, Windows Vista, Linux, and FreeBSD.
DOSBox-X Changelog:
* Merged pull request #6257 from maron2000/fix_hxdos
* HX-DOS: Acquire Windows build from the latest non-osfree tag available
* Reminder
* Config -device: print segment load range, not only base, for debugging purposes. Provide load base and boundary to the execute function for potential error verification
* Config -device load: Move the PSP segment to the end of memory before loading to facilitate loading the driver as low as possible and to minimize small blocks of free memory (reduce memory fragmentation)
* More
* CHANGELOG
* Bugfix: When initiating a new DOS program, ensure the PSP segment and the assigned environment block reflect ownership by the program, rather than indicating the parent process owns the environment block
* Utilize dos.dcp for device request struct and the PSP segment for init string
* Config -device, free environment block
