DOSBox-X Git (2026/08/10) is a compiled version of DOSBox-X, a branch of DOSBox that emulates an Intel x86 PC, facilitating the running of old MS-DOS games on modern systems. Key updates in the changelog include improvements to INT 13h status code handling, fixes for working directory prompts on macOS, and refinements in BIOS setup processes. Enhancements also focus on clock management by integrating real-time clock updates and optimizing time/date modification. These updates aim to improve performance and usability for users seeking to enjoy classic games on contemporary operating systems.
DOSBox-X Git (2026/08/10) is now available. DOSBox-x is a modified version of DOSBox. DOSBox simulates an Intel x86 PC, including sound, graphics, mouse, joystick, modem, etc., which are essential for playing many classic MS-DOS games that are not compatible with modern PCs and operating systems, like Microsoft Windows XP, Windows Vista, Linux, and FreeBSD.
DOSBox-X Changelog:
* Merged pull request #6459 from cimarronm/int13-return-code
* Updated CHANGELOG
* Mapped TeleDisk sector flags to INT 13h status on read
* Returned typed INT 13h status codes from disk sector I/O
* Merged pull request #6456 from maron2000/fix_workdir
* Fixed `working directory option=default` not prompting on macOS
* Addressed issue where `working directory option=default` asked for directory selection even when specified
* Merged pull request #6457 from maron2000/update_changelog
* Updated CHANGELOG
* BIOS setup: Adjusted excessive clock stopping when changing date/time components. Now limiting clock stopping with delay only when adjusting seconds
* BIOS setup: Since CMOS register B is write-only, used a variable to save and restore it. Increased start clock delay to 500ms
* BIOS setup: Enhanced clock updates
* BIOS setup: If possible, triggered clock redrawing using the RTC update interrupt instead of a fixed 500ms delay, removing the need for lasttick hacks
* BIOS setup: Implemented a global variable for storing CMOS time, allowing the editor to set time changes smoothly without disrupting display
* BIOS setup: Waited for CMOS to signal non-busy before reading/writing time
* BIOS setup: Used clock lock/unlock to read/write without intermediate values, preventing CMOS RTC ticking while modifying time/date
* BIOS setup: Utilized the CMOS lock bit to halt clock updates during read/write operations
