DOSBox-X Git Update (May 7, 2026)

DOSBox-X Git (2026/05/07) has been compiled. DOSBox-x is a variant of DOSBox. It emulates an Intel x86 PC, providing sound, graphics, mouse, joystick, modem, and other features required to run many classic MS-DOS games that are incompatible with modern operating systems like Microsoft Windows XP, Windows Vista, Linux, and FreeBSD.

DOSBox-X Changelog:
* CONFIG Shell: Break into command using DEBUGBOX when debugbreak flag is set
* CONFIG shell: Follow the echo flag and display the command on the screen if activated
* Support added for debugger DOS DEVS command for guest MS-DOS boothax
* Code added to MS-DOS boothax to monitor guest MS-DOS device driver chain. Fixed bug causing MCB corruption error during guest OS boot
* Introduced a debugger command DOSDEVS to enumerate device drivers
* additional features
* Added dosbox.conf option to display each device driver in the MCB chain for debugging
* Device driver loading: Ensure the first MCB block in the chain, while moving it, belongs to CONFIG.COM
* Device driver loading: For CONFIG shell, if allocation is at the MCB chain’s beginning, load the driver at the start and shift the chain forward, mimicking true MS-DOS behavior
* Moved minimum/free MCB and dummy to post-CONFIG shell startup
* In a makeshift manner to maintain stability, processed DEVICE= lines. To permit
* comment revisions
* CONFIG shell PAUSE directive
* CONFIG shell: Executed RUN
* CONFIG.SYS device parsing
* updated reference
* Added [devices] section, began parsing it similarly to CONFIG.SYS
* Refactored CONFIG -device into a function, added a method to the Program object for more direct calling instead of through Run
* further improvements
* OSFREE no longer requires config shell
* Merged remote-tracking branch ‘origin/master’ into main-osfree
* Not every DOS_Shell is the primary shell linked with shell_psp. The LS command merely executes the shell LS command from a temporary object, fixing LS command closure of CON/AUX/PRN for the parent shell
* CONFIG shell: Added support for running CONFIG shell and debugging options to access the command prompt at various CONFIG shell stages for debugging
* revised comments
* update comment formatting
* DOS_Shell shutdown: Close all process file handles on shutdown, including the standard 5 handles to CON/AUX/PRN (to ensure they remain available when redirected). These devices will stay accessible from CONFIG to the main DOS Shell due to the new neverclose boolean flag
* DOS_CloseFile(): If refcount falls to zero and neverclose is set, avoid freeing the file object and clearing the slot, ensuring CON/AUX/PRN are always accessible
* Established a neverclose flag for the 3 default handles (CON/AUX/PRN) in the SFT, ensuring these devices remain available regardless of users closing their file handles
* PSP: Corrected close file by name to utilize DOS_CloseFile() instead of modifying the SFT table directly and freeing DOS_File objects—although it didn’t free it, merely assigned NULL to the slot after marking it as closed. Also, the code assumes the PSP object is the current object.
* Initiated CONFIG shell (for preloading device drivers before the main shell). Corrected CONFIG and SHELL to free memory during shutdown
* updated and clarified comments
* Tracking callback allocation from the shell
* retab
* Separated shell initialization from shell message initialization
* retab
* Merged pull request #6261 from maron2000/fix_cd
* CD Audio: Corrected track min.mark calculations
* CD Audio: Transitioned to the next track when the current track concludes
* Replaced fragile default handle setup in shell.cpp with a more precise direct initialization and pre-setup of the SFT during DOS setup
* Commented out an unused variable
* Updated OSFREE per the latest changes
* Merged remote-tracking branch ‘origin/master’ into main-osfree
* Repeated merges from remote branches
* more updates
