DOSBox-X Git Release (May 12, 2026)

DOSBox-X Git (2026/05/12) is a version of DOSBox that emulates an Intel x86 PC, making it possible to run old MS-DOS games on modern systems. Recent updates include improvements to CDROM interface allocation, eliminating the need for MSCDEX emulation during DOS shutdown, and refining El Torito floppy boot processes. Bug fixes address issues with reference counting for CD-ROM interfaces and messages related to corrupt packed files. Additional changes enhance IDE emulation and optimize code structure.

DOSBox-X Changelog:
* CDROM: Separate function for CDROM interface allocation that functions independently of MSCDEX emulation.
* Merge pull request #6282 from maron2000/fix_int13
* Merge branch ‘master’ into fix_int13
* Merge pull request #6281 from maron2000/fix_cd
* Merge branch ‘master’ into fix_cd
* CHANGELOG
* CHANGELOG
* Commented out debug messages and resolved compiler warnings regarding uninitialized variables.
* It seems safe now to remove MSCDEX during DOS shutdown, as IDE and El Torito emulation no longer access the CD-ROM drive through it. That workaround can be eliminated.
* Fixed addref/release for El Torito floppy boot
* Converted El Torito non-emulated boot to CD-ROM reference instead of via MSCDEX
* Set MCB kernel shutdown flag for El Torito boot
* Modified El Torito floppy emulation to addref the CDROM drive once instead of depending on MSCDEX emulation
* Updated IDE ATAPI emulation to minimize runtime MSCDEX dependency post-setup
* Updated IDE emulation to utilize refcount of CD-ROM interface
* Retab
* Altered CDROM interface object to adopt refcount for potential object sharing with other code
* Updated CHANGELOG
* Fixed detection of ‘Packed file is corrupt’ log message
* Updated CHANGELOG
* Resolved issue where the upper 32-bits of LBA were always cleared
