DOSBox-X Git Version (March 7, 2026)

DOSBox-X Git (2026/03/07) is a version of DOSBox that emulates an Intel x86 PC, enabling the use of old MS-DOS games on modern systems. Notable updates include the OSFREE mode, which restricts file access while allowing device access, and modifications to the shell commands. This version disallows creating files and enhances the OSFREE build by preventing access to directories outside drive Z:. Several merges from the master and other branches have streamlined functionality, focusing on the essential commands for booting disk images. The update aims to ensure better compatibility and improved operation for users relying on older software.
