DOSBox-X Git (2025/12/27) is the latest version of a DOSBox branch that emulates an Intel x86 PC, enabling the run of old MS-DOS games on modern operating systems like Windows and Linux. Recent updates address OpenGL crashes caused by buffer allocation issues, introducing an additional 4K buffer to prevent segfaults. The update also includes optimizations for scaling and code cleanup. This emulation software is essential for enjoying classic games that aren’t compatible with contemporary hardware and software environments. Download the latest version and check out the changelog for more details.
DOSBox-X Git (2025/12/27) has been compiled. DOSBox-x is a variant of DOSBox. DOSBox emulates an Intel x86 PC, providing sound, graphics, mouse, joystick, modem, and more, which are essential for playing many classic MS-DOS games that cannot be executed on contemporary PCs and operating systems like Microsoft Windows XP, Windows Vista, Linux, and FreeBSD.
DOSBox-X Changelog:
* Oh. It turns out OpenGL crashes occur because the modified lines exceed the draw height for unknown reasons, and libgallium does not perform range checks. We will implement our own checks instead.
* Resolve OpenGL libgallium crash during mode change. Rather than exactly allocating the buffer size needed for the texture, allocate an extra 4K. Modern MesaGL/libgallium employs SSE/AVX instructions for memcpy, which can inadvertently read slightly beyond the buffer’s end, leading to a segfault in Linux.
* One line follows another, so why multiply? This could provide a minor optimization for simple scalers.
* more
* Retab, cleanup
