DOSBox-X v2026.01.02 is released. DOSBox-x is a branch of DOSBox. DOSBox emulates an Intel x86 PC, complete with sound, graphics, mouse, joystick, modem, etc., necessary for running many old MS-DOS games that simply cannot be run on modern PCs and operating systems, such as Microsoft Windows XP, Windows Vista, Linux and FreeBSD.

DOSBox-X Changelog:
VESA BIOS will remove 8-bit bank switching limit if the video memory
is large enough to need more than 256 banks. Memory size will always
be limited to no more than 64 banks (128 if smaller than 64KB
granularity) only if S3 emulation is active. DOSBox Integrated Graphics
machine type is exempt from bank switching limit, so, if you are running
legacy code or Demoscene stuff against it that never clears the upper
8 bits properly, it's not going to work unless you use smaller memsize
settings. (joncampbell123).
Update BOOT command to support multiple disk images with swapping (maron2000).
Render scaler system has been modified so that render and frame caches
are now dynamically allocated, instead of fixed buffers. Not only does
this reduce memory wasted by over-large buffers, it also removes
limitations on guest video mode resolution that previously capped the
video mode to 1920x1440 or lower, and the advanced scalers (HQ2X,
Advanced MAME, etc) to 800x600 or lower. (joncampbell123).
VGA output will now automatically disable doublescan mode whenever an
advanced scaler, such as the "XBRZ" or the Advanced MAME scalers, are
selected, so that the scalers can do their job properly on the low
resolution graphics mode automatically. The user no longer has to
manaully turn off doublescan mode for those scalers to work. (joncampbell123).
Added TV, Scanline, and RGB scaler variants appropriate for VGA
200-line modes with doublescan enabled (renders to 400 lines). In fact
supporting those scalers with 400-line VGA is arguably more visually
accurate than applying them to 200 lines of graphics, because it
better reflects the actual 400-line raster as it would be displayed
on a VGA monitor. (joncampbell123).
Apparently at random, VGA render will call RENDER_DrawLine too much,
causing buffer overruns at random, so, instead of directly assigning
the scaler line handler, assign a function that checks the rendered
line count and ensures that rendering stops at the correct line
count. This should fix some random crashes or corruptions, especially
on Linux with the OpenGL output which likes to allocate EXACTLY the
amount of memory required for the frame. (joncampbell123).
A patch was submitted to DOSLIB DSXMENU to incorporate non-selectable
informational lines of text. Incorporate the updated DSXMENU binaries
into DOSBox-X (joncampbell123).
Wrote IPS patching tools IPSMAKE and IPSPATCH in DOSLIB, then incorporated
them as builtin executables on drive Z: under Z:\PATCHING. You can
now use IPS patch files to "ROM hack" your MS-DOS games. (joncampbell123)
Add map13/map14 CGA/HGC like interleaved rendering support for VGA
256-color mode. There is a game engine in development that is willing to
use such oddball modes. (joncampbell123)
Added SDL2_net to source tree (maron2000)
Fixed regression of FIFA96 CD label detection (maron2000)
Log OpenGL context version (rebb)
Force SDL window regeneration when exiting fullscreen (rebb)
Fixed file handle leak prevents save state file removal (srcdabada)
