The delay by default will slow disk I\/O down<br \/>\nto mid 1990&rsquo;s IDE PIO speeds, which can resolve issues<br \/>\nwith MS-DOS demoscene or game executables that can<br \/>\nmalfunction when disk I\/O is too fast.<\/li>\n<li>PIC code updated to enforce a proper IRQ delay on ALL<br \/>\nIRQ signals, which fixes issues with MS-DOS executables<br \/>\nthat have race conditions between their code and their<br \/>\ninterrupt handlers.<\/li>\n<li>DOS Shell now shows the full intro text only at first<br \/>\nrun, instead of every shell invocation.<\/li>\n<li>Use FCB record size of 128 bytes if the FCB record size<br \/>\nis zero (from DOSBox SVN).<\/li>\n<li>PC speaker fix not to generate a continuous tone if<br \/>\nthe PIT timer was set to mode 0. This fixes issues with<br \/>\nmany early 1990s demoscene executables leaving the PC<br \/>\nspeaker enabled (BEEEEEEP).<\/li>\n<li>Register DEBUGBOX.COM at DOS environment start instead<br \/>\nof boot, which allows the command to work again.<\/li>\n<li>EXE loader sets stack pointer (SS:SP) into PSP segment<br \/>\n(from DOSBox SVN)<\/li>\n<li>EXE loader fixed to use the larger of the minimum and<br \/>\nmaximum memory sizes listed in the EXE header, which<br \/>\nfixes some demoscene executables with a minimum size<br \/>\nlarger than maximum.<\/li>\n<li>VGA DAC (palette) emulation updated to better match<br \/>\nactual SVGA chipset (Paradise SVGA) behavior, which<br \/>\nfixes some VGA palette errors in some demoscene<br \/>\nproductions.<\/li>\n<li>Added -nocachedir option to internal MOUNT command, to<br \/>\ndisable directory caching for a local folder mounted<br \/>\nto a drive letter. When mounted this way, changes on<br \/>\nthe host filesystem are immediately visible in the<br \/>\nguest DOS environment.<\/li>\n<li>Added -ro and -rw options to internal MOUNT command, to<br \/>\nallow mounting local folders to a drive letter as a<br \/>\nread-only volume.<\/li>\n<li>MIDI Fluidsynth fixed to initialize and free state properly<br \/>\nso that switching to and from Fluidsynth doesn&rsquo;t cause<br \/>\na segfault or crash.<\/li>\n<li>MPU-401 fixed to allow changes to MIDI configuration from<br \/>\nCONFIG.COM.<\/li>\n<li>DOS filename handling fixed to maintain ASCII conversion<br \/>\nto uppercase, while not converting Shift-JIS double-byte<br \/>\ncharacters in PC-98 mode. This fixes Shift-JIS filename<br \/>\ncorruption when the trailing byte can be mistaken for<br \/>\nlowercase ASCII a to z.<\/li>\n<li>Windows fixes to keep menu bar items updated with<br \/>\nDOSBox-X state.<\/li>\n<li>Remove WM_DROPFILES handling, for now. The code remains<br \/>\nto allow re-enabling later.<\/li>\n<li>SDL 1.x builds fixed to process only WM_COMMAND (menu<br \/>\nbar) and WM_SYSCOMMAND (system menu) events so that<br \/>\nthe general chatter in modern Windows system does not<br \/>\ndrown out the messages. This fixes issues where the<br \/>\nmenu bar doesn&rsquo;t work on some systems.<\/li>\n<li>SDL 1.x builds fixed to handle menu bar input using<br \/>\nSDL&rsquo;s WM events instead of fighting with SDL&rsquo;s message<br \/>\npump to receive menu events. This fixes potential<br \/>\nissues with losing menu bar events.<\/li>\n<li>dosbox.conf reference included with Windows builds<br \/>\nnow uses MS-DOS line endings so that the file can be<br \/>\nedited in NOTEPAD.EXE<\/li>\n<li>New dosbox.conf option to control whether the menu is<br \/>\nshown by default in Windows builds.<\/li>\n<li>titlebar= SDL dosbox.conf option, to allow showing a more<br \/>\nuser friendly name for the program instead of just using<br \/>\nthe EXE name.<\/li>\n<li>E_Exit() on Windows now displays the message using<br \/>\nMessageBox() in addition to sending to STDERR, so that<br \/>\nWindows users see the error even if they are running<br \/>\nit from the desktop instead of the command line.<\/li>\n<li>PC-98 EGC bit shifter emulation fixed to correctly support<br \/>\nascending and descending bit shifting in either direction.<br \/>\nThis fixes screen shake emulation errors with Touhou Project<br \/>\nTH04 and TH05.<\/li>\n<li>Linux\/X11 fixes to SDL 1.x to better match and compare<br \/>\nVisuals (descriptions of the screen) since X11 libraries<br \/>\ndon&rsquo;t seem to use the same pointer values for the same<br \/>\nVisuals.<\/li>\n<li>ALT+TAB or loss of focus from fullscreen in Windows now<br \/>\nrestores the window instead of minimizing it.<\/li>\n<li>3Dfx OpenGL will hide the minimize and maximize buttons<br \/>\nin Windows while active.<\/li>\n<li>Windows menu bar items are now grayed out when 3Dfx OpenGL<br \/>\nemulation is active (items that cannot be used at that time).<\/li>\n<li>Fix Windows system menu to always keep \u00ab\u00a0show menu\u00a0\u00bb.<\/li>\n<li>GFX rendering fixed not to render any output while 3Dfx<br \/>\nOpenGL emulation is active.<\/li>\n<li>3Dfx OpenGL bug fixes to properly restore the DOS console<br \/>\nwhen the 3Dfx card is de-initialized and the game returns<br \/>\nto the DOS prompt.<\/li>\n<li>Linux\/X11 window output fixed to keep the window on the<br \/>\nscreen even when switching between OpenGL and non-OpenGL,<br \/>\nand when setting the SDL video mode.<\/li>\n<li>Remove some init hacks and SDL forced reinitialized hacks,<br \/>\nso that the window is stable on the screen.<\/li>\n<li>Added code to do more OpenGL state initialization (both<br \/>\noutput=opengl and when initializing 3Dfx OpenGL emulation)<br \/>\nto make more consistent output.<\/li>\n<li>3Dfx voodoo OpenGL based emulation fixed to switch out of<br \/>\nfullscreen mode IF DOSBox-X was fullscreen at the time the<br \/>\ncard is initialized.<\/li>\n<li>3Dfx voodoo OpenGL based emulation no longer allows fullscreen<br \/>\nmode, and does everything it can to prevent window resizing.<\/li>\n<li>Linux\/X11 disable XRandR, XV, and X modeset functions. Do not<br \/>\nchange monitor resolution.<\/li>\n<li>MPU-401 MIDI emulation fixed to look at all conductor message<br \/>\nbytes for code 0xFC (ALL END) instead of just the first byte.<br \/>\nThis fixes hangs in games that send additional bytes prior to<br \/>\n0xFC and then expect the MPU-401 to signal 0xFC back when the<br \/>\ngames are waiting for music to stop.<\/li>\n<li>Fix DOS CON driver not to signal data ready for PC-98 scan<br \/>\ncodes that have no corresponding ANSI code. Tapping numeric<br \/>\nkeypad keys during the title screen in Touhou Project should<br \/>\nno longer cause the game to pause waiting for keyboard input<br \/>\nwhen going into demo mode.<\/li>\n<li>Fix DOS CON driver to signal data ready for buffered escape<br \/>\ncode.<\/li>\n<li>Fix PC-98 keyboard emulation not to apply IBM PC \u00ab\u00a0extended\u00a0\u00bb<br \/>\nkeyboard scancode filtering.<\/li>\n<li>Window maximization does not count as a user resize preference.<\/li>\n<li>Fix Windows builds to enable DirectSerial, Direct LPT, modem,<br \/>\nemulation.<\/li>\n<li>New mapper shortcut to restore the window&rsquo;s original size.<\/li>\n<li>Fix bug with SHL instruction and OF flag, which corrects some<br \/>\ngames and their decompression routines.<\/li>\n<li>Fullscreen (monitor) modesetting removed. DOSBox-X either runs<br \/>\nin a window, or scales up to fill the monitor, but will not change<br \/>\nthe monitor resolution.<\/li>\n<li>Resize handling fixed to differentiate user resize verses resize<br \/>\ncaused by DOSBox-X changing the window dimensions.<\/li>\n<li>Linux\/X11 fixes to avoid flickering when resizing the window, and<br \/>\nto avoid redrawing unless necessary.<\/li>\n<li>Window resize management, to scale\/arrange the output to fit the<br \/>\nwindow (for output= surface, opengl, direct3d)<\/li>\n<li>Enable resizing again, except when the GUI or mapper is active.<\/li>\n<li>Fix Linux\/X11 to always take resize events, instead of ignoring<br \/>\nall further resize events just because one resize event is forever<br \/>\n\u00ab\u00a0pending\u00a0\u00bb<\/li>\n<li>Linux\/X11 builds now track the size of the window on the desktop,<br \/>\nto keep track of resizing and maximizing.<\/li>\n<\/ul>\n<p><\/em><\/p>\n<p>&nbsp;<br \/>\nLes binaires 32 et 64 bits sont d\u00e9sormais dans la m\u00eame archive.<br \/>\n&nbsp;<\/p>\n<p class=\"p_telecharger_icone_zip\"><a class=\"telecharger_icone_zip\" href=\"https:\/\/www.emu-france.com\/?wpfb_dl=7136\" title=\"Download DOSBox-X (Visual Studio)\">T\u00e9l\u00e9charger DOSBox-X (Visual Studio) v2026.05.02 (28.4 Mo)<\/a><\/p>\n<p class=\"p_site_officiel\"><a class=\"site_officiel\" href=\"http:\/\/dosbox-x.com\/\" target=\"_blank\" rel=\"noopener\">Site Officiel<\/a><\/p>\n<p class=\"p_en_savoir_plus\"><a class=\"en_savoir_plus\" href=\"https:\/\/www.emu-france.com\/emulateurs\/10-ordinateurs\/118-ibm-pc-et-compatibles\/\">En savoir plus&#8230;<\/a><\/p>\n<div class=\"fcbkbttn_buttons_block\" id=\"fcbkbttn_left\"><div class=\"fb-share-button  \" data-href=\"https:\/\/www.emu-france.com\/?p=54717\" data-type=\"button_count\" data-size=\"small\"><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Il s&rsquo;agit d&rsquo;un fork de DOSBox des plus int\u00e9ressant, destin\u00e9 \u00e0 Windows Linux et MacOS et cr\u00e9\u00e9 par Jon Campbell.
