Some games<br \/>\nthat check the BIOS for capabilities may now begin to<br \/>\nuse 16-color graphics and EGC functions.<\/li>\n<li>Added PC-98 INT 18h function to read character font.<br \/>\nThis also resolves garbled text in TH01.<\/li>\n<li>PC-98 GDC emulation now uses cursor specification<br \/>\n(line per character row) to determine whether graphics<br \/>\nare doubled vertically or not. Several PC-98 games<br \/>\nswitch between 200-line (doubled) and 400-line graphics<br \/>\nby programming the GDC directly, rather than through<br \/>\nthe BIOS.<\/li>\n<li>Added various video-related BIOS variables to the data<br \/>\nin PC-98 mode.<\/li>\n<li>GDC RESET\/SYNC debug text updated to indicate which GDC<br \/>\nis undergoing the RESET\/SYNC.<\/li>\n<li>Debugger \u00ab\u00a0LOG\u00a0\u00bb command (CPU execution logging) fixed to<br \/>\nautomatically stop logging when the BIOS begins the<br \/>\nPOST routine after system reset. The user who invoked<br \/>\n\u00ab\u00a0LOG\u00a0\u00bb probably cares more about what happened up to the<br \/>\ngame crash, fault and reset rather than normal BIOS startup.<\/li>\n<li>BIOS now properly unmasks the PC-98 cascade IRQ, which<br \/>\nallows IRQ 8-15 to function, including the mouse (IRQ13)<\/li>\n<li>Debugger interface now indicates whether 80386 paging is<br \/>\nenabled or not at any time.<\/li>\n<li>Help text updates to reflect DOSBox-X changes (Shane32)<\/li>\n<li>BIOS INT 13h emulation updated to support up to 4 hard<br \/>\ndrives (Shane32)<\/li>\n<li>IMGMOUNT and BOOT code cleanup (Shane32)<\/li>\n<li>IMGMOUNT RAM drive support: Additional fixes and geometry<br \/>\nwork done, and some hangs resolved (Shane32)<\/li>\n<li>CPU emulation fixed to allow setting a breakpoint on<br \/>\nANY interrupt of a specific number, not just software<br \/>\ninterrupts. It is now possible to use BPINT to break<br \/>\nupon hardware (IRQ) interrupts.<\/li>\n<li>DOS kernel fixed to drop to the debugger if the MCB<br \/>\n(memory control block) chain is corrupted, so that<br \/>\nthe corrupted state can be examined. When the debugger<br \/>\ncontinues execution, a full restart of the DOS kernel<br \/>\nis run. If DOSBox-X was compiled without the debugger,<br \/>\nthen the normal E_Exit() path is still taken.<\/li>\n<li>Added debugger command to show, and modify, the state<br \/>\nof the PIC (interrupt controller).<\/li>\n<li>Added debugger command to view or change the A20 gate.<\/li>\n<li>Added debugger command to view the state of EMS, memory<br \/>\nhandles, allocation, and EMS page frame mapping.<\/li>\n<li>Added debugger command to view the state of XMS, memory<br \/>\nhandles, and allocation.<\/li>\n<li>Added debugger command to view the layout of the ROM<br \/>\nBIOS region (0xF0000-0xFFFFF) chosen by emulation.<\/li>\n<li>DOS kernel now logs kernel allocations, which can be<br \/>\nseen in the debugger using the \u00ab\u00a0DOS KERN\u00a0\u00bb command.<\/li>\n<li>Added \u00ab\u00a0RUN\u00a0\u00bb command as an alternative to hitting F5.<\/li>\n<li>Added \u00ab\u00a0RUNWATCH\u00a0\u00bb to the debugger, so that watching the<br \/>\nsystem run in the debugger is possible.<\/li>\n<li>Debugger data window can now be used to view memory in<br \/>\nsegmented, virtual (through paging), and physical (bus<br \/>\naddress) modes.<\/li>\n<li>Debugger window data and code view windows now indicate<br \/>\nregions of memory that are beyond the end of the segment.<\/li>\n<li>Debugger window data and code view windows now indicate<br \/>\nregions of memory that are paged out (will cause a page<br \/>\nfault if accessed)<\/li>\n<li>PC-98 A20 gate I\/O port F6h fixed to work properly as an<br \/>\nenable or disable, rather than just an enable. The PC-98<br \/>\nversion of HIMEM.SYS no longer complains about not being<br \/>\nable to control the A20 gate.<\/li>\n<li>IMGMOUNT RAM drive support: Ramdrive bug fixes and changed<br \/>\ndrive limits from ATA limits to BIOS\/MBR (Shane32)<\/li>\n<li>INT 21h fixed to use BIOS INT 1Ch to read date and time in<br \/>\nPC-98 mode. Arrowgun now runs properly.<\/li>\n<li>Fixed EMS emulation not to claim XMS memory (and zero BIOS<br \/>\nextended memory size) if EMS emulation is in EMS board mode<br \/>\n(and therefore not allocating extended memory through HIMEM.SYS).<\/li>\n<li>PC-98 INT 1Fh extended memory copy implemented. DOS games in<br \/>\nPC-98 mode can now use this API to access extended memory.<\/li>\n<li>Fixed HIMEM.SYS emulation in PC-98 mode to zero BIOS extended<br \/>\nmemory values when claiming extended memory.<\/li>\n<li>PC-98 mode now sets BIOS data area values correctly regarding<br \/>\nconventional and extended memory.<\/li>\n<li>Added rudimentary emulation of non-volatile RAM at the<br \/>\ntrailing edge of text RAM (A3FE0-A3FFF).<\/li>\n<li>PC-98 mode now adds additional BIOS data values at boot time<br \/>\nso that guest OSes like PC-98 MS-DOS can see the floppy drive,<br \/>\nsee keyboard input, and determine the boot drive properly.<br \/>\nIt is now possible to boot MS-DOS in PC-98 mode.<\/li>\n<li>Added rudimentary PC-98 INT 1Bh BIOS interrupt, at least for<br \/>\nfloppy disk emulation.<\/li>\n<li>Cleanup and formatting enhancements to IMGMOUNT ramdisk (Shane32)<\/li>\n<li>DOS CON emulation in PC-98 mode now emulates two additional<br \/>\nANSI escapes to clear the screen that are specific to NEC&rsquo;s<br \/>\nMS-DOS implementation, which fixes text layer problems with<br \/>\nRusty.<\/li>\n<li>PC-98 GDC dip switch 2-8 emulation fixed. It was backwards.<br \/>\nThis may break existing dosbox.conf configurations, apologies<br \/>\nin advance.<\/li>\n<li>Added -xms option to LOADFIX command. When given, the command<br \/>\nconsumes extended memory instead of conventional memory.<\/li>\n<li>HIMEM.SYS emulation fixed to behave more like Microsoft&rsquo;s<br \/>\nHIMEM.SYS implementation regarding global &amp; local A20 gate<br \/>\ncontrol.<\/li>\n<li>Mac OS X builds fixed to work from the user&rsquo;s home directory<br \/>\nif run from the Finder, instead of trying to operate at the<br \/>\nroot of the filesystem as directed by the Finder.<\/li>\n<li>Mac OS X builds now put the FREECG98.BMP file inside of the<br \/>\n.app bundle, and fall back to it if not found in the current<br \/>\ndirectory.<\/li>\n<li>RPM builds now install FREECG98.BMP in \/usr\/share\/dosbox-x<br \/>\nand refer to it if not in your local directory, in order to<br \/>\nbetter provide PC-98 emulation.<\/li>\n<li>PC-98 BOOT command: Loading addresses and CPU register layout<br \/>\nupdated to match actual hardware behavior, in which the boot<br \/>\nsector is loaded at just under 128KB.<\/li>\n<li>Build updates to support compiling for Windows with MinGW.<\/li>\n<li>BOOT now accepts a &#8211;debug switch that causes DOSBox-X to break into<br \/>\nthe debugger when the boot sector begins to execute.<\/li>\n<li>BOOT now accepts a &#8211;force switch to override the PC-98 lockout,<br \/>\nif the user wants to better understand why I locked it out in PC-98 mode.<\/li>\n<li>PC-98 support now supports reading font from FONT.ROM, if available.<\/li>\n<li>Code, data, and output now respond to arrow, page up\/down and<br \/>\nhome\/end keys as a user would normally expect.<\/li>\n<li>Arrow and page up\/down keyboard input now goes to active window<br \/>\ninstead of mapping directly to any specific window.<\/li>\n<li>Debugger interface now has the concept of an \u00ab\u00a0active\u00a0\u00bb window, and<br \/>\nthe title bar of each window hilights if it is active.<\/li>\n<li>Debugger interface now hides the \u00ab\u00a0variables\u00a0\u00bb window by default.<\/li>\n<li>Fixed window \u00ab\u00a0titles\u00a0\u00bb in debugger interface to fill the terminal<br \/>\nline they&rsquo;re on and use ncurses horizontal line character which<br \/>\non modern systems looks better than hyphens.<\/li>\n<li>Removed one line padding around data window in debugger interface.<\/li>\n<li>Debugger interface redesigned to permit more flexible layout<\/li>\n<li>Debugger interface no longer crashes when terminal window is sized<br \/>\ndown too small (when there is no room for the output window)<\/li>\n<li>EMM386 (ems) emulation fixed to always turn on the A20 gate when<br \/>\nthe DOS application requests to map pages into the EMS page frame.<br \/>\nThis fixes crashes with Creative&rsquo;s Sound Blaster 16 installer when<br \/>\nrun with the A20 gate turned off.<\/li>\n<\/ul>\n<\/div>\n<p><\/em><\/p>\n<p>&nbsp;<\/p>\n<p><p class=\"p_telecharger_icone_zip\"><a class=\"telecharger_icone_zip\" href=\"https:\/\/www.emu-france.com\/?wpfb_dl=7552\" title=\"Download DOSBox-X (Hx DOS)\">T\u00e9l\u00e9charger DOSBox-X (Hx DOS) v2026.07.02 (9.6 Mo)<\/a><\/p><p class=\"p_telecharger_icone_zip\"><a class=\"telecharger_icone_zip\" href=\"https:\/\/www.emu-france.com\/?wpfb_dl=7522\" title=\"Download DOSBox-X (MinGW)\">T\u00e9l\u00e9charger DOSBox-X (MinGW) v2026.07.02 (23.9 Mo)<\/a><\/p><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) v2026.07.02 (28.6 Mo)<\/a><\/p><\/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=55183\" 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.
