| 2024.12.04 | Dec 5, 2024 | New Release | Arrange memory device allocation so that it is possible to allocate up to about 3900MB of memory instead of 3500MB. (joncampbell123). Fix S3 LFB PCI base alignment error if system memory pushes it to a higher address (joncampbell123). Fix EGA 640x350 4-color mode (when EGA memory size is 64KB) to display correctly. Prior to this fix, 640x350 4-color only worked properly if the INT 10h Video Parameter Table was enabled. (joncampbell123). Fix S3 VGA memory size reported through register CR36 to cap at 4MB and set the value correctly. This fixes a known issue where setting vmemsize to 8MB caused Windows 98 to report memory size as 2.5MB. (joncampbell123). Fixed a problem when VZ Editor is resident in PC-98 mode. (nanshiki). INT 10: SVGA mode 0x6A does not exist on plain VGA hardware. (joncampbell123). INT 10: Fix mode 0x6A (800x600 4-color SVGA) to use a correct dot clock so that the refresh rate is >= 60Hz instead of 37Hz, and make sure mode 0x6A is a 100% clone of VESA BIOS MODE 0x102. (joncampbell123). Fix MMX/SSE instruction decoding, correct some mistakes in MMX emulation. (joncampbell123). IMGMAKE: Add -partofs option to allow control of where the partition begins in the image (joncampbell123). IMGMAKE: Add -align option so that the FAT filesystem can be arranged for more optimal I/O on devices with larger sectors, such as modern 4096-byte/sector drives. (joncampbell123). IMGMAKE: Add -label option so that the generated FAT filesystem has the specified volume label. (joncampbell123). MDA emulation: Fix non-blink attributes 0xF0 and 0xF8 to correctly render bright green background. (joncampbell123). Fixed crash when a CD image was loaded to an "empty" drive (maron2000) Log loaded .conf file (maron2000) Supress redundant screen reports in log (maron2000) Fixed mouse capture locking by middle button (maron2000) Fixed toggling the menu option "Autolock mouse" did nothing (maron2000) Fixed build failure with libc++ 19 (DimitryAndric) Fixed ful |
| 2024.10.01 | Oct 2, 2024 | New Release | Allow the ".inst" extension for CUE sheets. (Allofich) Add SET /FIRST, a DOSBox-X extension, that takes the specified variable if it exists and moves it to the front of the environment block. (joncampbell123). SET command processing has been cleaned up and streamlined. Added /ERASE command line switch to clear the environment block (DOSBox-X extension). (joncampbell123). VESA BIOS: Add new option to adjust reported linear framebuffer address by a specific number of pixels. This is needed by "Out of Control" by Contract which for whatever reason, will always draw to the LFB base minus 128 bytes. This option makes it possible to correct the demo graphics. (joncampbell123). Gravis Ultrasound: Officially, registers 0x0-0xF, the voice control registers, are documented to have a 0x0-0xF write and 0x80-0x8F read alias. Unofficially, according to the behavior of 1997 demo "Out of Control" by Contract, all GUS registers have a N and (N+0x80) alias, or at least register 0x4C, and you can read them back from either index. Or else the demo fails to detect the GUS. So add this alias, but only if enabled in dosbox.conf. Real hardware testing is required to know if the actual GUS behaves this way and which versions. (joncampbell123). Move the INT 3 default vector to well within the initial 16 bytes of the DOS kernel, away from the List of Lists and SFT. The previous placement caused certain versions of Windows 3.2 (yes, the Chinese version) to crash on startup. (joncampbell123). When using the running program to name screenshots and such, filter out all invalid characters so that Windows users can take snapshots even if junk characters are there (joncampbell123). DOS FAT driver: If INT 13h reports disk change, adapt floppy disk geometry to new disk image according to media byte. This allows DS_BLISS to present it's 720K fake floppy even if the user initially mounted a 1.44MB floppy to drive A: (joncampbell123). INT 10 mode list: Add "pitch" |
| 0.74.3 | Jul 3, 2019 | New Release | Fixed that a very long line inside a bat file would overflow the parsing buffer. (CVE-2019-7165 by Alexandre Bartel) Added a basic permission system so that a program running inside DOSBox can't access the contents of /proc (e.g. /proc/self/mem) when / or /proc were (to be) mounted. (CVE-2019-12594 by Alexandre Bartel) Several other fixes for out of bounds access and buffer overflows. Some fixes to the OpenGL rendering. |
