2026.08.31:
- Added support for mounting TeleDisk (.td0) floppy image files. (cimarronm)
- Fixed prompting of working directory option (maron2000)
- Relax sanity check of floppy image considering specially formatted disks
(maron2000) - Disk sector I/O now returns typed INT 13h status codes instead of a
catch-all error, and the INT 13h handler propagates the specific code
(seek failed, controller failure, CRC/data error, etc.) into register
AH on read/write errors rather than collapsing every failure to 0x04.
Also fixes AH being left stale on write errors and a VFD fill-sector
write that reported failure after succeeding. (cimarronm) - On non-MSC, only define MIN/MAX if not already defined (skitt)
- Fixed FreeDOS XCOPY failed to copy files when destination directory was
not specified (maron2000) - IMGMOUNT: Fixed a regression that didn't try loading IMGMAKE.IMG if no
image was specified (maron2000) - Fixed a build error when FFmpeg is upgraded to FFmpeg 9 (maron2000)
- Fixed freeze when savestate flagged file not found (rebb)
- Fixed capture and savestate directory locations (maron2000)
- Refactored the imageDisk subclasses into their own source files and headers
(VFD, D88, NFD, empty drive, INT 13h passthrough, El Torito floppy, and
MS-DOS block device), leaving the base imageDisk class and BIOS disk-list
plumbing in bios_disk. (cimarronm) - Shell init: allocate the COMMAND.COM environment block after allocating the
shell binary/PSP in both SHELL_Init() and CONFIGSHELL_Init(), so memory
layout and ownership ordering match expected MCB-chain behavior. (cimarronm) - Debugger: fixed disassembler showing 16-bit register names for byte-sized
operands. (cimarronm) - Fixed INT 13h CHS decoding for floppies, which incorrectly used the hard
disk layout (10-bit cylinder / 6-bit sector) instead of the floppy layout
(8-bit cylinder in CH / 8-bit sector in CL) on read, write, and get drive
parameters. (cimarronm) - Fixed savestates written by a Windows build failing to load on Linux
builds. The per-drive Opts struct in the DOS component held an unsigned
long, which is 4 bytes on Windows and 8 on LP64 hosts, so the saved stream
desynchronized and the load ran off the end of the component. Also fixed
POD_Load_DOS_Mscdex looping forever on an out-of-range CD drive count, and
mounted drive paths keeping their Windows path separators when a state is
restored on a non-Windows host. (ozy24) - Fixed chs_write packing the high cylinder bits into the sector field of the
synthesized MBR partition table, which corrupted the end-CHS entry for disks
with an end cylinder above 255. (cimarronm) - Floppy INT 13h sector reads/writes now honor the bytes-per-sector code from
the disk base table pointed to by INT 1Eh instead of assuming 512, allowing
guests that reprogram INT 1Eh to access non-512 media. (cimarronm) - Debugger: Resolved named variables in expressions (zlatkok)
- OpenGL: Fixed fullscreen and modeswitching positional offsets. (DieSkaarj)
- Simplified the MCB filename-stripping logic in DOS_Execute(). (cimarronm)
- Fixed FAT volume labels being displayed as 8.3 filenames. (cimarronm)
- Fixed crash of Win9x lowend build at launch due to use of AttachConsole()
function (maron2000) - Fixed a out-of-bounds array access bug in drive_virtual.cpp (maron2000)
