- If an empty CD-ROM drive is attached to IDE emulation, return "Medium Not
- Present" instead of a read error, when asked to read. (joncampbell123).
- Add "empty drive" CD-ROM image type "IMGMOUNT e: empty -t iso" as a way
- to emulate an empty CD-ROM drive with no disc in the drive. (joncampbell123).
- Add "empty drive" floppy image type "IMGMOUNT 0 empty -t floppy -fs none"
- as a way to emulate a floppy drive with no disk in the drive. (joncampbell123).
- Video debug overlay: Fix mouse integration misalignment when the video
- debug overlay is enabled while Windows is running (joncampbell123).
- Video debug overlay: Fix segfault when enabled with 15/16bpp SVGA modes.
- (joncampbell123).
- Video debug overlay: Fix bug where video debug failed to appear in SVGA
- 15/16/24/32bpp display modes because of a design where the VGA drawing
- code points directly at video RAM except when drawing the hardware cursor.
- One symptom was that the video debug info on the side failed to appear at
- all, unless running in Windows and only within the vertical range of the
- mouse cursor. (joncampbell123).
- Video debug overlay: Do not bother showing the Attribute Controller palette
- in 15/16/24/32bpp SVGA modes because it doesn't matter there and is not
- involved with how anything is displayed. (joncampbell123).
- Video debug overlay: Fix debug info text to appear for 15/16/24/32bpp SVGA
- modes. (joncampbell123).
- BOOT --bios no longer triggers a system reset VM event, but instead just
- jumps to the new BIOS image after DOS kernel shutdown. This is needed for
- hardware and resources to stay as they were when running the BIOS i.e.
- keeping any IDE devices configured within the DOS kernel intact so that the
- BIOS can find and use them. Prior to this change, all hardware was fully
- reset and unmapped prior to running the BIOS which made IDE emulation
- unusable with BIOS images. (joncampbell123).
- BOOT --bios no longer immediately loads the new BIOS into memory, but instead
- loads and stores the image to a temporary buffer. The ROM image does not
- actually get mapped in until the DOS kernel and everything else has had a
- chance to shut down fully. (joncampbell123).
- Fix BOOT --bios not to try to load PC-98 ITF firmware unless actually running
- in PC-98 mode (joncampbell123).
- Write PC-98 keyboard translation table (non-shifted) in ROM BIOS and set the
- keyboard translation table pointer in the BIOS data area for "Nut Berry".
- This Nut Berry game also assumes lookup and translation tables exist at
- specific locations in the ROM BIOS, so put those tables there. The shift
- state table in BIOS has also been added, though at the moment, the tables
- are incomplete. (joncampbell123).
- MegaZeux from the MS-DOS days had a 256-color tweakmode that worked on some
- popular SVGA chipsets of it's time though on others it does nothing but halve
- the display resolution of text mode. The basic idea is that it makes the VGA
- card latch two 4-bit outputs of the VGA text mode into one 8-bit value, thus,
- 256 colors possible. Add support for this. However I am not sure whether this
- tweakmode is supported by S3 chipsets, so it is OFF by default and you will
- need to add "enable supermegazeux tweakmode=true" to the [video] section of
- your dosbox.conf to enable it. (joncampbell123).
- Undo the "no partition offset" change. DOOM II for PC-9821 requires it to work
- else the page flipping fails and sprites and rendering flickers as you play.
- (joncampbell123).
- Allow text layer to appear in PC-98 256-color mode. Even though I was unable
- to enable it on real hardware, "Shamat, The Holy Circlet" requires having
- the text layer visible on top of 640x400 256-color mode for the introductory
- scrolling text to appear on screen. So for now, just allow it. (joncampbell123).
- The reason some PC-9821 games have been giving bad PITCH values (double the
- correct value) to the GDC in 256-color mode has been determined. They read
- port 9A0h to determine if the GDC is running at 5MHz or not. That port 9A0h
- index was not implemented and therefore gave the game the impression it was
- running at 5MHz when it was not, therefore the doubled PITCH value. This fix
- corrects the squeezed 256-color mode and allows it to appear properly.
- (joncampbell123).
- IMGMOUNT: If the file extension is HDI, assume a hard disk image even if the
- image file is small enough to qualify as a floppy disk image. There is an
- HDI image of PC-98 game "D.O. Doki Doki Disk 8" that is 2.2MB, small enough
- to be mistaken as a 2.88MB IBM PC floppy disk and therefore fail to mount
- as an HDI image, this change fixes it. (joncampbell123, maron2000).
- Emulate PEGC PC-98 linear framebuffer at both 0xF00000-0xF7FFFF (at 15MB
- memory mark) but also make it appear at top of memory below BIOS (normally
- at 0xFFF00000-0xFFF7FFFF). Some 32-bit PC-9821 CD-ROM MS-DOS games assume
- the top of memory alias and will fail to show anything on screen without
- it (unless, alternatively, the memalias setting is set to emulate 24 address
- lines like a 386SX). Now to figure out why these same games are programming
- a GDC PITCH value that's double what it should be... (joncampbell123).
- PC-98 GDC scan offset no longer pays attention to scan offset of data
- partition in 256-color mode. Required to help fix broken 256-color graphics
- for some PC-98 CD-ROM games. (joncampbell123).
- Refuse to enable ISA 15MB-16MB memory hole if memalias is set to 24 bits or
- less. Not only is it redundant to do that but it also causes the BIOS to
- immediately crash on startup. (joncampbell123).
- IDE ATAPI CD-ROM emulation: In PC-98 mode when emulating a NEC CD-ROM drive,
- also limit sector reads to one CD-ROM sector per DRQ because the MS-DOS driver
- assumes that behavior. The driver will stall and error out if it requests a
- multi-sector read and the drive does NOT limit transfers to one sector at a
- time per IDE data transfer. This is in line with my experience writing the
- DOSLIB IDE testing program and laptops from the 1990s with IDE ATAPI CD-ROM
- drives, so it's understandable. (joncampbell123).
- The reason the CD-ROM driver in PC-98 game HDI images refused to talk to our
- IDE CD-ROM emulation is... (drumroll) we didn't report ourself as an NEC
- CD-ROM drive when given the MMC INQUIRY command. Yes, really. The OAK CD-ROM
- driver in these HDI images really does care whether or the drive is an NEC
- brand drive. What a stupid reason not to talk to a CD-ROM drive. Add code to
- default to "NEC" "CD-ROM DRIVE" as the INQUIRY result if running in PC-98 mode.
- (joncampbell123).
- Add basic rudimentary support for CloneCD (*.ccd *.img) images. It might not
- work with more complex arrangements but it is enough for most CD-ROM PC-98
- games so far. (joncampbell123).
- libpng supports the pHYs PNG chunk which describes the pixel aspect ratio of
- the PNG image. libpng 1.6 has it, use it. Programs that support the information
- like FFMPEG will then display the PNG image with the correct aspect ratio.
- (joncampbell123). [https://github.com//issues/4754]
- PC-98 mode: There is a 302KHz timer behind I/O ports 5Ch/5Eh that some MS-DOS
- drivers depend on for timing, particularly a popular IDE CD-ROM device driver
- in many PC-98 game HDI images. This change allows the driver to time out after
- about 5-10 seconds instead of an infinite hang. (joncampbell123)
- Fix INT 10h to keep hardware CRTC I/O port synchronized with BIOS DATA area
- copy so that other parts of INT 10h called by SetVideoMode do not accidentally
- talk to the wrong I/O ports. This fixes corrupted INT 10 Mode F display
- (640x350 monochrome graphics mode). (joncampbell123).
- Add DOS Int21 0x5D 0x00 - remote server call
- Inspired by FeeDOS inthndlr.c
- With this change it is possible use a plain dosbox-x to install and run
- Windows for Workgroups V3.11 as an IPX server on the pcap ne2000 interface
- offering a host directory for read and persistent write access to an
- MSDOS machine running a WfW 3.11 IPX network client.
- Please don't forget mounting with -nocachedir
- (Issue #4162)(Yogi-baer)
- Fix missing keystroke SDLK_LESS on DE keyboard on Raspbian OS (Yogi-baer)
- Fix crash when loading a language file without existing menu item "ttf_extcharset" (Yogi-baer)
- Change ISA memory hole 512kb option from boolean to true/false/auto. (joncampbell123)
- Add ISA memory hole 15mb option, make it true/false/auto.
- Auto means off for IBM compatible mode and on for PC-9821 compatible mode.
- This should allow some DOS games that depend on the linear framebuffer
- to work properly even if memsize=16 or higher. (joncampbell123)
- MIDI: set minimum sysex delay when enabled (mistydemeo)
