features added

  • nw

bugs fixed

  • Input: Direct keyboard layout had incorrect mappings for Ctrl/Shift+Space.
  • Input: Ctrl/Shift are now blocked from virtual key mappings when used by input maps with the 'share' option off. (They are still processed for character mappings due to OS limitations.)

authors comment:

  • SIDE3 fixes for cartridge emulation and SDHC capacity reporting.
  • Added .side3 debugger command.
  • Fixed Ctrl/Shift+Space not being bound correctly in the direct key layout.
  • Ctrl/Shift are now blocked from keyboard processing for virtual key bindings when used in input maps, unless the 'share' option is set. Note that character (cooked) bindings are not affected, because of the way that the OS keyboard driver works and AltGr being equivalent to Ctrl+RAlt.

features added

  • Devices: Added virtual hard disk device that translates a read-only host directory to a FAT16, FAT32, or SDFS partition image.
  • Devices: Added temporary write filter hard disk device.

bugs fixed

  • Display: Fixed intensity scale color setting not affecting saturation in NTSC high artifacting mode.
    Display:
    Fixed an issue in the NTSC high artifacting chroma filter that was causing some excessive banding.

authors comment:

  • Removed support for old WDDM 1.0 drivers that only supported RGBA and not BGRA in Direct3D 10. This will only affect you if you are running old Vista drivers on Windows 7 and have D3D11 enabled (in which case you should update).
  • Fixed a bug that caused XF551 emulator to intermittently break after about 10 minutes.
  • Added two new hard disk devices: a temporary write filter, that buffers writes in-memory to a read-only device, and a virtual SDFS device. The latter provides an virtual APT partition created from loose files, like the virtual SpartaDOS disk.
  • Fixed the Intensity Scale color setting working differently with the NTSC high artifacting engine, where it was not properly scaling chroma.
  • Fixed a bug with the NTSC high artifacting chroma filter that was causing excessive banding, due to truncation of the filter response.
  • The bloom effect engine now uses sRGB textures on D3D11 to reduce banding.

The work on the display code was prompted by a new monitor that I got that supports HDR/WCG and adaptive sync. HDR on Windows 10 is, frankly, a total mess -- the way it is integrated into the system is non-sensical, with it having to be enabled system-wide to use it at all. It would have some benefit in the emulator in being able to boost brightness higher than the desktop and encode to wider gamuts like DCI-P3, but there is some really bad compression going on at scRGB >1 on my system that makes it unusable since I can't tell what the transfer curve is. I could probably fix this in full-screen mode by bypassing to the NVIDIA or AMD APIs to enable HDR and outputting HDR10 directly, but that's too much work right now.

Adaptive sync / FreeSync / G-SYNC does mostly work, but there are still some gotchas. The primary benefit is that it allows the monitor to actually run at 49.86Hz or twice that for smooth PAL video. You will need to disable Vertical Sync in the emulator for this to work. On my system, it only works through DisplayPort and not HDMI, and can sometimes fail to activate when multiple monitors are active. For D3D9 it only works in full-screen mode; in D3D11 it will work windowed and borderless fullscreen as well as long as windowed mode G-SYNC is enabled in NVIDIA settings. When enabled correctly, it largely eliminates the PAL juddering.

features added

  • Disk Explorer: Added options to import/export files with text (line ending) translation.
  • IDE: VHD differencing mode images can now be mounted.

bugs fixed

  • Disk: Generic disk emulation profile supports XF551 acceleration again.

authors comment:

  • Fixed "disk already mounted" warning dialog being cut off vertically.
  • Generic dialog now has traditional Windows message box sounds.
  • The New Disk dialog no longer resets settings as frequently now, especially when changing disk formats.
  • Disk Explorer has context menu options to import and export files with text (EOL) translation.
  • SoundBoard 2.0 addressing range and word mode fixes. U1MB no longer controls SB2.0 devices.
  • Some cleanup and consolidation of the way that the standard disk emulator handles the various profiles so the parameters are in nice tables. The default Generic profile now has XF551-style high speed enabled, which had inadvertently been disabled a long time ago.
  • "CPU history not enabled" error in history window now follows dark mode.
  • Added support for VHD differencing images, which store changed blocks from a base image. Note that the emulator currently does not have support for changing the parent path locator in the differencing image, so if you move the base image and neither the absolute or relative paths resolve then you won't be able to mount the differencing image.
  • Fixed some errors in the virtual FAT32 device that caused the last file to be corrupted at certain volume sizes, and the MBR is no longer repeated.
  • Added a virtual FAT16 device. It is currently locked to 4K clusters, so it will only work for file sets <256M.

  • Debugger: lft -u option enables logging with microsecond timestamps.
  • Debugger: "Auto-reload ROMs on cold reset" setting is now saved.
  • Devices: Added preview SoundBoard 2.0 emulation.
  • Input: Ctrl/Shift are now optionally blocked from virtual key mappings when used by input maps with the 'share' option off. (They are still processed for character mappings due to OS limitations.)
  • PerfAnalyzer: Added trace channel for SIO command state.
  • Simulator: Throttling code updated with waitable timers for better efficiency.

bugs fixed

  • UI: ARM64 emulation dialog no longer allows saving "OK" response.
  • PerfAnalyzer: Fixed timing error for bytes sent to the computer from a full disk drive emulator, which were shown starting at their actual end times.
    Disk:
    Motor off timer adjusted for 1050 timing and to not count down during disk operations.
  • Disk: Accurate sector timing mode now waits for the full length of long sectors in 1050-based emulation modes.
  • Disk: Fixed broken audio output from Indus GT disk drives.
  • Devices: Rapidus fast RAM windows no longer have priority over ROM.
  • Devices: Fixed Rapidus main RAM speed override sometimes being reverted; main RAM is now always at slow speed and extended RAM is also slow speed.
  • Debugger: Fixed crash in 65C816 mode with access breakpoints with the same page address but different bank address.
  • Audio: Changes to the default audio device are now tracked in WASAPI mode.

authors comment:

  • ARM64 emulation warning now also displays when running the x64 build on the latest Windows 10 Insider Preview, and saving the 'Yes' response to show the website is no longer allowed.
  • Fixed a display error in performance traces where SIO bytes coming from full drive emulators were shown with their ending offset at the actual start offset time.
  • Improved accuracy of NAK timing in the standard disk emulator.
  • Fixed disk timing errors in the standard disk emulator with sector reads after multi-second delays due to the motor off timer expiring during the disk read. The timer is now suspended during the read.
  • Added performance trace channel for the SIO command signal line.
  • Standard disk emulator now waits for the entirety of a long sector to be read when using a 1050-based emulation mode.
  • Fixed a crash when ejecting a disk during a specific point in a Read Sector command.
  • SIDE 3 recovery mode is now supported (powering on with the cartridge reset button pressed).
  • Improved emulation of SIDE 3 RTC to centisecond precision and to include some miscellaneous oscillator bits.
  • Changes to the default audio device in Windows are now tracked when WASAPI audio output mode is in use.
  • Detach All now properly warns when D2: or higher is dirty.
  • Fixed busted Indus GT audio output.
  • Enabled SHA256 hardware acceleration for x86/x64.
  • Fixed some confirmation dialogs that didn't nest properly with the Configure System dialog. "Auto-reload ROMs on cold reset" is now saved.
  • Preliminary SoundBoard 2.0 emulation.
  • Tweaked program icon and updated target cursors to use Vista+ alpha-blended cursors.
  • Reverted Ctrl/Shift input map conflict behavior and changed it to an option that defaults to old behavior. The new behavior made it difficult to use the computer when the default joystick map was enabled as you couldn't type any Ctrl+X characters.
  • Fixed a crash in the debugger when setting breakpoints within the same page separated by banks (e.g. $80 and $FF0081).
  • Rapidus emulator no longer overlays OS/BASIC/self-test ROM with fast RAM windows. (Cartridges are still overlaid according to the hardware design.)
  • Fixed a bug that was causing main RAM to revert to the fast bus after resets even with Rapidus enabled; it now stays on the chip bus as intended when Rapidus is active, as that memory is on the motherboard. Extended memory is now also included in this.

  • AltirraOS: Fixed minor rounding error in ATN() constant from assembler.
  • HLE: CRITIC is no longer zeroed from PBI-based SIO acceleration to fix key repeat issues with some versions of SpartaDOS X.

authors comment:

  • Compatibility fixes to 6502 source for MADS 2.1.0. The .fl command is seriously bugged in 2.1.0 and is frequently wrong by 1ulp, so I've hardcoded all FP constants in the AltirraOS math pack as hex. There was also an ATN() constant that was incorrectly encoded by the assembler even in MADS 1.9.8b5, so the AltirraOS version has been bumped to 3.30. The fallback Ultimate1MB recovery ROM now also assembles with 2.1.0.
  • Fixed a bug in the PBI-based SIO acceleration that manifested with some versions of SpartaDOS X where key repeat would stop working. This was caused by the PBI code clearing CRITIC, which interacted badly with SDX doing a DEC CRITIC afterward to balance its INC CRITIC. This then disabled stage-2 VBLANK processing.
  • SIDE 3 emulation fixes: DMA source/destination pointer and count registers are now double-buffered, implemented activity LED and LED registers, implemented r/w bit 2 in write protect register, and SpartaDOS X switch is now implemented.

changes

  • UI: Keyboard shortcuts have been reset to default to fix a bug with them being stored in the wrong place and to only store changes from default shortcuts.
  • UI: Default shortcuts for toggling audio channels have been changed from Ctrl+Alt+[1-4] to Alt+Shift+[1-4] to fix a conflict with some AltGr+key bindings in the Spanish keyboard layout.

features added

  • Devices: Added SIDE 3 emulation.
    Devices:
    Added virtual hard disk device that translates a read-only host directory to a FAT32 partition image.

bugs fixed

  • Devices: Fixed bug where debug reads from SIDE/SIDE2 flash windows could trigger side effects during sector erase operations.
  • IDE: Fixed Rev. S not supporting some Rev. D registers and being detected as Rev. C.

authors comment:

  • .dlhistory now shows per-line display list IPs for multi-line jump instructions. This will show how your display list is going haywire if you manage to accidentally vertically scroll one.
  • Fixed a bug where custom keyboard shortcuts were getting saved at the root of HKEY_CURRENT_USER instead of in Altirra's section. The default keyboard shortcuts for toggling audio channels have also been changed to avoid conflicting with key combos in the Spanish keyboard layout. As part of these two fixes, custom keyboard shortcuts have been reset. However, from now on they will only be saved as deltas from the defaults, so when new keyboard shortcuts are added they will be merged (previously you would not see them if you had customized any shortcuts).
  • Fixed bug where IDE+2 rev D/S did not expose some registers from rev. D.
  • Fixed a bug in SIDE/SIDE 2 emulation where flash read handlers were registering side effects from debugger reads. This only affected the toggle bits during flashing.
  • Initial SIDE 3 emulation support. Currently emulated: read-only SDHC, DMA, partial cartridge emulation, basic RTC. Only tested on the SIDE 3 Loader so far.
  • Added virtual FAT32 device. This takes a host path and maps all of the files into a virtual read-only FAT32 partition for anything that can take a hard disk block device in the emulator (IDE/CF/SD/SCSI). This view does not currently live update with changes and subdirectories are not supported, but long file names and Unicode filenames are supported. It seems to pass Windows 10 CHKDSK....

Regarding a couple of things mentioned above:

There isn't currently much integration between the debugger commands and the debugger UI, though I could probably put one in here. Need to look over the Watch window again, it hasn't gotten much attention (I don't really use it). A few settings in the debugger UI are saved but a lot of it isn't.

The majority of emulator settings are saved on exit from the profile or emulator, so if you start a new copy before then, it won't see the settings. This goes double if you are in portable mode (Altirra.ini), as in that case the entire virtual Registry is not saved until exit -- running two simultaneous copies in this situation is not supported, and typically all settings will be overwritten by the last instance to exit.

authors comment:

  • Fixed disassembler opcode length table for COP n instruction.
  • Added support for double-sided ATX images. Currently this only works for XF551-style double-sided images; ATR8000-style or PERCOM-style is problematic because ATX files use physical layout and there's no way to tell how it should be mapped to logical layout.
  • Fixed a bug with physical sectors not being reversed properly, causing the XF551 to format side 2 slowly.
  • 815 track materialization routine now supports sector sizes other than 256 bytes.
  • Fixed height of JVB instruction repeats when ending a vertically scrolled region.

  • Disk: Fixed hang when loading ATX images with extra data pointing to out-of-range sectors.

authors comment:

  • AltirraOS bumped to 3.29: NOCLIK is now implemented in XL/XE mode.
  • Megacart (3) 512K banking fixed to only use bit 7 for disable.
  • Fixed a crash that could occur if somehow a disk image got persisted in settings with an empty path.
  • The Wine64 on macOS bug workaround has now been enabled by default -- it activates on the x64 build whenever a bad TEB pointer is detected and the program is running under Wine.
  • Debugger: .diskreadsec command now always uses the virtual sector size, for consistency with .diskwritesec.
  • Removed an unnecessary stat call in most file open paths and fixed some cases of poorly buffered disk image I/O.
  • Fixed bug where some portions of the emulator like the Disk Explorer could not write to double-density boot sectors when formatted by a full drive emulator.
  • Fixed bug where XFD image files were always completely rewritten on the first write instead of being incrementally updated.
  • Fixed the FDC to use proper write track limits for 300 and 360 RPM disk drives. Removed a hack that had been put in to make the 1050 work, as it now properly runs the FDC in 8" mode as the real drive does.
  • Fixed an FDC issue preventing the 1050 Duplicator firmware from formatting disks (waiting too long for initial byte write).
  • ATX: Sectors are now properly sorted by ascending position when writing.
  • ATX: Fixed bug where an unmatched extra sector info chunk would cause the parser to hang.
  • ATX: Added experimental support for double density images. The specification for this is not yet finalized, so this is gated in Tools > Advanced Configuration > image.disk.atx.full_sector_support.

authors comment:

  • Fixes an issue with Rapidus emulation where an unclean CPU switch would occur from 65C816 to 6502 mode.
  • 815 emulation now supports writing and formatting. Note that attempting to format a format-protected disk (VRWSafe mode) will end up going through the entire format, as the emulator has no way to know that the 815 is trying to format the disk until it's too late to stop it (though it will block the writes).
  • Fixed an 815 bug with sector corruption across the index mark.
  • Fixed an 815 bug with the drive indicator being left on for drive 2.

bugs fixed

authors comment:

  • Fixes to effective address computations for non-history based disassemblies.
  • Initial read-only emulation for the Atari 815 disk drive.

For those who don't know, the Atari 815 is an odd duck. It has two drive mechanisms and is the only Atari 8-bit disk drive I know of that has no floppy drive controller chip. Instead, Atari opted to brute force it with a 2MHz 6507 (faster than the computer!), 4K of ROM, three 6532 RIOT chips (mislabeled as PIAs), a MC6852 Synchronous Serial Data Adapter (a.k.a. overgrown shift register), and a data separator made out of miscellaneous logic. It is also the only disk drive that cannot read a single density disk, with its hardware and firmware limited to MFM. It also cannot read enhanced density -- the hardware is capable of doing so, but we'll give the designers a pass for not supporting a format that didn't exist yet. The 815 does support code upload, and a couple of the extra commands are suspiciously similar to ones in the 810 revision E firmware, which implies a relationship between the two. No support for high-speed, sadly, even with the 4K ROM and 2MHz CPU -- and with hardware support for another 2K ROM expansion this drive could have done a lot. As the 815 has no FDC, the firmware itself reads and writes raw MFM data, including scanning for sector headers. The emulator has to synthesize a raw MFM track to support this and without the FDC doesn't know what sectors the firmware is trying to access, so currently the emulation is read-only and only shows track numbers instead of sector numbers. The hardware strips MFM clock bits on read but requires the firmware to encode to MFM and calculate CRC-16s in software. It's surprisingly capable of doing this with the 2MHz CPU and the drive formats with a 16:1 interleave, slightly faster than US Doubler standard interleave. The one sub-par thing I've found is sync -- instead of just waiting for the $4489 pattern to appear, the 815 has to use a two-step process to detect the $44 and then check the $89. This means that it will miss the sync when a pattern like $44489 shows up and makes the drive unusually dependent upon the $00 bytes before the sync. The drive also doesn't report errors the same way as an FDC, although this is hard for me to test as ATX doesn't support double density disks yet and there aren't really any copy protected double density disks anyway.
The 815 seems to be format compatible with other double density drives, including the three boot sector convention -- which is interesting, considering when this drive was made (1980-1981?). It's also the only drive to implement the mysterious Read Spin, Motor On, and Verify Sector commands documented in the Atari Operating System Manual that no other drive implements.
You'll need the 4K firmware to make this work, combining the two 2K ROM images. I've opted for a format where the A107 chip is first and the A106 chip is second, which matches the canonical order in the address space ($0800-17FF). For convenience, it is attached. All copies of the 815 firmware that I have found, including those from Bob Woolley, are the same, with A107 CRC32 32BD3CFD, A106 CRC32 C13657E0, combined CRC32 1527D542. Some dumps come with an extra 6-byte Atari executable header that must be removed.
