Altirra 3.90 Beta XIII 13/10/2019

features added

  • UI: Added /reset command-line switch to selectively reset settings.

bugs fixed

  • nw

Author's Comment:

  • Fixed horizontal position being slightly off when Alt+Shift+clicking in the debugger.
  • Change default overscan setting to Normal.
  • Add H.264 + MP3 recording setting to work around an apparently long-standing and unavoidable bug in the Microsoft AAC Encoder, which introduces random oink errors into the encoded stream. Strangely this bug seems to exist in all versions of Windows that have this encoder (7-10), and has also been reported in SDK samples and OBS Studio. ????
  • Update some video recording error dialogs to new style.
  • Add bluish-white phosphor setting.
  • The 'yr' and 'yw' debugger commands now take ? as the path, too.
  • Add /reset switch to allow for selective settings reset.

Author's Comment:

  • Fixes the stereo right channel visualizer, and also fixes an issue I found where some periodic cleanup wasn't occurring on the secondary POKEY which might cause issues after a long period of time.

Author's Comment:

  • POKEY accuracy fix for two-tone mode -- 1.79MHz timers now properly reflect the additional two cycle delay in their period.
  • Some internal rework of the POKEY rendering path to support more efficient sound processing, and possibly better filtering in the future to improve suppression of ultrasonics.
  • PIA motor control audio noise volume reduced to not be quite as loud.
  • Audio monitor improved. The audio monitor now reflects the slightly different frequency for two-tone mode and displays indicators for two-tone mode and asynchronous receive mode (2 and A). The way that the audio monitor samples the audio output has also been rewritten so that it can do better filtering on the output to produce the waveform. This means that it can now show some high-frequency effects that were previously either invisible or looked like noise (sawtooth, scanline-aligned PWM). This also fixes the bug that caused the audio monitor to blank out on redraws. The time base for the audio monitor is slightly different now, with vertical blank now at the front of the graph.
  • R/W disk flush errors now print an error message to the screen indicating the OS level error (typically Access Denied). Not very happy about all the various sync programs causing file locking conflicts in this regard (that's what oplocks are for), but I'll have to figure out a workaround at some point.

This fixes a couple of the reported two-tone bugs, though there is still a third one I'm pursuing:

POKEY Bug Report 2 with clock

Thanks to the new toy, I know what's going on and just need to figure out the exact rules for it (the 5-bit noise generator is being sampled with an irregular period, which now that I know the period cycle counts does match the known LFSR).

Altirra 3.90 Beta XIII 21/10/2019

features added

  • nw.

bugs fixed

  • Devices: Fixed crash on ANTIC reading from SoundBoard hardware registers.

Author's Comment:

  • Monochrome colors are now brightened when color is present, based on linear blending of the peak signals (clamped y-c and y+c).
  • Monochrome modes now work with high artifacting. Luma/chroma filters and PAL blending are disabled, so this shows the raw chroma signal instead.
  • Fixed a double-init issue in the audio code that was slowing down startup.
  • Fixed representative color table UI not updating properly in monochrome modes.
  • Fixed a crash with SoundBoard at $D600 or $D700 when either the ANTIC display list or playfield was pointed at SoundBoard's hardware registers.

The Last V8 - podejście do "radości" gry na Neptunie 156b;P

features added

  • Firmware: Added detection for more MIO firmware images and support for auto-trimming padded 16K images down to 8K.
    Video: Added PERITEL adapter and monochrome monitor emulation.

bugs fixed

  • Disk: Fixed case where drive timing could be disrupted after hitting a drive coprocessor breakpoint.
  • SCSI: Fixed BSY being asserted in selection phase even for non-existent devices.

Author's Comment:

  • Major rework of full drive emulation internals to reduce duplication. Only (intended) major change is that a fix for debugger step timing was pushed out to all drive types -- there was a case where if you hit a breakpoint on the drive coprocessor it could mess up the drive timing and thus the active transmission.
  • Fixed a case where the disk rotate commands could be improperly disabled when using full drive emulation.
  • Added support for green and amber monitor types. The PERITEL mode has been folded into a common monitor type option.
  • Added autodetection for the v1.1m and v1.1k MIO firmware images, and automatically trim off the leading 8K of padding on 16K images.
  • Fix for non-existent SCSI drives responding during selection phase, which caused MIO startup delays with no drive.
  • Fix bitrate options not being disabled properly when first opening the video recording dialog.

Altirra 3.90 Beta XI 18/09/2019

features added

  • Disk: Added full emulation for 810 Turbo and Amdek AMDC-I/II disk drives.

bugs fixed

  • Debugger: Fixed some disassembly errors in 6809 mode.
  • Disk: Fixed some 6809 coprocessor emulation bugs.
  • Disk: Corrected side 2 sector mappings for ATR8000, Percom, and XF551 full drive emulators.

Author's Comment:

  • Amdek AMDC-I/II emulation (disk only, no printer).
  • Fixed 6809 emulation bugs with 5-bit indexing, ADCB #imm, and JMP ext instructions.
  • Fixed 6809 disassembly of LDX #imm instructions and some indirect modes.
  • Disassembly window now supports function separation and peeking for 6809, 65C02, and 65C816.
  • Fixed FDC Read Address command returning incorrect track/side on side 2.
  • ATR8000 side select is now hooked up.
  • Fixed logical-to-physical sector mapping on side 2 when using full disk emulators. There are now three separate modes depending on the drive: XF551 (side 2 reversed), ATR8000/Amdek (side 2 forward), and PERCOM (side 2 reversed by off by one).
  • Indus GT write protect latch is now hooked up so disk change based density detection works, and added button combo for forcing density detection.
  • Indus GT SIO ready sensing is now supported.
  • Fixed multiple incompatible disk warnings in a row.

Altirra 3.90 Beta X 8/09/2019

features added

  • AltirraOS: Extended memory scan limit for 800 version to $D000 to support 52K expanded configurations.

bugs fixed

  • nw

Author's Comment:

  • Enables support for hardware H.264 encoders in Media Foundation and adds support for YUV conversion within the emulator to bypass the slow stock color space converter. The resampler/conversion routines have been further optimized and the pipeline is now YUV-conversion > upsampling > chroma subsampling, and a faster sample/buffer allocator has been added. Combined with hardware encoding when available, this should significantly reduce CPU usage during encoding. Use the x64 (AMD64) build for best results as the image processing routines run faster in 64-bit. On my XPS 13 potato, this gets 720p60 encoding below 40% of a CPU core.
  • Unfortunately, Media Foundation does not have built-in support for setting the color space properties on the H.264 stream. The emulator always uses BT.709 matrix coefficients when encoding WMV7/9 or H.264, which should be a bit more consistent than previously when msvproc.dll might have used BT.601 for some resolutions. H.264 is still recommended over WMV7/9, with WMV9 being particularly slow -- the profiler shows some unexpectedly poor motion prediction routines. Might be your only option if you are trying to use this on Vista, however.
  • AltirraOS has been revved to 3.22, raises the memory check limit from 48K to 52K on the 800 version.

Altirra 3.90 Beta IX 2/09/2019

features added

  • Recorder: Added options for pixel aspect ratio and frame scaling.
  • Recorder: Added support for recording to WMV and H.264 through Media Foundation on Windows 7 and later.

bugs fixed

  • Audio: Fixed stereo mixing being twice as loud as mono mixing.

Author's Comment:

Rework of video recording engine. Now supports using Media Foundation for recording video directly into Windows Media Video and Audio (WMV7/WMV9) or H.264/AAC. This requires Windows 7 or later, Windows 10 recommended due to improved H.264 encoder. The video recorder also now has options for correcting aspect ratio and targeting standard frame sizes, so you can have the emulator rescale NTSC artifacted video to square pixels and then rescale to 480p or 720p with sharp bilinear. Note that encoding to H.264 can require a lot of CPU, especially since currently the software encoding is used due to a color conversion issue with hardware encoding (very slow NV12 converter in msvproc.dll). A quad-core is recommended for 720p. There may also be Rec. 601 vs. Rec. 709 color issues, so double-check videos uploaded to YouTube, etc. before going live. I may try doing the YUV conversion in the emulator to bypass the Media Foundation YUV handling problems but this is something for another day. WMV7/9 is there as a fallback in case H.264 isn't suitable for some reason but on all systems I've tried it is slower than H.264 encoding. ZMBV is still recommended if you're planning to do post-editing on the video.

POKEY audio rendering path has also been tweaked, thanks to this new toy:

Pokey Osciloscope

Recorded some waveforms from tap points in the audio circuit and recalibrated the emulator's non-linear output path. The raw output curve is now a bit more aggressive (1-exp(-2.9*i)) and the exponential decay curves have been made shallower (tau=2.6ms, 24.7ms). Amplifier saturation is now emulated at high dynamic volume levels. Also, fixed a bug where volume would double whenever the emulator switched from mono to stereo mixing due to a device needing stereo mixing.

Regarding aspect ratio of screenshots, you should be getting the correct aspect ratio when copying or saving a screenshot with the true aspect ratio option. This includes artifacting and (non-)interlacing. It will not match your screen, however, if you have the display stretching mode overridden to Fit to Window or Square Pixels, which causes the display to use a different (inaccurate) pixel aspect ratio.

Altirra 3.90 Beta VIII 28/08/2019

features added

  • Cartridge: Added JRC 64K + RAM cartridge type.
  • Disk: A warning is now displayed when attempting to insert a disk into a drive that doesn't support it (e.g. double-density disk into an 810).
  • Display: Added option for frame blending in linear color space for better accuracy.

bugs fixed

  • Disk Explorer: Modifying a mounted disk image now forces a disk change to flush caches on emulated full drives that do track buffering.
  • VBXE: Fixed a crash when toggling shared memory option.
  • VBXE: Fixed double correction of display with gamma or color correction options enabled.

Author's Comment:

  • Major rewrite of display setup logic to fix a bunch of corner case bugs, like frame blending giving a washed out display with PAL artifacting enabled, analysis modes rendering garbage in some modes, or double color correction with VBXE. Should be better now (knock on wood).
  • Optimized 32-bit PAL artifacting code path.
  • Fixed crash when toggling VBXE shared memory option on the fly.
  • Added option to do linear color space frame blending. This gives more accurate blended colors -- alternating luma 0 and 15, for instance, is more like luma 11 on real displays than luma 7.5. (It still flickers like crazy on a C-1702, mind you, but frame blending is also to cope when PC displays can't maintain locked frame rate.)
  • Fixed an issue with the new save states sometimes not loading because a cold reset was forced on state load.
  • Added the JRC 64K + RAM cartridge type. Cart type 160 is not supported for this, has to be selected manually.
  • Cartridge modes now appear in the mapper UI if they are possibly valid for the cartridge image size. Previously, they were not showing up if there was no autodetection rule for them, so they were only available if you checked the 'show all formats even if they may not work' option.
  • The emulator will detect and warn in some cases if you have a disk mounted in a drive that can't read it, such as a medium-density disk in an 810. This is currently implemented only for full disk drive emulation.
  • The Disk Explorer now checks whether the disk image file selected is already mounted in a disk drive and suggests to mount the image in the drive instead to prevent conflicts.
  • Modifying a mounted image in the Disk Explorer now forces a disk change on that drive interface to invalidate track buffers on that drive. This prevents a Happy 1050 from returning stale data.

Altirra 3.90 Beta VII 11/08/2019

features added

  • Video: Added PERITEL adapter emulation.

bugs fixed

  • Debugger: Fixed incorrect call nesting in history window in Z80 mode.
  • Disk: Improved accuracy of RIOT interval timer.
  • Disk: Corrected FDC head load and initial DRQ timings for Write Track command.
  • Disk: Implemented FDC Write Track quirk for back-to-back CRC ($F7) tokens.

Author's Comment:

  • Fixed history panel not nesting properly in Z80 disassembly mode due to using the wrong stack pointer.
  • Fixed 810 Turbo missing drive select configuration dialog.
  • Fixed 6532 RIOT interval timer based on checks against hardware -- now implements re-enabling of prescaler on timer read and should now be cycle-exact.
  • Fixed FDC Write Track, now has proper adjusted head load timing and head load -> initial DRQ -> index wait sequence.
  • FDC Write Track with $F7 F7 F7 sequence alternates CRC and $F7 data bytes as it does on the actual chip.
  • ... Also went ahead and implemented PERITEL mode, which now has an option under Video
