Author's Comment:

  • I.S. Plate emulation.
  • Fixed history state not being toggled on coprocessors when toggling master CPU history state.

Now, about the I.S. Plate....

First of all, this thing deserves an award for the most confused naming. Just in the first two pages of the device's own manual it is called the I.S. 1050 Plate, the 1050 ISP Disk Drive, the 1050 ISP, the ISP Plate, the ISP PLATE, and the 1050 ISP PLATE. I gave up trying to determine the true official name and used I.S. Plate.

Regarding the emulation, the I.S. Plate's memory map is pretty simple:

  • $0000-7FFF: 1050 $0000-0FFF mirrored 8x
  • $8000-9FFF: 8K RAM
  • $C000-DFFF: 8K RAM
  • $E000-FFFF: 4K ROM mirrored

I have no idea why the second 8K of RAM was put at $C000 instead of $A000, since it would have only needed moving a trace over by one pin on the decoder.

Accurate sector timing is forced on for I.S. Plate emulated drives. The reason is a bug in the firmware that took me a bit to work out. The firmware blindly scans for sectors during density detection for a quarter of a second and puts the sector numbers into an array without any checks. If it sees more than about 100 sectors within 0.25s the firmware overwrites its stack and crashes, due to the 1050 having pages 0 and 1 mirrored. Fortunately the firmware also has track buffering, so the read speed is generally still good. Write buffering is also supported but not enabled by default; disk copies will go pretty slowly if this is not manually enabled.

bugs fixed

  • UI: Save states and SAP files now load correctly when dragged from .zip files.

Author's Comment:

  • Improved PRIOR handling in save states. The GTIA renderer was not restoring some internal state properly, so the P/M graphics rendering switched priority (though collisions didn't). There was a separate issue where loading a save state cross-version would cause a different problem with the same symptoms; that was unfortunately saved into the supplied save state, so the fixes won't make that save state work, though they should prevent it from happening again.
  • Fixed bug where save states and SAP images wouldn't load when dragged from .zip files in Explorer, or any other non-file load path was used.
  • Fixed bug where attempting to boot a save state image through Boot Image instead of Load State would reset the computer after loading the save state.

Altirra 3.1 Beta XVIII 22/04/2018

changes

  • nw

features added

  • Disk: Added option to revert a disk in virtual read/write mode back to last saved contents.

bugs fixed

  • Disk: DOS 1 format now uses correct VTOC signature.
  • Disk: Fixed directory update bug on DOS2/MyDOS disks when deleting the last file on the last directory sector.
  • Input: Fixed startup crash when DirectInput 8 is not available.

Author's Comment:

  • Fixed crash on startup in the ARM64 build. (QEMU is nearly unusably slow for this, btw.)
  • Fixed crash on startup when running within the Windows 10 recovery console -- DirectInput 8 support is now optional.
  • Fixed a bug when deleting files from DOS2/MyDOS disks in the disk explorer: the directory wasn't updated correctly if the file being deleted was the only entry at the beginning of the last directory sector.
  • Fixed wrong VTOC signature when formatting new disks in DOS 1 format.
  • Added commands to disk UI to convert disks to DOS 1 format and to reinterleave at 12:1.
  • Added command to disk UI to revert a modified disk in virtual R/W mode, discarding changes and re-reading the original, unmodified disk image.
  • Fixed sharp bilinear filter not updating properly when changing the artifacting setting. It is supposed to disable the horizontal sharpening when high artifacting is enabled and this wasn't happening if you switched the artifacting mode after already in sharp bilinear mode.

Author's Comment:

This is the first build that I've actually published an ARM64 build for, now that I have a physical device to test on. I won't be publishing the ARM64 build all the time, but the final release will have it. The native ARM64 build is about 30% faster than the x86 build running under emulation.

Other changes:

  • Fixes and NEON optimizations for ARM64.
  • MyIDE v1 no longer shows firmware warnings.
  • Reorganized pages in Configure System into categories to make it easier to scan.
  • Added support for non-default preset input maps and added a couple of new ones.
  • Minor perf optimization to Direct3D 11 path (fixed some redundant calls).
  • Added warning when adding a full disk emulator for the first time.

Altirra 3.1 Beta XXX 01/07/2018

changes

  • nw

features added

  • Debugger: Added extended memory bank tracking support to the history window and breakpoint systems.
  • Debugger: Add custom symbol (ya) command can now add read-only and write-only symbols.

bugs fixed

  • Disk Explorer: Creation timestamp is now preserved when dragging files in and out of an SDFS volume.
  • MMU: Fixed another Axlon/PORTB memory aliasing issue.
  • Serial: Socket handling rewritten so that hanging up while a connection is still in progress no longer hangs the emulator until the connection attempt times out.
  • VBXE: ANTIC hires pixels now always have PF2/PF3 priority except with XCOLOR=1 on FX1.26 core where enabled pixels have PF1 priority.

Author's Comment:

  • Adds some support for extended memory debugging. In 6502 mode, the CPU history now tracks which bank the PC is in, and enabling global PC in the history window shows additional info for extended memory banks. The debugger uses a new XX'YYYY syntax for extended memory addresses, e.g. $EF'4800 maps to the byte at $4800 when PORTB=$EF. This makes extended memory a bit easier to deal with than the x:addr syntax, which requires mapping the banks to a linear address space. If you have MADS symbols with the bank values in the symbols, these can also be matched to banked PC addresses. Breakpoints can also be set at PORTB extended memory addresses.
  • Fixed another issue of aliasing between PORTB and Axlon extended memory.
  • Added US Doubler firmware to autodetection list.
  • Custom symbols (debugger 'ya' command) can now be read-only and write-only.
  • Fixed VBXE handling of ANTIC hires pixel priority. Priority is now always PF2/PF3 for XCOLOR=0 and <FX1.26 core and PF1/PF2/PF3 for XCOLOR=1 with FX1.26.
  • Rewrote modem networking code to make the connection step synchronous so it won't hang the emulator until the connection timeout if interrupted.
  • Accepting incoming modem calls now also triggers phone network simulation sounds.
  • Fixed broken 65C816 high memory selector in the configuration UI.
  • Removed extra file extensions from the file filters on the Save Cartridge UI so the common file dialog auto-switches extensions; both filters had most of the cart extensions to show the files, but this was also allowing the cross-type filenames.

features added

  • Debugger: .basic_rebuildvnt now has a -t option for TurboBasic XL support.
  • Disk Explorer: Added options to relax filename checking and automatically rename conflicting filenames.
  • HLE: Program loader detects conflicts with and offers to disable internal BASIC.

bugs fixed

  • nw

Author's Comment:

  • The .basic_rebuildvnt command now has a -t switch to enable TurboBasic XL label support. This allows rebuilding the VNT for protected programs that have it wiped and use TBXL labels (which otherwise would be interpreted as Atari BASIC arrays).
  • The disk explorer now has options to relax filename rules for DOS 2 compatible volumes, and will attempt to encode the names of files that don't work with the rules when copying in new files.
  • Double-clicking on a mapper in the cartridge mapper auto-confirms.
  • XEL-CF3 with the swap button is now emulated.
  • The emulator now attempts to detect if a binary program being directly loaded overlaps enabled internal BASIC, and if so will prompt to disable it. This is detected if internal BASIC is enabled and the program has a segment loading over $A000-BFFF before the first init segment.
  • Build changes: localconfig .props work again, compiler bumped to VS2017 15.7.3.

changes

  • nw

features added

  • Display: Added option for auto-switching between NTSC and PAL artifacting modes.

bugs fixed

  • Display: Fixed bug with PAL high artifacting ignoring odd hires pixels.
  • Display: Artifacting phase and saturation are now hooked up for PAL high artifacting.

Author's Comment:

  • Fixed bug in PAL high artifacting engine that caused odd hires pixels to be ignored. This was due to an optimization accidentally being turned on too often. When the emulator detects that there is no hires in a scanline, it uses a faster routine that only samples luma at half rate and uses merged pair filter kernels. For PAL high artifacting, it was accidentally running this all the time.
  • PAL high artifacting engine no longer has artifacting hue and saturation hardcoded. You may need to reset your PAL artifacting color settings as the default is likely to be pretty blown out.
  • There are now combined NTSC/PAL artifacting modes that automatically select the appropriate variation of artifacting for the current video standard. Quick review: NTSC standard artifacting emulates color from even/odd pixel patterns, PAL standard artifacting emulates chroma averaging, and the high artifacting modes do full video signal simulation.
  • Added a button to the System page of the configuration dialog to quickly toggle between NTSC and PAL. This command already existed, but you could only get to it by adding a keyboard binding.
  • Added auto-detection for 810 revision B firmware. (Thanks Nezgar for tirelessly tracking this down!)

  • POKEY: Improved accuracy of high-pass filter.

Author's Comment:

  • Rewrote POKEY rendering back-end -- high-pass now has correct half-cycle timing so PDM works without needing to fudge the cycle offset. Hopefully shouldn't have broken much and might even be a little faster.
  • Fixed Blizzard 32K cart type to use 8K banks instead of 16K banks.
  • Fixed hang when using AST 32K cart type.
  • Rewrote cart mapper dialog. It now has a checkbox to display technical details for each cart type to assist when trying to find something vaguely similar to an unknown cart.
  • Minor compiler update from VS2017 15.7.1 to 15.7.2.

features added

  • Cartridge: Added support for .CAR types 60, 67-70 (Blizzard 32K, XEGS 64K alternate, Atrax 128K raw ordered, aDawliah 32K/64K).
  • Cartridge: Added show-all override to cartridge mapper dialog.
  • Debugger: Added several new verifier modes.

bugs fixed

  • Cartridge: Fixed XEGS banking modes in The!Cart emulation.

Author's Comment:

  • Selecting color presets now resets the color matching mode.
  • Fix XEGS/SXEGS sub-emulation in The!Cart emulation -- fixed and variable banks were swapped.
  • Add some new verifier modes: loads from absolute address 0, disk I/O reads over active display list, OS calling convention violations (calling SIOV with I=1).
  • Support for cartridge types: Blizzard 32K (60), XEGS 64K alternate (67), Atrax 128K in raw ordering (68), aDawliah 32K (69), aDawliah 64K (70).
  • There is now a checkbox on the mapper dialog to override the detection if you really need to force a mapper that is not showing up (such as if the init vectors are garbage).
  • Compiler updated from VS2017 15.4.2 to 15.7.1. (What could possibly go wrong?)
