What's new in version 7.00

New display options
User-selectable resolutions for full screen mode. Asus Eeepc users can
now use 800 x 480 to avoid having to scroll.
LCD friendly refresh rates. CRT users can still use 100Hz for a more
authentic display.
Support for widescreen (16:9) display modes. Spectaculator will
maintain the correct aspect ratio when using these modes.
Support for 16 bit (high colour) full screen display modes.
Significantly improved performance on Windows Vista in full screen
mode.
Fixed initial flicker when Spectaculator first loads and the user's
display settings are applied.
On-screen virtual keyboard
Spectaculator now has an on-screen virtual keyboard.
The layout can be switched between the original rubber-keyed Spectrum
and the Spectrum +/128K
All keys are clickable.
MGT/Datel Plus D emulation
Emulates standard G+DOS and Uni-DOS variants.
Supports two virtual disk drives.
Reads, writes and formats standard .mgt and .img disk image files.
Support for extended .mgt and .img files which have 81 tracks, e.g.
AlchNews 20.
Reads, writes and formats real Plus D / DISCiPLE 3½" disks (Windows
2000 and Windows XP only).
Disk drive sound effects.
Disk drives window for easy management of disk images. Disk images can
be write protected, formatted, ejected, inserted and written to real
floppy disks.
Capture the Plus D's printer port output to a file, the Windows
clipboard or any serial or parallel port attached to your PC.

Emulation of the snapshot button to write snapshots to disk images or
real floppy disks.
Added new blocks to the zx-state (.szx) format to support state
loading and saving.
Support for loading and saving .z80 snapshots with Plus D information.
Unfortunately the .z80 format knows nothing about the contents of the
Plus D's RAM, the number of drives attached, state of the printer
port, type of ROM installed etc. Use zx-state (.szx) instead.
Disk Wizard (Windows 2000/XP only)

Backs up Plus D formatted floppy disks (including Uni-DOS) to .img
and .mgt disk image files.
Writes .img and .mgt Plus D disk images back to real floppy disks
(including Uni-DOS disks which have a mangled Head ID field in the
sector headers).
New Action Replay (RZX) features and fixes
Added support for rollback with multiple bookmarks.
Disabled the debugger when in tournament mode.
Spectrum +2A/+3 emulation

Improved emulation of these models thanks to information gained from
running Kio's hardware test program on real hardware. Thanks Kio!
Fixed crash when inserting a blank, double-sided disk image into any
+3 drive.
Spectrum 48k/128k/+2 emulation
Implemented contention on refresh cycles when the I register is
pointing to ULA address space. (Thanks Woody and Philip Kendall).
Added memory and I/O contention to upper RAM area on the Spectrum 128k/
+2. (Thanks Patrik Rak and Philip Kendall).

A read of port $7ffd on the Spectrum 128k/+2 now correctly writes the
floating bus value back to that port. (Thanks Fredrick Meunier and
Marat Fayzullin).
Pentagon 128 emulation
Fixed floating bus values being returned for all unattached ports, not
just $ff. (Thanks Philip Kendall).
Enhancements to the Z80 core
Added the rest of the more esoteric undocumented instructions.

Fixed a bug that could possibly crash the emulator.
Added a fast instruction fetch monitoring system for hardware that
needs it (e.g. µSpeech, Interface 1, Plus D).
Fixed IM 0 interrupt acknowledge timing.
Fixed INTREQ timing for all UK models after running Woody's test
program on real hardware. (Thanks Woody).
Fixed undocumented flags in BIT n,(IX+nn) instruction.
Maskable and non-maskable interrupts are now not accepted during $dd/
$fd sequences.
Spectrum 128/+2/+2A/+3 communications ports
The Spectrum 128/+2/+2A/+3 communications ports output can now be
redirected to a file, the Windows clipboard or any parallel or serial
port attached to your computer.

Fixed deadlock when redirecting output to LPT1 when there was nothing
physically connected to it.
Favourites list
Broken links can now be fixed.
The favourites list is not lost when running multiple copies of
Spectaculator at the same time. You will receive a warning if you try
to change the list using two or more concurrently running copies.
Audio cassette files
Support for v1.20 of the TZX Format (Set Signal Level and Generalized
Data Blocks).
Fixed the off-by-one-byte bug in skipping unknown blocks in ZX Tape
(.tzx) files.
Added support for CSW version 2 files that are not Zlib compressed.
Currah µSpeech
Re-wrote the emulation to use memory mapped I/O ports rather than ROM
traps.
Fixed the speech when in Sinclair BASIC (this was broken in 6.25).
Extracted the allophones from a real µSpeech for a more genuine
sound.
Fixed intonation (broken since 5.0)
ZX Interface 1
Removed the ROM traps as they are no longer needed. As a side-effect,
games and other programs which do a crude CRC on the 48K ROM (e.g.
Fairlight) now load with the Interface 1 connected. Dr. Logan's
diagnostic test program now works correctly.
Fixed the Eject Microdrive Cartridge keyboard short cut (Alt+J) when
using Ctrl as Symbol Shift.
Spectaculator can now use .mdr files that have the write-protect byte
missing from the file.
ZX Interface 2
Spectaculator can now load 8KB ROMs such as the Parker prototypes. The
second 8KB block in the ROM space is a duplicate of the first 8KB.
New joystick options
Added emulation of the Comcom programmable joystick interface. This
joystick allows mapping of the directional controls as well as the
fire buttons to keys on the Spectrum keyboard. You can map all 32
buttons on your real joystick/gamepad, if you have that many.
Removed the Always return valid Kempston joystick data option. This
only existed for compatibility with some old .sna snapshots that
assumed a Kempston joystick would always be present.
Changed the port decoding for Kempston mode to default to $df since
that's what nearly all the various Kempston clones that were made
respond to. This gets the Kempston option on various games such as
Nonamed and Jungle Warrior working. You can change the decoding back
to Genuine Kempston ($1f) in the Advanced tab of the Options property
sheet.
The joystick configuration dialog has been redesigned so it is now
possible to completely disable joystick emulation, even when you have
a real joystick attached.
Debugger fixes
Displays (IX/IY-128) correctly.
Correctly decodes redundant $dd and $fd prefixes.
Fixed display when memory is paged during single-stepping.
Changed SL1 opcode to SLL as this mnemonic is more common, if
incorrect.
The decimal/hex setting is now respected by the register(s) editor.
Cassette Recorder
Fixed incorrect triggering of auto stop when loading the following TZX
files:
Sailing
Lode Runner
Vega Solaris
Fixed auto play not working with Striker.
Multiface
Several users reported random crashes in TR-DOS when emulating the
Pentagon 128 and Scorpion ZS 256. This is due to the Multiface being
enabled when it is not compatible with the Beta 128 disk hardware. The
Multiface is now disabled when emulating these machines.
The Multiface emulation has now been completely re-written. The
Disable switch on the Tools->Multiface menu now only works for the
Multiface 1 (since it was the only model which had a physical disable
switch).
Triggering an NMI (Control menu->Generate NMI) when the Multiface 128
or Multiface 3 is disabled (they are both disabled at power-on) will
now correctly just generate the NMI and not activate and page in the
Multiface.
The Multiface red button (Tools menu->Multiface->Activate) is required
to activate and page in the Multiface 128 and Multiface 3
Saved Multiface 3 snapshots will now reload.
The contents of the ROM are now saved to zx-state (.szx) snapshots if
Enable writes to Multiface ROM is selected.
Miscellaneous
Spectaculator's plug-ins are no longer UPX packed since a few
incompatibilities have been found which can cause crashes.
Tidied up the menus, adding access keys (mnemonics) where they were
missing.
Startup error dialog boxes no longer appear behind the splash screen.
View->Border->Small now correctly sets the correct window size when
the menu bar wraps.
Copying the screen image to the clipboard now works in fullscreen
modes.
Saving the screen image now works if Spectaculator is in fullscreen
mode.
The Quick load dialog box now lists the snapshots in the same order as
described in the online help (newest at the top).
Imported machine code can now be immediately executed.
The File->New dialog box can now be navigated correctly with the
keyboard.
Double-clicking the title bar now enters full screen mode, just like
the maximise button.
Fixed ZX Printer listings having lines cut-off at the bottom of a
page.
Tape sound is now recorded when using the audio recording.
ZS Scorpion .z80 snapshots are now saved with the correct page
numbers.
