Names between brackets are games that first indicated the presence of
the corresponding bug in the Z80 emulator.
3/5/93 Version 2.01 released.
- Added LaTeX and PostScript doc, by Lars K\"oller,
- Added Windows icon
- Added -xb switch (black and white VGA)
- Added remark about Czech registration to doc
- Added various other things to doc
- Fixed bug in (X-)Hercules border dithering
16/4/93 Version 2.00 released.
- Z80 now supports the Spectrum 128, including '128 sound
through PC speaker or AdLib compatible sound card,
- Dutch documentation rewritten in English,
- Much better tape support, with tape files on disk, support
of headerless files and more difficult formats, easy access
to programs using LOAD "name", multiple files in a single
tape file, automatic mirroring of loaded blocks to tape
files,
- Microdrive support, 8 microdrives with cartridge-files
holding up to 126K of data, low-level I/O compatibility,
- VGA support, fast screen update and accurate colours
including bright,
- Z80 emulation nearly perfect, including emulation of
inofficial flags and undocumented features. Timing of
individual instructions is made much more accurate on fast
computers, while maintaining maximum possible speed on slow
ones,
- Spectrum keyboard layout help-screen under ALT-F1,
(*) - Disciple/+D disk read utility can translate 48K and 128K
snapshots to .Z80 files, and screen snapshots and normal
files to .TAP files. It will now also read 5.25'' (720K
80 track double density) disks, and some bugs have been
fixed,
- Z80 now reads a .INI file at startup for default settings,
- Changing the hardware (SamRam, Spectrum 128) now possible
on-the-fly,
- The R register and LDIR emulation flags are saved in .Z80
snapshots,
(*) - The emulation speed slowdown is now accurate from 8 MHz PC's
to the fastest available 486 machines. The emulation speed
can be brought back to 7%,
(*) - Source files now include source of SamRam software,
- Support of AZERTY keyboards,
- The emulator can now run under Windows,
- Emulator can use other default 16K rom (switch -xr),
- The program uses EMS if available, for fast bank switching,
(*) - CONVERT utility can now also convert a screen to a .PCX file,
(*) - CONVZ80 now also supports the .PRG and tape files of SpecEm
(Kevin J. Phair) and tape files of ZX (Rindt and Brukner),
(*) - New utility: Z802TAP, to convert a .Z80 snapshot to a .TAP
tap file,
(*) - New utility: TAP2TAPE, to write a .TAP file back to tape,
- Fixed CGA colours bug,
- Fixed CTRL-BREAK bug,
- Fixed several other bugs, and
- a nice new intro screen.
14/8/92 Version 1.45 released.
- Z80 emulator is now about 5% faster. Arnt Gulbrandsen,
the author of JPP, pointed out to me that I was clearing
the BL register too often.
- The analogue joystick now really works
(*) - SAVEing programs to tape now really works (if you're a
registered user)
- You can now load .SNA files (commonly used snapshot format)
directly into the emulator, without having to convert them
with ConvZ80.
- The Interface-I RS232 channel can now also be attached to
COM3 and COM4.
(*) - ConvZ80 now also supports the .SP format used by a Spectrum
emulator called 'SPECTRUM', written by Pedro Gimeno.
- A capacitor in DIAGRAMS.Z80 had the wrong value (17-8-92)
- .SNA files that were loaded were not properly closed,
resulting in a FILE NOT FOUND error. (17-8-92)
27/7/92 Version 1.41 released. The 1.40 version of Z80.EXE was
packed with COMPACK (sort of PKLITE), which was bugged:
it didn't run on some '386s and '486s. This version isn't
packed anymore.
16/7/92 Version 1.40 released, Shareware and for registered
users.
(*) - Full tape support! A program DIAGRAMS.Z80 is supplied,
that consists of two diagrams of tape-adapters for PC's,
and a test-program useful for calibration of the
adapters.
(*) - A utility to read DISCiPLE floppies.
- The analogue IBM joystick and a special interface for
digital (Spectrum) joysticks are supported. In the
documentationfile is a diagram for the digital joystick
interface.
- A more extensive manual, and a summary for English-
speaking users.
- Speed measurement of the Z80 emulator is more accurate.
(V1.20 overestimated the speed.)
- Functionkeys F1-F7 and F10 are now used.
- The Emulator can run in 'Real'-mode, for better sound
and for tape (speed-)load and save.
- R register emulation is now perfect, so that protected
games (e.g. lenslock games) can be loaded.
- Video routines are faster.
- Several bugfixes concerning writes in ROM. (Strong Man)
- The settings of Issue 2 emulation, Double Interrupt
frequency, Video synchronisation mode and joystick are
stored in .Z80 files.
6/11/91 Version 1.30, for registered users only:
- It is now much easier to choose a file from the main
menu: the cursor keys, PgUp and PgDn can be used to
browse through the list of files, and letter-keys make
the bar jump to the first file that starts with that
letter. The files are now alphabetically ordened.
- Sinclair joystick 1 added (keys 1-5)
- If a path is entered at the command line, the Emulator
automatically jumps to the main menu, option 'load
program', and changes to the specified directory.
- If a file is attached to the RS232 in- or output
channel, the read- or write-position is shown (main
menu, options I and O)
- Switches -yl and -yh are added, for Low and High video
synchronisation. With these switches, the flickering of
sprites of some games can be reduced. (Ghost 'n Goblins,
Uridium)
- Bugfix: DOS-clock ran too fast in version 1.25
- Bugfix: On AT's the Emulator crashed if Spectrum programs
used interrupt mode 2 while the I register was 255.
(Full Throttle)
- Inofficial flags are now emulated better. (Ghost'n Goblins)
(*) - Extra utility CONVZ80, converts .Z80 files in .SP and
.SNA files, the snapshot formats of the Spanish Spectrum
emulator VGASPEC and the Norwegian Spectrum emulator JPP
respectively, and vice versa.
(*) - Utility Z80DUMP; displays the header of .Z80 files.
4/10/91 Version 1.25, for registered users only:
- Bugfix of instructions CB30 to CB37 (Bounder)
- 50 Hz interrupt and video update run 180 degrees out of
phase (BC Quest for Tires)
- SLA, SRA, SRL sped up.
(*) - Switch -z added: the Emulator now can be slowed down to
about a factor 4.
- Bugfix sound: some computers only produced sound after a
OUT 31,13.
- Switch -2 added for Issue-2 emulation (Spinads)
- Bugfix GETRS: now reading from COM2 works, and an
on-screen counter shows the progress.
(*) - CONVERT extended: GIF-files can be made directly from
.Z80 files
30/7/91 Version 1.20 released. Eerste, geheel Nederlandse versie.
(First, entirely Dutch version.)
