- Sinclair ZX Spectrum Emulator V1.41 - 27/7/92 - by G.A. Lunter
-
-
- Additions to the Spectrum Emulator, starting with the first version that
- was released, version 1.20. (*) = only available to registered users.
- Names between brackets are games that first indicated the presence of
- the corresponding bug in the Z80 emulator.
-
-
- 30/7/91 Version 1.20 released
-
-
- 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
-
-
- 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.
-
-
- 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 analog 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.
-
-
- 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.
