Changes List

The next bugs fixed and features added since version 1.00 of this emulator during 1997/98:

debugger can't hang computer after g or p command in long execution sequence
q debugger command returns to the non-debugger mode of execution and G debugger command turns emulator in the debugger mode
button End correctly works in menus
added analog joysticks support
screen size sets to 320x207
TED algorithm slightly modified

bugs fixed in v1.12 (XI-2002)

made correct kernal $FCxx page fix
made correct loading of PRG-files with tape origin, like PACMANIA

features of v1.14

added full range of joysticks emulation options
vertical synchronization set to 50.1Hz (early it was 54.6Hz)
added possibility to use the underscore symbol in the filenames in the menus

features of v1.15

it's the last version of emulator which can run at 100% speed at P100

features of v1.16 (III-2003)

improved interrupts handling — it does possible to run Icicle Works without problems
added poor digital sound effects support (that reached by reducing delays after writing to AdLib ports and may create problems with very old cards)
it's the last version of the emulator which can run at 100% speed at P133

features of v1.17 (IV-2003)

added PC speaker sound support — this does possible to hear digital sound effects (use F5 to change sound hardware) and does impossible to run the emulator from Microsoft Windows
added O (watchpOint) command to the debugger
added speed regulation to the menus
completely rewritten synchronization codes (now it based on the timer 37.3KHz interrupt)
added support for mouse buttons to the emulator
fixed some minor bugs

features of v1.18 (V-2003)

first version for free assembler (FASM) under GNU GPL
fixed some bugs

features of v1.19 (VII-2003)

better hardware interrupts handling algorithm (old one could cause crash of menus subsystem and hanging of computer with DR-DOS, Free-DOS, and PTS-DOS, but worked good on Microsoft MS-DOS!)
better synchronization code
renamed KERNEL.ROM to KERNAL.ROM
fixed several bugs in the debugger
added some little improvements to the TED subroutine (that cause better look of the games Squirm, Jailbreak, ...)
menus: added DELETE command (it can't remove read-only files) and one navigation bug fixed
it's first named version of the emulator (`Navsegda?' in Russian)
slightly improved PC speaker sound code
better drive letters handling
CD-ROMs support added
improved LED (lock keys indicators) handling

features of v1.20 (VII-2003)

joysticks and sound states saved now in C2F

features of v1.21 (VIII-2003)

fixed some bugs, added some minor improvements
added tape utilities CTF2WAV, CTF2TAP, and WAV2CTF

features of v1.22 (IX-2003)

fixed some bugs, added some minor improvements

features of v1.23 (XI-2003)

fixed BRK instruction, BASIC 7.0 cartridge is now supported

features of v1.24 (II-2004)

added hardware reset function
fixed some bugs

features of v1.25 (VI-2004)

added nearly exact timing. Three write only cycles for CPU during DMA are still not emulated
fixed some bugs

features of v1.26 (VII-2004)

added several minor improvements
fixed some bugs

features of v1.27 (VIII-2004)

fixed bug which caused impossibility to load read-only files from menu — this did files from boot diskette (cbm264c) unloadable

features of v1.28 (X-2004)

added poor disk drive (device #8 only) support by interception of $FFD5 calls. It becomes possible to use LOAD and DLOAD. This makes more than 1/3 of D64-images usable
the file deletion is intercepted by "Are you sure?" question now
fixed some minor bugs

features of v1.29 (XII-2004)

slightly improved disk drive support (this makes more than 40% of D64-images usable)
added some minor improvements

v1.31 (VIII-2005)

added nearly full support for the disk drives (this makes more than 90% of D64-images usable), but evade turbo-loaders
added some minor improvements

v1.32 (I-2006)

added DOS write commands for the D64-images (SAVE, PRINT, COLLECT, ...)
established 99.9% exactness in the TED/CPU cooperative activity — that made possible to see all (?) FLIs — this improvement made the emulator about 14% slower
commands GL (goto line) and Y (TED cycle) are added to the debugger
fixed many minor bugs

v1.33 (V-2006)

fixed some bugs

v1.34 (IX-2006)

added support for different screen sizes — many VGA and VESA modes became available — this slow the emulator down by 5-30% (it is still possible to run the emulator at 100% speed at Pentium-200 without frames skipping)
added frame skipping mechanism. It can speed the emulator up to 50%
added CFG-file support. This file is named PLUS4.CFG and contains information about video card mode, frame skipping and music card
code became compatible with newest versions of FASM

v1.35 (II-2007)

improved datasette emulation code: removed surprizing message "assign a file ...", added direct TAP format support, ...;
fixed some disk drive emulation errors (thanks to SVS of Fire);
added command line parameter support — it made possible to use a PRG file for autoload (this feature was requested by Ninja / The Dreams);
provided proper emulation of the bit 1 of the TED $1e register;
fixed some minor bugs;
THIS VERSION CONTAINS BUG WHICH MAY CORRUPT D64-IMAGES - DON'T USE IT!

v1.36 (III-2007)

some IEC emulation errors are removed

v1.37 (VIII-2007)

added possibility to use advanced command line options;
added support for the relative files at D64-images (this allows to run SVS BALsys from a D64-file);
fixed some bugs

v1.38 (IX-2007)

added possibility to use ROM and CFG files in the command line options;
fixed some bugs

v1.39 (XII-2007)

added possibility to set video mode in the command line options;
fixed one bug in the IEC error channel emulation

v1.40 (XII-2007)

added Sound Blaster support;
removed error which caused wrong loading of some C2F-files from cmd line;
added possibility to select sound hardware from the command line

v1.41 (I-2008)

improved Sound Blaster support;
fixed one little TED bug;
