features
cpu
Z80: all (un)documented commands and flags
memory
Pentagon 128/512/1024 and 48K ROM
TS-Configuration
Scorpion 256/1024 RAM and 64K ROM
Scorpion PROF-ROM with SMUC support (128/256/512K)
KAY-256/1024 and 64K ROM
ZX Evolution
Profi 1024 RAM/ROM and memory mapper
ATM TURBO 1 v4.50 512/1024 RAM, 64-1024K ROM
ATM TURBO 2+ v7.10 128/512/1024 RAM, 64-1024K ROM
cache 16/32K
CMOS/RTC: russian chip (512Bu1, 64 bytes, 1st day is monday) or
pc-compatible (DALLAS, 256 bytes, 1st day of week is sunday)
SMUC RTC and NVRAM (24LC16)
sound
beeper, tape saving and loading tones
AY-3-8910/YM2149: excellent sound emulation, including digital
and unusual effects, parallel ports on R14/R15 are not emulated
Turbo-AY (Turbo-Sound): two AY(or YM) chips by PoS and NedoPC schemes
TurboSound FM: two YM2203 chips (6 AY channels + 6 FM channels)
also there is 'unreal' (not available in real Spectrum) mode:
playing AY music using digital player - emul plays three sound samples
with volumes and frequencies taken from corresponding AY registers
and 'pseudo-turbo' - two parallel YM chips with some phase shift
two covoxes - Pentagon (port #FB) & Scorpion (port #DD)
SounDrive
saving sound to WAV or VTX (VTX - good format for AY sound, much
more compact than PSG, but you need lha.exe somewhere in %PATH%)
General Sound - FX & MOD player through BASS sound system.
You can save music and listen it in your favourite mod-player
General Sound low level emulation (including internal Z80 on 12MHz,
512Kb onboard memory, internal ports and DACs)
BASS offers higher quality and more sound channels than low-level
emulation. Low-level emulation is useful for programs altering the
firmware player and using second Z80 for their own needs. In general,
use BASS for games, and low-level emulation for advanced sound/music
editors (RIFF tracker)
video
several video drivers, from simple and fastest to complex bi-linear
filtering, that upsamples Spectrum display to 512x384 * 64 colors;
'noflic' filter is specially for programs fast switching two screens
to get more colors;
several chunky filters for 21st century demos
amazing video filter: Anti-Text64. Designed for reading e-zines.
It converts 4x8 fonts to 8x8 or 8x16 on the fly and saves your eyes
multicolors are fixed for Pentagon & Scorpion, 1T screen update
for all border effects
able to emulate scorpion timings, including scorpion border update
nopaper mode for debugging border effects
flash-color (using 128 ink colors with black paper when FLASH bit on)
hi-res modes: Pentagon 512x192, Profi 512x240, ATM
(works with 'double' video filter)
ATM-TURBO color video modes (works with 'double' video filter):
text mode 80x25, EGA mode 320x200, 640x200.
To use custom text-mode font, place your "SGEN.ROM" to unreal directory.
Don't use border=none with ATM video modes
Pentagon 384x304 mode [see ZX-Guide#2, AlCoNews#32]
Pentagon color-per-pixel mode [see Info Guide#8, #9]
hardware multicolor
attribute port #FF
tune-up video/sound with hotkeys
change video settings, such as number of t-states/frame, t-states/line,
fix with grey+, grey-, grey*
t-states/frame is a computer speed, so it's easy to adjust speed in
fast (or slow) games in very wide range for comfortable playing
alt+grey*, grey-, grey+ selects soundchip (AY/YM) and
stereo mode (ABC/ACB), or palette
beta 128 disk interface
implemented all FDC WD1793 commands, including read/format track
traps for read/write sector - more then 256 times speedup
tape
full TAP and TZX support
CSW support
tape browser
auto-start tape when accessing to ROM load routine
fast loading: UnrealSpeccy is able to recognize loader logic
and speed up loader by removing delay loops and edge detection loops.
(Of course, UnrealSpeccy leaves original t-states timing,
so max speed mode must be enabled for fast loading - press NumLock)
With this technique any 128K game may be loaded in 10-20 secs.
I've developed this feature independent from RAMSOFT, but looks like
they used the same idea in RS 0.90.38...
For really fast loading, also choose 'normal' video driver
IDE
UnrealSpeccy is able to use KAY, SCORPION and ATM-2 IDE interfaces with
two devices on it (hard disks or CD-ROMs)
for hard disks you may use image file or Spectrum drive, connected to
computer. CD-ROM requires physical or windows-level emulated device
schemes supported:
Nemo - controller for ZX-BUS manufactured by Nemo and NedoPC
ATM - ATM TURBO 2+ v7.10
Nemo(A8) - Nemo scheme modification: uses A8 instead of A0 to
select high/low byte of 16bit data (easy to
transfer sector with just two commands INIR:INIR)
SMUC - IDE controller for ZS Scorpion
modem
ISA modem, configured to use COM1 ports 03F8-03FF
translated to Spectrum's ports #F8EF-#FFEF.
Modem interrupt (translated to Spectrum NMI) is not emulated
Host computer should have installed windows driver for real modem.
At least ping/dns by Kamil Karimov tested and works fine
with empty 'modem initialization string'
input devices
fully customizable keyboard
copy text from clipboard via emulation of Spectrum keyboard
AY-mouse (KORVET mouse, connected to AY-3-8910/12 port A)
kempston mouse with adjustable speed and swap-buttons option,
mouse wheel included (D7..D4 in buttons' port or UP/DOWN keys)
kempston joystick on keyboard
kempston joystick on mouse (joystick will follow mouse cursor)
mouse wheel and buttons can be bound to any zx keys or kempston
PC joystick/gamepad can be bound to any zx keys or kempston
sticky keys mode [stolen from ZX_Emul, read description there]
autofire (with adjustable key and period)
files
reading:
SP, SNA and Z80 (all versions, 48k and 128k)
TAP, TZX, CSW
FDI, TRD, SCL, TD0, UDI
if disk image does not contain boot.B, it may be appended.
Disk images for every drive may be loaded automatically
at start of UnrealSpeccy
HOBETA format - appends file to existing disk; if no disk, then empty
TR-DOS disk will be created. Best use with command line:
unreal.exe prog.$B prog.$C <- will be placed on same disk
You can also load it from 'F3' dialog, but only by one file
writing:
SNA 48k and 128k
TRD, FDI, UDI
TD0 (saved unpacked, so expect saved file larger than loaded)
SCR, BMP (screenshots)
WAV, VTX
disk images converter:
emulator can open disk image in any format (TRD/TD0/FDI/SCL/UDI)
and save it to any other format
leds
1. AY volume/status. Just for fun. White color - tone, yellow - noise,
green - envelope; also shows YM2203 and GS volumes
2. perfomance leds. One displays how much Z80 t-states is between two
interrupts. While watching some demo you can see how much time
takes one or another effect. Second led shows PC framerate - at
normal speed it must be 50. If it is less, then your CPU is too
slow, and sound may be jerky - try to select faster video driver,
disable some devices, increase skipframe or decrease t-states
per int. When running on max speed, framerate shows how fast you
computer is. For example, 800 fps is 16 times faster than
Spectrum, so average game will load in 20 secs.
3. input led. Shows which input devices are active - keyboard, mouse,
kempston joystick. For keyboard, displays queried keyrows.
One example: I've noticed, that in KOL0BOK2 intro active keyrows
are <B>-<SPACE> and A-G. <SPACE> is an exit, but why program
scans <A>-<G> ? I've pressed <A>, and I saw that now program
queries <Y>-<P>. After pressing A+P, program queries <CAPS>-<V>.
When pressing A+P+X active keyrow areonly <B>-<SPACE>. So, I've
found cheat without digging in program code! (Another way was to
set breakpoint on reading port #FE and analyze code nearby)
4. loading led. When saving/loading from disk, emulator shows
blue or red diskette. When formatting track, yellow disk is
displayed. When loading from tape, emulator displays
cassette picture and progress for current block (or 'PS' - tape
silence)
5. local time - for those ZX Spectrum fans, who spend all their
time with virtual Spectrum
6. on-screen watches - display used RAM and ROM banks in last frame,
count user-defined expressions
7. using leds on AT keyboard to display AY amplitude peaks
leds look strange when flash-color is enabled. It's not a bug
monitor
software that in PC world is called 'debugger', in Spectrum world
is often called 'monitor'
find text or code.
Using mask: code matches when ((code & mask) == (pattern & mask))
unlimited number of code breakpoints
conditional breakpoints of any complexity, uses C-like expression
syntax (with this feature can be easily done: breakpoint on range,
breakpoint to port in and out, on instruction, etc..)
memory access breakpoints (on reading/writing/executing of given memory
areas)
built-in Z80 assembler/disassembler
save-load memory blocks
disk editor
ripper's tool: for ripping routines with their data.
Marks which bytes were read/written, and saves whole 64kb memory,
replacing unreferenced bytes with user-defined byte (default is #CF)
hotkeys to save/restore cursor position in disasm window
hotkeys for location instruction operand in Z80 or dump window
on-screen watches: show memory areas addressed by register pairs
GUI
all settings, that present in INI file, may be changed in GUI
(but will not be saved, for permanent effect edit INI file)
easy entering POKEs, if you don't want to use monitor or use
HEX addresses. Delimiters for numbers are space, comma, colon,
semicolon - so POKEs can be cut'n'pasted from any cheats collection
loading from archives. Now supported: CAB,ZIP,RAR.
You can add your own archivers to INI file
----------------------------------------------------------------------
system requirements
Windows 95 or higher, or NT (not tested).
Windows 2000/XP/2003 are required for real HDD support.
for running UnrealSpeccy you need:
Pentium-166 CPU MMX for basic functionality
Celeron-266 CPU for Profi/Pentagon/ATM/Anti-Text64 hi-res modes
Celeron-400 CPU for GS low-level emulation
UnrealSpeccy eats only 12Mb of RAM, so
if you've started Windows, then memory is enough
2D accelerared video card with hardware support of
video overlays and color keying for overlay modes
3D accelerared video card for hardware chunky bilinear filter
2 Mb of video memory in fullscreen
4 Mb of video memory for windowed mode
16-bit sound card [optional, but recommended]
if you have such hardware, but emulator runs slow, try the
following:
0. install latest directX and videocard drivers
1. increase sound buffer size (especially for Win95) in INI file
2. select video filter='small', video driver='ddraw'
3. disable vsync
4. set 'ShareCPU=0' in INI file
5. do not use General Sound low-level emulation
6. do not use YM2203
7. set 'skipframe=4' in INI file
8. set 'Frame=30000' in INI file (if nothing else does not work)
9. disable sound (without sound emulator runs much faster)
this should help
----------------------------------------------------------------------
command line parameters
/i <file> specify custom INI file, default:
emulator_executable_filename_without_extension.ini
/l <file> specify labels file, default: user.l
/b <file> specify breakpoints file, default: bpx.ini
----------------------------------------------------------------------

Alt-C breakpoints manager
Alt-Y switch active sound chip in Turbo-Sound mode
manager can handle 3 types of breakpoints:
1. conditional breakpoints and on-screen watches
are using C expression syntax.
operators (in priority order):
() ! ~ M(x) -> * % / + - >> << > < == = <= >= != & ^ | && ||
operands:
a,b,c,d,e,h,l,bc,de,hl - common registers
a',b',c',d',e',h',l',bc',de',hl' - alternative registers
ix,iy,pc,sp,i,r - control registers
FD - memory port #FD (also known as #7FFD)
PG0, PG1, PG2, PG3 - TS-conf page registers for memory windows at #0000, #4000, #8000, #C000
OUT - port used in 'OUT' command (or 0FFFFFFFF when no outs)
IN - port used in 'IN' command (or 0FFFFFFFF when no ins)
VAL - read/written value to port (only meaningful when OUT !=
0FFFFFFFF or IN != 0FFFFFFFF)
RD - address used in memory read operation
WR - address used in memory write operation
MDT - data read/written to memory
numbers - hex, must start with digit: DFFD - wrong, 0DFFD - right
characters - must be enclosed in single quotes ('A','B',etc..)
All calculations use 32-bit unsigned interger arithmetic.
If you are not familiar with C, use brackets as much as possible, due to
non-intuitive operator's precedence, e.g.
out & 0FF == 0FE is treated as 'out & (0FF == 0FE)' <- always 0
M(x) is byte from memory address x (same as x->0)
'=' is an alias for '==' (for Pascal programmers)
examples:
(out+1) | (in+1) - in/out to any port
(in & 8001) == 0 - read keyboard row from <B> to <SPACE>
!(out & 1) - any out to port #FE
(out & 0FF)==0BB && (val==0F3 || val==0F4) - reset General Sound
(out & 0FF)==0FD && (val&7)==3 - set 3rd memory page
(FD & 7) == 3 - the same
M(pc)==0CB && pc->1 >= 10 && pc->1 <= 17
- set break on executing instruction "rl <reg>"
I hope, these examples will be enough to get idea
note: double-click on breakpoint to edit it
2. execution breakpoints (also set in CPU window by pressing SPACE).
In manager window it is easy to setup breakpoint on execution
range like 6000-FFFF
3. breakpoints on reading/writing memory. Similar to execution
breakpoints, but have flags "R" and "W" to issue interrupt on
reading/writing memory address (flags may be set together)

----------------------------------------------------------------------
bugs and incompatibilities
some programs, such as Manic Miner and Lode Runner, require
old 48K ROM (1982.rom), while some other programs require
ZX Spectrum 128 ROM (48for128.rom + 128tr!.rom)
some TR-DOS programs (Unreal Megademo by KSA, Street Fighter)
work only if TR-DOS traps are disabled and all delays enabled
Profi service ROM can work only when all TR-DOS delays are enabled
Bumpy does not work in default configuration, it tries to read port
#FFDF for kempston joystick - so disable kempston mouse before
playing [bug found by Paul Pavlov]
sounddrv=wave does not work with CTSB128PCI (Creative Sound Blaster),
there is a bug in drivers for this card. [bug found by Nuts]
some ABS adventures (ALIEN.SCL, LENIN.SCL) do not work with TR-DOS 5.04TM,
use version 5.03 - it is most compatible [bug found by Paul Pavlov]
Vixen 1,2,3 - incompatible with SounDrive [bug found by Paul Pavlov]
Fernandez - incompatible with SounDrive [bug found by Shadow Maker]
port #FF sometimes is not responding when SkipFrame!=0
(the same to SkipFrameMaxSpeed!=0 and max speed mode)
Scorpion 'MAGIC' generates NMI even if PC < #4000, but shadow
monitor is not designed for this situation and may crash
CacheVox by AlCo requires TR-DOS delays enabled and [BETA128] IL=1
If the emulator after returning of focus seems to have a sticky key,
press Scroll Lock, deactivate blinking key, then press Scroll Lock again.
If emulator control keys work wrong after returning of focus, press Enter,
and keys must go normal.
If emulator hangs with General Sound, try DSPrimary=0.
If emulator crashes with General Sound, try GSType=Z80.
If Kempston Joystick doesn't work, go to menu, press NumLock there,
then return.
In case of bad sound, try DSPrimary=1 (may crash emulator eventually!)
or SoundDrv=wave in .ini.
Screenshots are saved to the emulator directory.
Files to read and write via debugger are situated in a current directory
(which is seen by F3).

UnrealSpeccy is completely freeware. You may use this emulator
and its sources without any restrictions. You may use the
sources in your own emul or to release bugfixed/new versions.
in this case you do not have to release updated source code,
(unlike GNU Public License requires, for example). You may port
emulator to any other platform (but there are many
MSVC-specific language constructions, so it's doubtful that
you can compile it with another compiler)
