[0] @ !!! Sobota, 4 Kwietnia 2020 13:13 CET [04-04-2020 13:13 CET]

CSpect oprócz emulacji ZX Spectrum, pozwala na zapoznanie się z softwarem ZX Spectrum NEXT, kickstartowego projektu, którego efektem to nowa wersją Spectrum, nie tylko będącą kompatybilną ze starymi modelami ale dającą nowe, współczesne mechanizmy.

Program wymaga zainstalowanej biblioteki OpenAL (dźwięk) w systemie.

NOWSZY [ZX] #CSpect V2.19.3 29/12/2022

#CSpect 2.19.0.3 Wednesday, January 18, 2023

Massive update, with virtually all rendering components touched to properly allow for blending modes. While there has been a concerted effort to beta test this, please report any rendering oddities that you see on the Spectrum Next discord channel.
Also in this version, is a major update to audio/video syncing, producing far smoother and more playable results. The recommended command line for gamers will now be "-60 -vsync [game]". This should give full audio, and nice smooth gameplay.
General timing has also been improved, so without audio running at 60hz and vsync in fullscreen, everything should "glide" nicely again - as it used to in the C++ version.
Plugin authors be aware of a change to the Plugin system. Due to the new Audio/Visual syncing system, the emulator "could" now be running on a different thread, and as such, you can no longer do GUI/OS work from callbacks. ALL UI/OS work must now be managed via the new OSTick() callback. Like the Tick() callback, but this is always called from the OS thread, allowing you to open windows, and refresh/draw them. Please see updated plugins on my github for further example code.
Hope you all enjoy this one, it's been some time in the making - thanks to all who helped beta test it.

  • Fixed “INC A” and “DEC A” instructions
  • Fixed a crash trying to read a file from a non-existant directory

 

#CSpect V2.16.0 changes xx/xx/2022

Lots of fixes and a few new additions. Improved the new divMMC autopaging for directly loaded NEX files. Added the -mouse option to try and help MAC users a little, and also fixed up the copper when large DMA blocks were running. A nice new feature is being able to visualise both copper and Raster IRQ splits using CTRL+ALT+S (via the copper plugin). Even for non-devs, this is a funky little tool to show just how complex things can get!

  • Added directory functions to RST$08 plugin
  • Fixed screen rendering time a little.
  • on .NEX load, regs $B8-$BB are set to $82,$00,$00,$F0 - same as the OS.
  • Added reg $0A = bit 2, to be able to disable DivMMC auto mapping
  • Fixed crash when typing "BR :" in debugger
  • Added a "-mouse" command line option. This will disable the "grabbing" of the mouse.
  • When specifying an SD card image, you no longer have to specify -zxnext and -nextrom on the command line as well
  • Fixed Copper when the DMA is running and blocking CPU, now counts DMA "TStates" instead of CPU ones
  • .NEX files will automatically disable DivMMC PC address memory mapping
  • Added -divmap command line, so you can force memory mapping of the DIVMMC "on" when directly loading a .NEX file
  • Fixed a raster interrupt issue
  • Added -copwait command line so you can easily visualise where the copper splits are
  • Added -irqwait command line so you can easily visualise where the raster irq splits are
  • You can now toggle the copper and irq visualiser with CTRL+ALT+S via the copper disassembler plugin
  • You can now "set" command line globals via the Plugin interface

 

#CSpect V2.15.2 changes 29/03/2022

Updated so that the very latest OS now works by adding new Next Registers $B8-$BB, along with a few updates, changes and fixes.

Also please note, if you take over the "whole" machine to haved a full RAM machine, you will now need to set registers $B8-$BB to be able to jump to address $0000, or the DivMMC may well page in.

  • DeZogPlugin added to main distro so it remains upto date.
  • Added stackless NMI support
  • Reset register $02 added
  • Added NextRegs $B8 to $BB for DivMMC direct paging control
  • Current ROM and DivMMC registers added to rewind history
  • F6 now cycles through turbo speed settings
  • F5 Now takes a screen shot (was on CTRL+F3)
  • Fixed a rendering glitch when estimates for the right HBlank timing are "missed" and the line isn't drawn.
  • -log_cpu removed. Rewind probably replaces the need for this.
  • Updated RST$08 read/write to return values in BC,HL and DE as described in NextZXOS
  • Layer 2 banks can now be in the full 2Mb (regs $12 and $13)
  • Parallax demo updated to work with new $B8-$BA registers

#CSpect V2.15.1 changes

  • Fixed SD card access - SpecNext IMG files now boot again

#CSpect V2.15.0 changes

Some fixes and a couple of new open source extension.

  • Fixed a crash when trying to get file info on a file that can't be found (or opened)
  • Fixed ULA colour 3 (where colours are 0-15) on a loaded NEX file.
  • Fixed Border colour when ULA Palette scale set to 255, but ULANext mode is disabled
  • All RST $08 operations have been moved to a new open source extension esxDOS.dll - lightly tested
  • Added Copper Read/Write to extension system - allowing for a copper debugger/assembler etc
  • Added single byte peek/pokes to extension interface for simpler access
  • OpenTK upgraded to v3.3.2, any newer version won't install as it's incompatible with .NET frameworks
  • Added initial open source Copper disassembler/viewer - "ctrl+altc" to open
  • Open source extensions added to Github

#CSpect V2.14.8 changes

  • Fixed a L2 scrolling issue - that I'd just added.... *sigh*

#CSpect V2.14.7 changes

  • Fixed a L2 clip scroll offset issue

#CSpect V2.14.6 changes

  • Forgot to switch on the new rendering again - now done.

#CSpect V2.14.5 changes

  • Fixed L2 left clip (I think)

#CSpect V2.14.4 changes

A few fixes have been requested by devs, so I've done a quick new version.

  • Fixed L2 320 and 640 clip window
  • Fixed LD_R_A in debugger to "LD R,A"
  • Fixed a bug when writing the copper control byte, where it would reset the lower byte of the copper write address
  • Added the raster offset register ($62) but mostly untested.
  • Screen rendering now starts in the HBlank, not at the end of the line, allowing changes for the next line to take place in the HBlank.

Minor update V2.14.3

  • Fixed BIS and Warhawk crash
  • Odd crash with last version, rebuilding zip to try and fix
  • Now alerts you to a new version
  • Did more sprite window fixes
  • Altered FLASH rendering

Minor update V2.14.1

  • Added a check for AY regs above 16, as a common music driver has a bug in it
  • Timers are now reset on F3
  • IRQ TStates are reset back to 30 Pre-Tstates. This isn't correct but helps some games work better.
  • Stopped a crash on exit from fullscreen

Changes V2.14.0

  • Fixed esxDOS Read/Write so it's now returning NEXT pointer IX instead of HL.
  • You no longer need to extract ROM files to run in full SD card mode, they will be copied out the SD card image directly.
  • Sprite right edge clip fixed - I think.
  • AY registers are now readable
  • Some very basic analytics are now collected. Each startup, command line options etc. "-analytics" to disable. Please leave it on if you can, as it'll help me direct developement effort.
  • I have added my new SDCardEditor into the archive. This is very much just a beta, but lets you easy copy files from the SD card. Full editing coming on this.
  • The latest windows update now causes some nasty stalling. To reduce (but not remove), go into "settings" and search for "game mode" and switch it off. This will help a little.

#CSpect V2.13.01 March 03, 2021

  • A few fixes and some new Next hardware that's coming soon....
  • Put some guards around break point setting to check ranges a little.
  • Symbols are uppercased on load (they aren't case sensitive)
  • Fixed memory window. Any address < $10000 is not a physical address, its the 64k mapped. If you need this, use bank/offset
  • Fixed some BASIC key issues - holding down control keys etc
  • Fixed a ULA global transparancy issue
  • Fixed NEX loading and initialising of ULA colours
  • Rewrote the ULA colour system - was a mess.
  • Fixed some Timex rendering issues
  • Basic CTC timers (4) added. Timer mode only, no cascading. Timers can generate IRQs.
  • NextReg $CC and $CD - IRQ DMA suspend mode for timers, liner interrupts and ULA added
  • Z80 CTC Timer example source included in demo

#CSpect V2.13.00 November 22, 2020

Note: I am aware most virus scanners are rejecting this. Apparently it's because I open files in "shared" read/write mode. This is so that SD cards can still be written to while the emulator is running. You'll need to add an exception if you wish to use it.
This is a special 'experimental' release so that everyone can try out the new "rewind" feature in the debugger. Specifying -rewind on the command line, or typing 'REWIND' in the debugger will enable/disable it.
This will then let you step 'backwards' using SHIFT+F7, undoing whatever the CPU has just exectued. Memory and CPU state should be solid (along with MMU and ROM usage), and I've started to add in sprite access as well - but this is more untested.
It's good fun, and super handy for debugging when you need to just roll back a little bit....
Fixed physical breakpoints in the plugins

  • (Highly) Experiminetal "rewind" debugger feature. Simply press SHIFT+F7 to step back. Currently tracks all RAM access and Sprite port access.There's bound to be HEAPs of issues and bugs with this, but for simple debugging, it should be fine.
  • Added UnStep in plugin system
  • Added "REWIND" debugger command, to allow you to switch the CPU history on/off dynamically
  • Added Debugger message display. Now reports errors when you use a non-existant label etc.
  • Fixed a bug in the rewind of MMUs
  • Swapped to 2.13 coz I was bored of 12.??

#CSpect V2.12.38 November 19, 2020

  • Minor changes and fixes...
  • Added NextRegs $2C and $2E (DAC mirrors)
  • DMA read flags (Bit 5 and Bit 1) added and fixed.
  • Added "_" to BASIC key detection
  • I "think" I've fixed the stuck BASIC mode keys (where: just gets stuck and repeats....)
  • Added OpenAL32.dll to the zip.... turns out that's allowed. on loading of a NEX file, NextRegs are set to what the OS NexLoad sets
  • 32bit mode should work this time....in theory

#CSpect V2.12.36/35 November 11, 2020

RAM is now filled with random bytes on power up to help simulate the real machine -fill=$XXXXX allows you top specify a specific byte sequence to fill RAM with

  • Debugger: general layout adjustment.
  • Debugger: text colour changes when user bar over the top for easier reading
  • Debugger: $ added to all hex numbers
  • Debugger: Hex numbers are now coloured for easier spotting

NOWSZY [ZX] #CSpect 2.12.18 13/04/2020

#CSpect V2.12.18   Monday, April 13, 2020

Couple of bug fixes for devs....

#CSpect V2.12.18 changes

  •     Fixed Layer 2,320x256 clip window
  •     Fixed a crash in Layer 2, 320x256 rendering
  •     Fixed NextReg0 (machine type) initialisation bug

#CSpect 2.12.17   Saturday, April 11, 2020

Another day, another version. This one for some devs who are trying to use the 1bit tilemaps, and another minor update for plugin writers.

#CSpect V2.12.17 changes

  • 1Bit tilemaps now use Global Transparency for it's transparency, not the tile index
  • Have added GetSprite() and SetSprite() to iCSpect interface for plugin writers

#CSpect V2.12.16  Friday, April 10, 2020

Another very minor update for plugin writers. This gives access to sprite image memory, and undoes a "fix" that wasn't right....

#CSpect V2.12.16 changes

  • Reverted .NEX border colour palette change, was just wrong.
  • Added PeekSprite(address) and PokeSprite(address,value) to iCSpect interface for plugins

#CSpect V2.12.15  Tuesday, April 07, 2020

This release is specifically to add to the plugin API, allowing plugin devs to control the debugger including single stepping and break points.

#CSpect V2.12.15 changes

  • Plugin API TICK() now called while in debugger mode
  • Plugin API can now control the debugger using the new extended eDebugCommand enum
    • remote command line switch added, to disable the "visible" part of the debugger

#CSpect V2.12.13   Sunday, April 05, 2020

So this includes a few fixes users have found in the last version, including an important OS one - hence the quick release.

#CSpect V2.12.13 changes

  • Fixed GetRegister() callback
  • Fixed NextReg 0x05 reading
  • Setup some of the Nextreg on reset (also helps reset a bit better)
  • Fixed bit 3 of new NextReg 0x8E, which fixes dot commands (and sprite editor exiting)
  • Changed number of scanlines to 262 (HDMI) for 60Hz
  • Fixed a crash in plugin creation
  • Added pluging "eAccess.NextReg_Read" type (untested)
→ [ZX] CSpect 2.12.5 6/01/2020

CSpect V2.12.5 Monday, January 06, 2020

Fixed plugin loading. This was due to the new loading/reset system that was nuking loaded plugin mappings.I've also added a "Tick" to the plugin interface which gets called once per emulated frame, along with a debugger call which allows you to tell CSpect to enter the debugger. This is handy if you need to debug the operation that "just" happened.
Lastly... I've included a very simple plugin example, along with the interface .CS files to look at.

changes

  • Border now comes from fallback colour if paper/ink mode is 255 (as per hardware)
  • Fixed Plugin loading. Was broken due to new system loading+resetting.
  • Added new "Tick" to iPlugin interface, called once per emulated frame
  • Added Debugger() call to CSpect interface, allowing you to enter the debugger from the emulator
  • Added Plugin example (and current interface)

CSpect V2.12.4 Friday, January 03, 2020

Another minor fix to fix a memory access bug, and a new MMC folder issue that appeared in the last couple of versions.

SNasm 2.0.21

  • Added “SLL” instruction

changes

  • Fixed memory reading of Layer2 mapping in $2000-$3fff
  • Fixed MMC path, it was being reset when loading SNA/NEX from the command line.

 

→ [ZX] CSpect 2.12.3

#CSpect V2.12.3

This is a minor update to fix Lowres and ULA scrolling. ULA X scrolling now uses the 2 new NextRegs - $26+$27.
It also fixes an annoying startup issue where if you didn't start in the EXE path, it just wouldn't start properly. This was due to the new plugin system, but should now be fixed. (fingers crossed). I've also added the missing LDWS instruction to SNASM

SNasm 2.0.20

  • Added “LDWS” instruction

#CSpect V2.12.3 changes

  • Lowres scrolling fixed.
  • Added ULA Scrolling registers $26 and $27.
  • Fixed HL being set to $10000 after reading a file at the end of memory...
  • Fixed a command line startup issue when not started in the EXE path

#CSpect V2.12.2

This update is a little different, as it add's the ability for users to write their own "plugins". These plugins can take over memory read/write actions, port in/out's and Next Register access - or all of the above!
They can also query the Next's memory, ports, Next registers and Z80 registers, making it pretty useful for folk to add new toys, or add things like logging or profiling etc.

#CSpect V2.12.2 changes

  • Changed 320x256 mode to use Y/X orientation (0,0)=$0000, (1,0)=$0100, (2,0)=$0200. (0,1)=$0001,(0,2)=$0002 etc...
  • Plugin system can now get/set Z80 registers
  • A better reset on load of an SNA/Nex file. Should be a complete system reset now...
  • 320x256 Layer 2 screen mode added
  • NextReg $70 added ($10=320x256 mode)
  • NextReg $71 added. MSB of Layer 2 XScroll added
  • Added Port 0x123B extended memory mapping mode added - using bit 4 to select (untested)
  • A new plugin system added, so that folk can add their own toys or support custom hardware. See CSpectReadme.txt
