InkSpector 2 is an accurate Sinclair ZX Spectrum emulator for Windows. The previous InkSpector 1 screensaver page has been archived here

Features:

• Emulates accurately all ZX Spectrums from the 16K model up to the +3 (all code has been re-written since Inkspector 1), including emulation of the +2A/+3 floating bus behaviour.
  
• Emulates many common peripherals, with the ability to "hot patch" them to the currently running machine.
  
• Live snapshot previews when loading and saving supported files
• Support for most common snapshot and tape files, including loading from within .zip files
  
• Full RZX recording support: playback, recording, importing (allows existing recordings to be extended) and verifying (to test whether a recording completes without losing sync).
  
• Flexible peripheral configuration, allowing them to be configured for specific ZX Spectrum models or existing snapshot or recordings, e.g. allows the Chuckie Egg .rzx recording to be configured to attach a Fuller Orator device to allow the game's speech to be heard.
  
• Detailed Microdrive cartridge information with live updates as the cartridge is modified
  
• Detailed +3 disk information, with sectors coloured depending on recent access times to show how the disk is being read or written
  
• Debugger, with ability to load assembler listing and symbol files to aid debugging. Single step times are shown against the instruction. Built in single instruction assembler. Flexible breakpoint system. Flexible find system (e.g. "ldir" or, for example if assembler symbols have been loaded, "ld a,(my_symbol)"). Full ROM and RAM paging support.
  
• Memory window containing 4 tabs which can be individually configured to follow an expression (e.g. "pc- 100"). Any assembler symbols loaded are highlighted in the hex dump.
  
• Keyboard assist which means no more guessing how to enter a command into the 16K and 48K Spectrum BASIC command editor, instead just type the command in full (e.g. 'pr.at 10,20;"Hello there!"') and InkSpector will do the rest.
• A headless command line interface version is included, which may be used to perform snapshot conversions, snapshot disassemblies and testing .rzx recording files.
• A full Z80 macro assembler, built into both the GUI and CLI tool
  
• A simplified screensaver containing the re-written InkSpector 2 emulation code is included but no longer includes 3D support. InkSpector 2 may be installed side-by-side with InkSpector 1 if you wish to continue to use a 3D screensaver.
• Many more features too numerous to mention!

System Requirements:
A PC running a 64-bit version of Windows 7 or later.

Debugger

This shows the basic debugger, with the 'Assemble to memory' option being used.

This image shows the debugger's assembler .lst and .sym file support in action. When loading a snapshot, Inkspector attempts to load a .sym (assembler symbol file) and .lst (assembler listing file) with the same filename. When available and loaded, they are used to improve the disassembly display and make the symbol values accessible anywhere a memory address can be entered into Inkspector - not just in the debugger window (note at present this functionality is turned off by default. It's enabled by switching on the two 'Attempt to...' options at the top of the Debugger options page).

Memory

This screen shows the memory window. Expressions may be entered into the box containing 'pc' on this screen, and if  'Follow' is checked the memory tab will automatically re-evaluate the expression and follow it as the debugger steps through code . Hex bytes shown in blue indicate there is a symbol with a value corresponding to that byte's address. Clicking on the byte will show the symbol name. In this screenshot, address $abd1 has been clicked on, which corresponds to the symbol 'MoveBaddies.exploding'.

Keyboard Assist

To make it easier to enter commands into the 16K and 48K Spectrums, Keyboard Assist may be used. Type out the BASIC command in full, and keyboard assist will enter them for you (taking care of any 'E' modes, etc., that may be required to select the commands). Commands may also be shortened with a period, as long as it doesn't make them ambiguous. E.g. "pr." expands into PRINT. But "co." will not expand as it could be interpreted as CONTINUE or COPY. In that case "con." or "cop." could be used. Keyboard assist also works in 128K (and later) BASIC but of course without as much benefit.
