To quickly save the Spectrum's display to a PNG file
On the File menu, click Save Screenshot.
A screenshot of the Spectrum's display will be saved to a PNG file in your
Pictures folder.
To change the location where screenshots are saved:
On the File menu, click Save Screenshot In.
The filename will be in the format [title]_[sequence].png,
where [title] is the title of the currently loaded program (or Untitled)
and [sequence] is a sequential number that increases with each screenshot taken.
Tip
You can also use the shortcut key, F4, to quickly save a screenshot.
For best results, pause the emulator so that the screen doesn't update before you get a chance to save it.
The quick save feature is designed for convenience and may not offer the same level of control
Note
The size of the quick saved screenshots is determined by the settings in the Screenshots section of the Advanced tab of the Options dialog.
