ZXSP can load z80 files up to version 3 of this file format.

Use .pict if you want to load them with standard graphics programs etc, for this is the only format they will understand. Currently disfunct features Currently the edit menu is not supported. I'm working in them.
Fast modes are still under construction.
And the options window. Sound output Sound output is resampled to 44.1 kHz mono. You can feed the sound into the ear jack of a real Specci and it will load from it. Sound emulation is currently very good. AY sound generation is very close to the original.
