Zero v0.8 is released. Zero is a Spectrum Emulator for Windows. Zero is the new Ziggy. Ziggy is a ZX Spectrum emulator written in C# on the .Net platform. It currently emulates the 48k and 128k models with a very high degree accuracy.

Ziggy currently sports the following features:
* 100% accurate... oh ok then, highly accurate 48k and 128 emulation. Not kidding. ;)
* Support for both the beeper and multi-channel AY sound.
* DirectX and GDI support. Works best with DirectX though. :)
* Support for snapshots (sna, szx, z80) and tapes (pzx, tzx, tap, csw)
* Save screenshots from emulator in bmp, png, gif and jpeg format.
* Debugger with stepping facility.
* Tape browser with support for accelerated loading via various (read 2) means.
* Ability to run files from command line, drag and drop. If file associations are enabled,
double-clicking from explorer will launch Ziggy.
* Supports issue 2 keyboards, late timings and a host of other speccy idiosyncracies.
* Full screen mode.
* ULA Plus support.
