Zero v0.6 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. ;)

* 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.
