for emulate it I use realspec (also UnrealSpeccy works very fine!)
I have found some games/demos in trd format that uses this mode. With multicolor effects and without gigascreen mode you can see a fast change color between 2 near pixels (sorry for my English ;)). You can find any documentation. You can find some examples of gigascreen into Power of Sound Web site:

Gigascreen was used by Pentagon. In this case you haven't flickering effects

I understand you well. Thank you for the url. We will examine this documentation.

May I ask what is zx-box project?

Multicolour is not the same what gigascreen is.
Multicolour - everybody knows what's that.
And gigascreen is very popular format on Spectrum; many demos use it, some games, Leszek Chmielewski's convertor, and the best graphic utils uses it too. Was it BGE...? I can't remember now, but several.
To Sprinter screw: is it possible for you to make the mode to stop blinking? They say there is some piece of hardware which can achieve it on Speccy...

If you wanna take a look, it is made well on "z80 stealth" emulator (on F7 as far as I know).

is the implementation of tcp/ip on ZX Spectrum.

>To Sprinter screw: is it possible for you to make the mode to stop blinking?

because Sprinter haven't gigascreen support. :(

So it's impossible to stop the blinking of interlace (gigascreen) mode?

I don't know... ask to Alexander :) I suppose that it is possible.

Probably it is possible to create in PLD. The Circuit of the gigascreen is easy. But it not means creation this mode soon certainly. We have a plan of Sprinter progress already.
