One question, is this image a capture from a real zx-spectrum (TV) or from an emulator (PC) ?

> Reply (by dpla-fr @*?): as long as this image [PNG format] can be converted (back) into the ZX Spectrum format [e.g. SCR] losslessly (after cropping the dim white border to get a 256 × 192 px image), either methods are possible. Actually in this 'screenshot' (which looks like a conversion, not e.g. an edited photograph), leaving apart the questionable size of the border, only the RGBI values look arbitrary. {They use the trivial 192 number, which is commonly used as the medium value out of 255 shades, and might look too dim to me, while 205 turned out to be the preference in the demoscene. More choices exist, e.g. by preserving the reddish CRT effect, but the scanlines and display factors seem to hamper any consensus.}
