Topic: Non Interlaced PAL fields
As the post title sounds contradictory, what I'm referring to is using 720x576i however rather than one of the fields starting offset by half a line, both fields start with the same offset. Causing both fields of 288 lines to overlap. In effect reducing the resolution down to 288p.
From what I can gather the Acorn Electron in mode 0 uses 640x256 PAL @50Hz. With the above change and using the center 512 lines for display of the 576 available, a 640x256p @ 50Hz could be achieved.
Is that what the actual Electron did?
If it's not clear what I'm asking, it's described on the rigacci site in the Non interlaced modes section.
I think at the moment, the 576i mode outputs the 2nd field offset by 1/2 a scanline so that interlacing occurs. Would it be possible to add a 256p mode and tweak the VideoTiming module to accommodate it?
