Equal trade for Scan Doubler / Flicker Fixer

[patrik]

@Zac67:

Apart from needing double as much memory, they would need double as fast memory as the pixels would be sampled at ~28MHz and output at ~56MHz compared to ~14MHz and ~28MHz now. This if they would stick to their current design and just scale it to be able to manage Super Hires.

(edit):

I also forgot that they also need a faster D/A if the separate ~56MHz pixels are supposed to be distinguishable.

@J-Golden:

They will drop every other pixel on the horizontal lines the image is made up of.

The ScanDoubler II can as far as I understand the german manual manage super hires and if that is correct, it is the only one capable of that as far as I know.

The majority of aga scandoublers/flickerfixers are very bad and that is not because of them not supporting super hires - which imo is a minor flaw, but they make the aga graphics look like ocs graphics by not supporting the 24-bit aga palette.
