This is something I too have been thinking about. The upcoming (0.1) release
provides the option of 240p mode which adds scanlines (assuming you have a SD
CRT).I was thinking about adding a "simulated" mode to the 240p option that
would provide the same look on HD displays. So, I will give it a shot, but it
won't happen until 0.2.

That's incredible news!
I really hope you can pull this off!

I don't think it makes sense to simulate scanlines in 240p mode. In my opinion,
that should be left as a 'pure' output for users of CRT displays or specialized
upscalers. Instead, consider allowing for simulated scanlines in 480p mode by
simply line-doubling (2x scaling) and allowing for the intensity/opacity of odd
lines to be adjusted. This should also result in improved compatibility with
modern TVs (which are not renowned for sane 240p support). Also, the higher the
resolution employed, the lower the chances are of the TV's scaler ruining the
effect. For example, Sony TVs allow for the 'Display Area' to be set to +1 in
480p mode which doubles the effective display area up to 960 pixels perfectly -
as opposed to stretching to 1080 pixels and producing artifacts.
This approach to line doubling is pretty much how the Micomsoft upscalers do
it. For what it's worth, they default the intensity of scanlines to 80. That's
on a scale of 0-127 where 0 is black and 127 means that all lines have the same
intensity.

Just to add also: doing it in 240p mode would mean that lines containing unique
content are darkened. Obviously, that's nothing like what happens on a real CRT
and I've never seen this method employed in any other emulator. It always
entails scaling and inserting black/darkened lines (e.g. 2x scale with the
duplicated lines darkened). The reason for not necessarily inserting black
lines is that CRT displays usually have a natural bloom effect on the lines.
Putting aside the new methods for CRT simulation (using high resolutions and
complicated pixel shaders), allowing for the lines to be duplicated with a
lower brightness is a pretty good method for approximating that effect. Indeed,
that's why the XRGB-3 and XRGB-Mini use that exact method ;)

If the Wii can pull it off, a filter that resembles this phosphor filter would
look even better than scanlines:

It seems like there are only mockups there and no code, but the look is really
nice. There is a 2x mockup here:

Please enhance the PC engine and PC engine CD support. Please continue the
project. Many people want a good pc engine emulator on wii.
