Enhancement request...

Dear razOred,

Would it be possible in the future to a scan line option?
As in a video filter?
That would be awesome for us lcd tv users and would give that "real"
arcade feel to most games.

I have no cleu if this is even possible, but IMHO it would be awesome.
For example: VC Arcade game Ghouls & Ghost has a configurable scanline option.

If this could be implemented It would take the hassle out of buying a slg3000 
and upscaler in order to get scanlines on a lcd tv.

Looking at all the fantastic ports you did to Wii, I know you also are a retro 
game lover. This would make sense ( if possible )

Anyway, can;t get enough of your awesome port!

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.
