I know Mame can do this. But why not zsnes to load the sample png image tv effects onto the game screen? These samples are in png image and small. This will save time on the coding the effects which nolonger need to be coding in anymore. Plus don't have to worry about the effects breaking anything. That would be awsome.
Here's my RGB phosphor simulation. It'll only look good on an LCD monitor, due to the need to have precise control over the output pixels. It properly duplicates the vertical lines effect in solid primary colors (red, green, blue) and the general mix of colors for composite colors, including white.
The filter is simple: darken the green component of odd pixels by 50%, and the red and blue components of even pixels by 50%.

I was wondering why MAME supported rendering translucent PNGs on top of the output. Guess I have my answer now
At the Mame website in the download page. These png are with the Mame build. You should find those in the c:\mame\artwork. Aaron Giles made these I think. If you have any question byuu about these I sure he can give you all the infos about different screens effects. You will be image on these good screen effects for PC screen.
No offense to the person who made the NTSC filter but... I've never seen a TV that looked that bad. From the crappy old ones to the brand new oens; none of them look as crappy as that filter.
Nearly all TVs here in Australia look like that. And of all the filters ZSNES has, I think that one does the best job of hiding the fact that a low internal resolution is being used.
personally i have never had a tv that displays like any 'tv mode' that i have ever seen in any emulator, including the NTSC filter in zsnes, maybe its just a NTSC thing (i live in the PAL region [UK]) but my tv here sure does not have dark scanlines or any of that other junk. the only filter that comes anywhere near to matching my tv's output (and believe me, its just a cheep crap tv i got for 20 quid or so) is AdvanceMames 'filter' mode, i even went as far as to check the arcade version of sonic 2 with the filter mode on my monitor against my copy of sonic 2 on my tv.
All those filters are really great ! I usually use "rgb micro" in mame though...
Having such filters in zsnes would be cooool. I like Blargg ntsc too, although his RGB phosphor simulation looks even better, it seems !
Looking forward.

The biggest problem with this simulation in SNES emulators is that the default aspect ratio is 8:7 instead of 4:3, so your moons and suns look like ovals, your character portraits look like the people are 8' tall, etc.
If you apply a filter like this, and then stretch the image to fix the aspect ratio, the resulting image looks horrendous.
The reason that I play games on Zsnes rather than just my console in the first place is the fact that I think they look much more appealing all crisp and clean on my computer screen, as opposed to on televisions. Ever try plugging an older system into a 65" HDTV? Yeah, not pretty. Emulation, you're a god-send
