hahaha, well I subscribed to it, I cant wait!

Even if you manage to simulate the look of a course triad shadow mask and dot pitch, you still have a few problems which are inherently insurmountable with LCD displays.
For one thing, LCDs are backlit, while CRTs generate their own light. This gives an inherently different look to the light.
For another thing, the spectrum you see when viewing an LCD changes with viewing angle (this happens to one degree or another with all LCDs, despite claims that this problem has been solved).
Also, LCDs have a thin plastic screen, which has different properties with regard to how light passes through it and reflects off it than the thick glass of a CRT.
This all adds up to a baseline look that is inherently different than the baseline look of a CRT. No matter what image you generate with an LCD it will never look like a CRT. To prove this, you could take some perfectly framed high-definition video of a standard arcade monitor displaying e.g., a game of Pac-Man (preferably matching the video frame rate with the monitor's refresh rate). Now play that video back on an LCD display of your choice, and see if you are fooled. That same video played back on a CRT PC monitor however could be pretty convincing. So if you are able to accomplish such a simulation, I'd be interested, because I still use a CRT PC monitor, and I will continue to do so for as long as possible; or until something that is truly as good or better comes along (I'm not a fan of "one step forward, two steps back" technologies such as LCD).

MaximRecoil,
that is true but a CRT is just not an option for every application
This just supposed to be "as close as we can get" to a CRT look on the admittedly inferior an LCD, not to replace CRT's
I have to say, behind smoked glass, my LED LCD looks pretty darn good (the blacks are much better) again I'm not saying it's CRT quality, but a 19" CRT is bigger than my whole project :lol
I can't believe Gary hasn't even started this in earnest yet and people are poo pooing it ???
Gary PLEASE don't let anyone keep you from making this!!!!

Like Bender said, this is not about replacing CRT's, just replicate as much as you can.
I truly think it CAN be done, I mean if you sat with a good digital camera on a tripod and took a screencap of a CRT screen and viewed it fullsize on an LCD it looks pretty good, granted you'll never captured the depth of a bulbous thick glass screen of a CRT or the seemingly floating pixels in the dead of black but I do think with the right programming you can at least make something that looks better than the ugly blotchy stairstep effect you get with MAME as of now.
