Given that people have faithfully recreated the "flaws" of NTSC to emulate home console games accurately on today's displays (check out http://www.fly.net/~ant/libs/ntsc.html), it's only a matter of time before MAME integrates "CRT Mode" for video output, taking advantage of the LCD of that day with 8,000 x 6,000 native resolutions.  :cheers:

And for actual games? I'm sure someone could make a converter box that takes regular old harness video and accurately upsamples to simulate that classic look. (not like that horrible D3D upsampling, yuck!)

As soon as I get the time, I'm going to work on CRT emulation and better vector emulation for Mame.

Dear GOD.  Some one is actually PURPOSEFULLY trying to emulate composite dot crawl and color bleed???

The only part that I want to emulate is the shape/falloff of the pixels, the shadow mask, etc.

It seems his goal isn't really CRT emulation but crappy analog signal emulation.  I mean, that composite dot crawl would look teh same on a CRT or an LCD.  (Maybe more apparent on a higher res LCD)

Looking at this grid, the only 'CRT Emulation' is just generic 'add scanlines! Woo!'.  Though I am impressed at the effort he's made at emulating low quality signals, I just don't see the real BENIFIT.  I'd rather get S-Video out of a NES then composite for example.  I'm getting component video cables for my Xbox's to use on 27" Sony Trinitron CRTs just to get a clearer signal, even if it's still low def 480i!

Hmm, might have to start working on this. . I have a Wells Gardner D9500 sitting right next to my LCD with multimon for comparison purposes. :)

If you ask me, composite makes anything look worse.  Component, even on standard def CRTs is vastly better, it's nice, clear and sharp, like looking at an 15khz arcade monitor over RGB.  One of the main reasons I go with component or at least S-Video on a TV if I can for my gaming events.  They even make S-Video cables still available in stores that work on the SNES.  (And N64 and GameCube)

The arcade monitor look is definitely what I will go for.  When I was playing 2600 as a kid, I wished that it would look like an arcade game. :)

Myself, I don't have room for cabs and settle on TVs.  I also need portability as me and others do gaming events at anime cons and stuff.  Right now I'm working on a setup for Outrun 2 using the Xbox.  I'm getting a pair of 27" Sony Trinitrons made in the last 8-6 years all with component video input.  YPbPr 480i component isn't as good as RGB 480i component on a technical level but I'm pretty certian that 99 out of 100 people couldn't tell the difference if they were side by side.  It's as close to an arcade quality signal as I can get and I say it does pretty good.  The setup will be two TVs side by side, matched pair of racing wheels with shifters and pedals and of course two networked copies of Outrun 2.  Even little 11"x4.25" marquees to be printed up and sit atop each television: http://i254.photobucket.com/albums/hh100/AshleyAshes2/Outrun2Marquee.jpg

Basicly, as close to having a racing cab as you can get without actually building a cab.

High quality video input is also a concern.  Especially as the LARGER the TV the more apparent that video artifacts, particularly from composite video becomes apparent.
