Alternating black and white pixels causes a high frequency luminance signal, which causes interference in the chroma signal (when using an antenna or composite cable)

This interference causes flicker between different colors because the chroma signal's phase is shifted slightly between each field, while the interference is in the same phase on every field.

The flicker I was talking about was the colors, not the actual pixels.

Any resolution that's of multiples of 4, should come out clear on an LCD monitor. The reason they don't come out clear is because LCD's have built individual lights for each pixel on it's native resolution. If you make it less then it's native resolution, it tries to use a fraction of a pixel to light up a whole pixel which blurs it out since it can't do that. If you upscale beyond native, it wont be able to display all the pixels.
So on a monitor with 1440x900 native, 360x225 is really the highest low you'll get a crystal clear picture with. Any resolution on an LCD though will get you a more clear picture than an old CRT though, and like AndyUK said, this might have been the intent. However because I already know and appreciate what pixel art looks like off of a blurry CRT, I'd prefer seeing it as clear as possible - on an LCD

I disagree with your idea that CRT's are automatically worse. It's just that making CRTs of very large sizes is very impractical. That's the reason why LCDs are taking over.

For a vintage video game system a CRT TV is better. You get an analog signal from the console which directly drives the CRT in the TV. On an LCD TV the analog signal has to be digitized and upscaled to the native resolution of the screen. While theoretically pixel art could be nicely scaled at multiples of the original resolution by duplicating pixels, the LCD will most likely scale it as a "photograph" (some form of bicubic resizing probably) since movies and TV shows will look better that way.

Also, many systems used non-square pixels, for example the NES, SNES, Sega Master System, Colecovision and Sinclair Spectrum all used 256 pixel wide screens. If you want to display those at their proper aspect ratios you have to resize the picture.

Oh don't get me wrong, I'm not directly disagreeing with you. I will play an older game on a CRT without complaint, I'm just voicing an opinion here.
However, in response to the upscale, you're right with regards to TV's which might have all this scaling stuff automatic, however if we're talking about using a computer LCD monitor (remember, if you own a console and the game, it's legal to possess the roms), then depending on your video card settings, you'll likely have a better picture on the LCD monitor. I speak from personal experience though. I've found that my LCD monitor has a generally richer amount of color and clearer picture when I sat it side by side with almost any CRT TV I've used. Maybe I'm lucky, idk.
If we're talking about reliving our past, I will gladly grab an old CRT monitor, pop in an old Genesis with Sonic 3 and Knuckles and enjoy myself.

Ok, so you're saying LCDs are better because you're comparing an LCD computer screen with a CRT TV?

With the same reasoning I can say that CRTs are better because my CRT computer monitor is better than my old Game Boy's greenish LCD

A more sensible comparison would be a CRT computer monitor and a LCD computer monitor.

This is the monitor I use for my retro gaming goodness-

http://www.wellsgardner.com/products/details.asp?iCat=2&iSubCat=47

I have it installed in a MAME cab I built.

I love it,
somehow retro games just aren't the same without that flicker in a dark room.

I really want to build one like that MMF project. Would be super fun.

Though my reason for not being able to is quite obvious. Can't afford it!

I manged to scrounge up the parts over a period of 2 years.

I bought the monitor last.

I built the cab itself with medium density fiber board, and the plans I found online.
If I can find them again I'll post them.

Bought buttons and joysticks here:

I don't remember where I bought the coin slots...

I bought the monitor from the link I've already posted.

I bought the wood at Home Depot.

Aaaand...

I must make one.

Of course, I don't have the expertise of an electrical engineer.

Inside the control panel, the buttons are just wired to a keyboard converter.
