The video shows XBOX, then FAMICOM, then XBOX again.

The only issue for my technique, is that, since I need to use
638 of width in my MednafenX-Nes screen, little parts of the image
are cropped out --- but they are "dead zone" and do not bring
any damage to the "hot game area."

Why I stick to 638 fo width? When you turn of FLICKER,
put hardware filtering in POINT and turn off soft display,
you can EASILY notice damages graphics created by a
un-correct aspect ratio. Example of this can be seen on
the SNAKE MAN LEVEL on MEGAMAN3. Pay attention
on the background while you move around.

And please remember, if you are fan of graphic filter enhancements,
like eagle, hqx, 2xSai, and so on, this topic is not for you... (c:
Kindly speaking, of course.

And I use a traditional CRT televison screen, flatron LG,
with the xbox on the most basic screen output configuration.
And with AV Cables!

This is something I've always wanted to do but my old consoles died long ago.

But when watching this video it appears that the cropping is at an unacceptable level. For example, you can't see the first letter in the word SCORE in the upper left-hand corner. If the correct aspect ratio is the key to getting point filtering looking right then it should be possible to reduce the display size as long as the ratio is maintained and not lose noticeable parts of the screen.

BTW, after playing with different emulators I noticed that getting a similar look to this on XSNES9X isn't possible since you can't disable software filtering. Setting the option to None just gives you Simple2x. (thanks lantus   )

I think the problem with reducing the size is that it's not possible to match each pixel line from the emu to a scanline on your tv.

I'll have to do some more fiddling around with this.

If anybody is interested here´s the complete documentation of the conexant video encoder: Conexant

I took a look, and though it says it supports 320x200/240 I think maybe is not what we want as the resolution charts info shows 320x240 Pixel double set. I´m not sure about what it means.

Anyway, I think there´s is an alternative hardware solution.

1.- Set the screen size to 2x the original console resolution
2.- Set Xbox resolution to 640x480p
3.- Use a hardware scan divider so the 31khz refresh is divided into 15khz by descarting half of the information, and then resulting in 640x240p which in case or using point filtering would output exactly the same video output as the original console (even real scanlines )

The problem, is, I have no idea about how to build an scan divider. But I´m pretty sure it is possible.

Another problem is, all this theory would be pretty easy for us european people, as most tv´s are able to input R G B and sync signals each one independent, but USA standarts´s, svhs, component video,etc would need an additional converter from rgb to those formats.
