dentro del USBLOADERGX tenes una opcion de forzar PAL sin modificar en si la consola, nunca la use pero si te sirve para el RGB, bienvenido sea.

Igual leyendo un poco mas entiendo que, aunque me tome el RGB con todos esos pasos, lo que sale de la Wii no es RGB puro, si no RGB convertido a YUB pero con un 50% de perdida de chroma para reducir el framebuffer...

O sea, no es RGB de verdad y nunca se va a comparar al RGB sacado de las consolas originales.

Para el que le interese, aqui esta la [spoiler]LARGA EXPLICACION (EN INGLES) -

Ok, I can explain this. But it's going to get technical.
YPbPr Signals
Perhaps I should first explain what a YPbPr signal is, as the page you linked has a rather simplistic view about this. It is indeed right that YPbPr is not the same as a RGB signal, but it's equivalent quality wise.
Unlike composite (or S-Video) signals, that need to use complex encodings to squash the full color space into one (or two) signals, An RGB signal simply transmits the raw RGB colorspace as it's 3 component signals over 3 wires: Red, Green and Blue.
To get white, you mix 100% Red, 100% Green and 100% Blue, which would be simpler to write as RGB(1.0, 1.0, 1.0).
Black is likewise RGB(0.0, 0.0, 0.0) or 0% of each component.
and RGB(1.0, 0.0, 0.0) would be Red.
This is the same colorspace that the SNES (and most consoles other consoles) use internally, and the colorspace which color CRTs need for the final stage of projecting the image onto the screen. Color CRTs have 3 electron guns to display each of the Red, Green and Blue parts of the signal. So it makes total sense to transport the raw RGB signal out of a PAL SNES over the SCART connector into a European TV which can send that raw RGB signal directly into the electron guns. This saves a number of conversion steps, which would inherently cause some degree of quality loss, especially in analog.
In today's RGB centric world, you might be asking, what other colorspaces could possibly exist?
The YUV Colorspace the most relevant to our discussion. It's more or less just a "twist" of the RGB colorspace, Instead of having Red, Blue and Green channels, you have a Luminance (Luma, or Brightness) channel (the Y channel) and two Chrominance (Chroma, or Color) channels (U and V). If you displayed just the Luma (Y) channel on it's own, you would have a perfect black and white image (this is in fact how color and black and white TVs could work off the same signals during the switch-over period in the '50s and '60s, the black and white TVs only showed the Luma channel).
The Chroma channels then provide color difference signals, that tell you how "different" the actual color is from the Gray on the Luma channel. There are two: U tells you how blue or yellow the color is while V tells you how red or cyan the color is.
You can convert directly between RGB and YUV with the power of math, and if you are using enough precision, this conversion is mathematically lossless, you can convert back and fowards between RGB and YUV without losing any quality.
To get Y, you add the R G and B channels together, except we do them in a special ratio.
Y = (0.299 * R) + (0.587 * G) + (0.144 * B)
Notice that Green has the most influence over the Luminescence, while Blue has the least. These constants are ultimately arbitrary, they have been chosen and standardized to best match how human eyes perceive the brightness of RGB colorspace. Green really dominates our perception of brightness, while blue hardly effects it.. Wikipedia describes the math and motivation behind it in more detail. Though do note that those three constants add to exactly 1. We can then do the same kind of thing to get the UV channels.
U = (-0.14713 * R) + (-0.28886 * G) + (0.436 * B)
V = (0.615 * R) + (-0.51499 * G) + (-0.10001 * B)
You might notice that these equations include negatives, because the U channel actually swings from -0.436 to +0.436 and the V channel swings from -0.615 to +0.615.
So:
White or RGB(1.0, 1.0, 1.0) becomes YUV(1.0, 0.0, 0.0)
Black or RGB(0.0, 0.0, 0.0) becomes YUV(0.0, 0.0, 0.0)
Red or RGB(1.0, 0.0, 0.0) becomes YUV(0.299, -0.14713, 0.615)
Green or RGB(0.0, 1.0, 0.0) becomes YUV(0.587, -0.28886, -0.51499)
Notice how green has more luminance than red, as you will observe in real life, solid green is much brighter than solid red or blue.
The great thing about this color space, is it better represents how our eyes perceive things. And it splits up the luminance channel, which humans are really good at seeing from the colors, which we don't notice as much if they are slightly wrong. A common image compression technique is to keep luminance channel at 100% resolution, but throw away 50% or even 75% of the resolution in the chroma channels.
But if you keep the full chroma channels, you can losslessly convert back to RGB using the following formulas:
R = (1.0 * Y) + (0.0 * U) + (1.13983 * V)
G = (1.0 * Y) + (-0.39465 * U) + (-0.58060 * V)
B = (1.0 * Y) + (2.03211 * U) + (0.0 * V)
You might want to try a few example values to see that RGB colors do actually fully round-trip through these equations.
So back to the YPbPr signal, it's the same as RGB, except it transmits YUV components instead of RGB components. Y = Y, Pb = U and Pr = V.
Technically, it is possible to mod a Wii to output RGB color, but this involves adding extra hardware to convert from digital YUV to analog RGB, replacing the existing digital YUV to analog YPbPr conversion. But when you consider the rest of your proposed pipeline there is zero gain to this approach. You have a RGB to YPbPr converter just so you can plug it into your TV, and then your TV will convert that signal back to the RGB colorspace internally just so it can display it.
Best case, is zero quality gain, zero quality loss, but the worst case is you lose some amount of quality at each of these conversion steps. You would be much better off using the stock Wii YPbPr cable and plugging directly into your TV, skipping two conversion steps, though you also might argue that modding your TV to accept raw RGB colors like a European TV would skip two different conversion steps.
But the stock Wii YPbPr will give you the highest possible quality out of the Wii.
But how does the Wii Quality compare to the SNES RGB quality.
I can write an entire second essay here about how the Wii and Gamecube (they are mostly the same hardware) actually process color internally. But to simplify things, the Wii/Gamecube convert from a RGB framebuffer to a YUV framebuffer as the last step before scanning out the image, which as I've said above would be a lossless conversion.
But the Wii/Gamecube actually throws away 50% of the chroma resolution, to get a smaller framebuffer. Essentially, you get a maximum of 720x486 pixel Luma resolution (outputting to a NTSC tv, 720x576 for PAL), but only a 360x486 pixel chroma resolution. This is no big deal, as you can hardly see the difference on the highest quality cables (YPrPb for Wii, RGB for the Gamecube) and it will be completely invisible on the standard composite cables that most people used. But one consequence is, the RGB cable for the gamecube (and the mostly theoretical mod for the Wii) is at the same resolution and doesn't gain any extra quality.
Now this color resolution is actually greater than the most common SNES resolution, which is 256x224 pixels. But the SNES actually has a 512x244 and 512x448 modes. Now when the composite cable was plugged in there was no way you would get that much resolution on the color channels. But with the RGB mod and a game which used that resolution, yes it would be possible to get 512 unique colors across a line, which the Wii is not really capable of reproducing. But finding a game that uses the 512x244 mode is hard. Apparently a few games use it for the menu or character selection screens, but a quick google leads to no games using it for gameplay.
I hope this helps you understand the answer to your question, which is far from a simple yes/no.

Vuelvo a preguntar? Vos no tenes WiiU? O la estoy flasheando? Porque tranquilamente podes tener una "Wii por HDMI" mediante la U

[Console Wars]

No la tengo mas a la Wii U (kind of).

Igual el tema era por aprovechar mi tele de tubo con SCART, ya que el sega se ve de lujo ahi.

Si conseguia emular SNES, Genesis y demas consolas en esa calidad, hubiera sido un golazo de arco a arco.

Pero bue, todo no se puede...

PD: Y Wii (U) por HDMI no se veria feito? Digo, a menos que me consiga una tele de tubo con HDMI, todos las pantallas de plasma/lcd/led se ven feas con consolas viejas...

A mi al menos la Wii se me ve bastante fea por YUV en el monitor de mi compu...

[Magnus87]

Si eso es verdad, se ve un poquito mal en LCD. Como esta avanzando la Scene para WiiU, no dudo que pronto tendremos ports de los emus para Wii en WiiU


Habra que esperar. Tendras que conformarte por Componente

Donde consigo la serie de Los Caballeros del Zodiaco, Saint Seiya en calidad digna y español latino?

Mira, es un tema encontrarlo, busca torrent a ver que encontras, porque siempre es el mismo problema, o se ve como el ojete en latino o se ve bien pero esta en "Español España" y no da XD.

Ahi la podes ver en latino :3

Gracias! Voy a seguir tus recomendaciones.
Pucha! Debe usar flash la página esa porque no se ve en el iPhone. Después voy a probar desde una Pc.

[sakichanes]

Anoche vino un amigo y prendi la wii despues de mucho (porque me mudé y blabla).

Nunca probé los emus de nes y snes de a 2 players, andaban, pero tenian delay de respuesta, es menos de un segundo, pero jode muchísimo.
Al rato probe de a 1 solo player, y también tenia delay, un poco menos, pero es imposible jugar cosas como megaman.

Tienen idea a que se puede deber? En la config del de Nes probé otras opciones de video y esas cosas, pero en todas hace lo mismo. La de snes no me puse a tocar, ya estaba hinchado las bolas.

[Arino CX]

Saki yo nunca tuve un problema con esos emus y los uso todos los dias, lo unico que se me ocurre es que estes usando unos emuladores que no funcionan bien. estos
