Huh. That's pretty odd. Component is simply RGB converted to YUV, which UV are then merged into C (S-Video), and then C is merged into Y to create composite. If it had composite or YC output, why not output YUV as well? It surely must be generating YUV at some point during encoding to create S-Video or composite. I figure it's 'cause they used off-the-shelf parts that didn't support it, but it's still bad and nonsensical design.

Because Nintendo are dolts.

You should see how difficult it is to get RGB out of the Nintendo 64.

[Shadow Hog]

Yeah, really. I want a Jungle Green N64, and I want an N64 that can be modded for RGB, but these two are not one and the same - only earlier motherboard revisions of the N64 support RGB with some modding, not any of the later ones, including the Jungle Green ones I want.

Not that I use anything better than S-Video right now, but y'know, options.

Do GC component cables output higher resolutions ? If so then that explains why the internal DACs are not used to make the component signal.

It allows for 31.47 kHz (aka "480p"), in addition to 15.6/15.734 kHz.

The only reason they insisted on a second cable was because there wouldn't be any way for the system to tell if a component cable was connected to the regular AV port, since it doesn't have any mode sense pins. It's a rather stupid reason to add a whole other video port that requires an external DAC though, especially since they could have just added an extra 'pin' somewhere else in the connector, similar to USB 3.0.

Addendum: On the Wii's AV port, the "RGB" lines are mapped directly to "YPbPr" when a component cable is connected, rather than using the logical order of mapping Y to G, Pb to B, and Pr to R. No idea why.

[TmEE]

The internal DACs most probably cannot handle 12MHz bandwidth needed for "480p". 15KHz needs only ~6MHz of bandwidth on the DAC. You can push higher rates but there's gonna be severe horizontal blurring.

Y is on Green because it there is Sync on Green connection and Y is probably only of the 3 DACs that can do sync insertion. In SCART RGB connection sync comes from the composhit signal though...

You misread the addendum. Y *should* be on Green. On the Wii, it's actually on Red.

Pin 3: Composite (PAL/NTSC; disabled when using component)
Pin 7: Red (PAL), Y (NTSC S-Video), Y (component)
Pin 9: Green (PAL), C (NTSC S-Video), Pb (component)
Pin 11: Blue (PAL), Pr (component)

Whoops... yeah, it makes no sense anymore haha.

I have an actual cable for the Gamecube, and in fact have sort of been waiting for it to reach $200 or so so I can make a mint off of it. :p

Also, I dunno how good an idea it is to rely on your roommate for a TV. Most of mine never had a TV and I was the only one with one.

Finally, my original Gamecube's drive is dying, so sadly I don't get any real use out of my cable anymore.

I theoretically could bring my TV, but I don't know how much my roommate or any friends would appreciate me bringing a 20 in full screen CRT to college. But it does have a built in DVD player!

Has anyone ever tried modding a GameCube to use Wii Component cables or something like that? What are the problems that could occur when doing that, besides it probably being a waste to begin with (taking apart two consoles just for one little thing).

[winterhell]

Gamecube's output needs an active conversion to component, thats why the original cable is so expensive. I don't think there is a solution that costs less than the console itself.

[SpeedStarTMQ]

There ain't. I explored that avenue. Having to buy a cable 4 times the current cost of my GameCube was fucking stupid, but I'm glad I did it. Couldn't put up with that shitty quality any more, plus when I one day no longer use my Wii, I'll need component picture!

Was also thinking about in the future when I wanna dig my GameCube out and play, because TV's will only get better in picture quality from now on, and in 20 years time I might wanna dig that bad boy out (I still play my Mega Drive!)

[GerbilSoft]

The other option, which is probably cheaper, is getting a used Wii RVL-001 and third-party Wii component cable.

That being said, I also just got a GCN component video cable for $toomuch. Unfortunately, my GCN's audio is still broken, so I either have to fix that or get another DOL-001.

The cheapest is... Dolphin <3

Not only that, but its also making it harder and harder to justify playing at 480p when you can play at 1440p with Antialiasing.
This is different from playing Mega Drive on an emulator though, as you cant render the image even 10% better than the console.
