WANTED: Someone to RGB mod my Gamecube component video cable

Looking for someone to RGB mod my gamecube component video cable. This page below shows how to do it (I'd do it myself but i am busy and very horrible at soldering - believe me, I have tried with other projects):

please PM me with a price !

 

Can't you buy a standard RGB cable for the GC?

I think amazon sell them.

Why hack the only way to get component out of the GC?

Ah, Is it progressive scan?

 

Jap and US cube don't output RGB natively as pal one so you need to mod a componant cable to get it. So an european RGB cable would be useless for him.

 

Barc0de explained this to me at one point, and I figure its a good bit of info to pass along:

By default the GC's component output will be in 30hz mode unless the game itself initialized the 60hz progressive-scan capabilities of the system. While many games support this progressive mode, not all do and it isn't activated instantly. You've got to go through the "do you want to enable progressive scan?" start-up option first.

Why is this important?
When modding the cable to be used with a VGA-compatible device (think computer monitor), they require a 60hz signal, 30 won't cut it. This means that you will be flying blind during the enable screen (nothing will show up once the game loads until you press "A" to accept the menu option) and all games that don't support progressive scan will be unplayable.

The same applies for all manner of development hardware, if you want to run a demo of any kind through RGB/VGA then you have to enable progressive scan before you see any output on the screen.

Best of luck!

 

Almost right but you are confusing horizontal refresh rate and the vertical one. HS is alway 60hz in japan and us. However when using game in interlace mode the DAC chip inside the componant cable (once modded) will output 15khz vertical sync signal which (most) computer monitor cannot handle. You need an upscan like xrgb to use that with a monitor.

When game are in progressive mode then the VS is 31khz which is the minimum rate that all pc monitor can handle.

So if the cable is going to be used with a TV them you can leave your game in interlace mode since TV use 15khz VS.If you want to use it on a pc monitor them the game most be in progressive mode.

 

I was confused when he told me and it looks like I'm still a little lost on the subject, but thanks for clearing it up

 

You yourself are confusing horizontal and vertical in half your response! :lol:

BTW, lots of PC monitors can technically display 15 kHz video (CGA mode), but only if the video is progressive.

 

Oups, corrected

 

so can someone mod a cable for me for RGB (with a VGA end on the cable) ?

 

I could make you one depending on what you own now. If you have an Japanese gamecube d-terminal cable them is really easy to do. With a componant cable I will need to replace the whole cable with an VGA one (but those cable are probably cheap to get I think).

PM me the detail if you are interested.

EDIT: Now that I think about it it will be easier to just replace the whole cable with a vga one even with d-terminal cable..

 

Yep you are right barcode mate, if you are doing RGB then the component cable is fine for that, but it's really only useful for interlaced RGb over scart in the uk or europe, or rgb monitors.

If doing a vga cable, then the D cable is much easier to mod for vga.

 

Well whatever I would have to do to get a VGA cable for gamecube. I currently have it hooked up to my VGA/RGB monitor (does 15khz and 31khz) via a VDigi VD-Z3 component to VGA adaptor but it's a bit blurry and not very sharp. I have a compoent video cable but no D-Terminal so ultimately, I want a VGA cable that may also do RGB @ 15khz

 

I have a VGA cable, but I'm not quite ready to get rid of it.

Since the GC doesn't output 240p (at all), just have someone make a VGA cable. It shouldn't be that hard, and it should support 15khz or 31khz. Are there any 15khz only GC games?

I suppose if I upgrade to the Wii I'd get that Wii VGA cable, and sell mine. But, I don't see that happening for a bit.

 

a company in the US has a 15pin vga extension cable for $1.49
you could cut off one end and solder to the gamecube plug

There exist a few Gamecube modchips (qoob, for example) which allow to a.) bootup the system in 480p mode already, and b.) patch "most" games (sometimes even PAL games, sometimes it doesn't work though) to always use progressive video.

Usually, keeping the "B"-button pressed will get you into progressive mode (for non-PAL games. PAL games will instead use EURGB60, which is still interlaced but also 60Hz). The Gamecube-IPL itself is always interlaced, though. But here the modchip helps.

 

No what people are saying is that the D terminal cable is easier to modify, which it is. It is an easier mod than the gamecube component cable.

Those leads look kind of small for a beginner to be soldering. I have no clue as I've never modded one, but how hard is it to gut the component cable (totally) and solder each lead to it's corresponding point? There's no need to cock around with a chip, no?

 

You need to lift a pin on the DAC and connect it to GND (or it's to VCC?, I don't remember, I modded mine long ago) to put the DAC in RGB mode instead of component.

 

Wouldn't the OP want to keep it in Component/VGA mode? He's got a dual-synch monitor, and the majority if not all of his games apparently support 31khz.

EDIT: While we're on the topic, how hard is it to make an Xbox VGA cable (original Xbox)?

 

VGA is just a display standard. Btw, you have an total of four mode for this cable witch you can select using a software "swcith" (the b button while loading) and with the hardware switch (the DAC pin)

so you have:

--Hard-----Soft-

--RGB-----15khz
--RGB-----31khz <=(That what we call VGA)
-CompV---480i
-CompV---480p

So for VGA you put the hard switch to RGB..
