i love this thread and the idea behind it!

Are you sure they work? Could be faulty ones or the infamous bad batch that stop reading the disc when they reach a certain temperature (I bought a new Gundam special edition on eBay that had this problem - I'd already left feedback by the time I found out, but the seller probably didn't know either.)megalomaniac wrote:good news, the "non-working" gamecubes arrived...
bad news, they all work...

No, the Wii Component cable is just a piece with some wires. The Gamecube cable does digital to analog conversion, which requires this special chip (and circuit).M tha MaN wrote:Just out of curiosity:
Wouldn't it be easier/cheaper to make just an adapter so that the Wii Component cable fits in the GC ?
Actually there's a digital signal bus that can be tapped into on any GameCube; you don't need a revision A cube to have component.Benni wrote:I´m also interested!
BUT - I there is no digital out on my GC!
First I need a way to get a digital out!

I've been thinking about making a brief post on the GC's video outputs. But now I'm thinking that a larger, more-encompassing thread would be pretty useful. I haven't seen a lot of focus on the matter and I think there's a lot of interest out there in it.

did anybody ever try a transplant??Ashen wrote:PAL boards DO have different A/V chips than NTSC boards, which is why we fight to get Luigi's Mansion ntsc to work with the Wiikey. The PAL version boots, but the video is handled incorrectly by the NTSC A/V chip. :/

the AVE chip is the same in both DOL-001 and DOL-101..
It certainly does appear possible to solder leads to the AVE chip to allow those without a digital port to wire up a MX chip...
I have not had the time to try this on a DOL-101, and i also wondered if it was even going to work because of possible IPL issues not allowing 480p...
just like the PAL GC does not output S-Video and the NTSC GC does not output RGB...could this be controlled by the IPL or do PAL GC's have a different AVE chip?
I havnt done enough research on it yet, but i have been looking for a PAL GC to maybe help me draw some conclusions
here is the data i had put together so far..
the AVE chip contains all the pin connections required for the MX B012355 board except for 12V and 54MHz..
- 12v is only required for the D-Terminal Cable. The voltage is reduced on the MX board to provide a reduced 5v data signal to trigger this type of TV to display video as interlaced or progressive...
- 54MHz was traced back to the MX RTC chip and should be a suitable solution..
i would be interested to know how Tchay cut his board for the Envision to determine if the filters were removed..
if so, then this would make conversion easier......as long as the IPL doesnt provide an issue..
i imagine some of the Resistor and Capacitors i have listed below should be for S- video and PAL RGB, maybe someone can help fill in the gaps
There may be different revisions of the A/V chips, just as there are different revisions of the MX chip, but the hardware is essentially the same. They simply operate in different modes, which is software dependent. This is why the transplant mod mentioned above didn't work, because the new chip was being told to do the same thing as the old one.Ashen wrote:PAL boards DO have different A/V chips than NTSC boards, which is why we fight to get Luigi's Mansion ntsc to work with the Wiikey.

i was looking for pinouts also but could not find any...Durgan wrote: Nice! I hadn't been able to find those pinouts yet. Where did you get them? I'll be sure to include this info in the thread I'm making.

I don't think imposing limitations on progressive display would be in the IPL's job description, but there might be registers elsewhere that prevent it. Interlaced display would certainly still be possible though, and I would guess progressive would (at least on NTSC cubes) but I don't know for sure. PAL GCs should have the same AVE chip as all the others, I'll go into this more as a response to both you and Ashen.

I'm writing up a more in-depth explanation of all of this right now. Unfortunately I may have to leave before I finish and complete this when I come back in a day or two.
if this is strictly hardware, then perhaps zenloc may have had better testing results after a hardware only transplant..Ashen wrote:I have no doubt there are different revisions of the A/V chip. That doesn't have anything to do with the fact that PAL and NTSC A/V chips are different though. I know this for fact, not just theory. PAL chips output RGB natively, NTSC chips output s-video. It has nothing to do with software. Its a hardware thing. The chips are also labeled differently. NTSC chips are AVE N-DOL, PAL chips are AVE E-DOL.

Zenloc wrote:The wiikey does not support forcing video mode unlike the wode which does. The av chip of a ntsc board does not support pal composite signals that's why the image doesn't look right nor does the resolution. It's the same on pal boards altough they do show the right colours with a ntsc signal. The resolution however will be 480 cropped in a 576 resolution giving you a big black bar on the bottem of the screen and squishing the image.
switching av chip won't work I alreadt tried that. Nor does it work with switching any other components. I tried swapping the av chip and both clock chips and nothing give you proper pal and ntsc signals on one board.
Any of you have other idea's??

The only uncertainty was specifically noted. The rest of what I'm saying is each from different sources I have bookmarked from across the net (I can give specifics on stuff if you want). The best explanation I've found about the DAC's modes is in patent information for the GC, here, page 86, line 10. You can find a list of other various GC patents in the references section of this document: http://zelda64rus.ucoz.ru/_fr/1/yagcd.pdf (which itself also has a lot of good information).megalomaniac wrote: please do not get discouraged by the following....
but i question where you data comes from...i assume this is just a theory since you state "its possible" and you "guess"
also you indicate the AV chips operate in different modes due to software..what software?? the game title or the IPL?
im most certain Zenloc tried both NTSC and PAL versions of Luigi Mansion as per proper testing of his transplant...
The chips receive information alongside the timing signals of the YCbCr video stream for what it should be converting the video to (it's sent on the CbCr data lines during the vertical blanking period). So what the DAC outputs is actually dependent on variables "keys" that the GPU lays out. [Check out the link and page I linked to above on the patent info.] The part of the GPU that handles its own video output (and finishes creation of the signal) is called the video interface. It too is capable of operating in different modes. Also look on page 87 of that same patent doc, just before the table. The variables that describe the mode are called "registers" (for some reason it doesn't explain it there, but "VI" stands for "video interface"). Where the "registers" are stored, however, or how to change them, I do no know. Have you been able to find any other specific information about these chips?Ashen wrote:I have no doubt there are different revisions of the A/V chip.
