    So I've been interested for a while in getting my PAL GC to output directly to my monitor (VGA)... Decided to do a bit of reading, and places say to use the component cable or d-terminal cable, both appear to work fine with PAL consoles but a few places sell (or sold and no longer have stock) of gamecube digital -> VGA cables and they say 'NOT compatible with PAL consoles'.

    So am I right in believing I would need to get a composite cable and an NTSC console or could I just get the composite cable and solder the extra wires (and resistor) to the DAC and it'd output to a VGA monitor fine?

    Any help on this would be appreciated!

    No progressive signal can be transmitted via the standard connector. Also, both the component and d-terminal cables have a special chip inside them which the composite cable will lack. You will need such a cable to source audio, though, if you do get one or other of the progress scan cables.

    I really don't know why I put composite cable! XD I meant component cable. I read that the D-Terminal cable outputted a composite signal so was thinking it was a bad idea.

    So, would a component cable changed for VGA work on a PAL gamecube or would I need to source an NTSC model?

    you can do a VGA mod with the component cable but you are not able to see any 56K signals, like the NGC boot screen...
    but you can also buy a tv card so you can connect the gamecube to the computer with the composite cables or buy a signal converter wich is probably the easiest to do, but they are very expensive (tv card and/or signal converter) (around €60,-~€70,- here in Holland)

    I have a TV card and I hate it, it's not smooth at all, the '240FPS' rubbish is just a lie.
    Does the VGA mod work with PAL consoles though or would I need an NTSC?

    You need a transcoder. The one I uses takes CV & YC inputs and transcodes to VGA SVGA XGA WXGA. Look into Kramer Tools.

    So you're saying I need a transcoder when there's loads of site saying converting a component cable to a VGA cable just requires a resistor and a few wires...?

    A transcoder is unnecessary.

    For progressive scan you need a Cube with the digital port out back and games that support progressive scan (i.e. NTSC rather than PAL).

    So would a PAL cube running games via starcube (from a PAL disc) work? Or would I need an NTSC cube and have to hold down some buttons when it turned on?

    I don't know what starcube is but if it's like Freeloader then yeah, it should work. It's the games that need to support progressive scan, assuming you're running non-PAL games and have the requisite hardware then you should be set.

    Starcube streams games over the BBA.
    Boot up starcube loader from modchip with legit PAL disc in drive and then stream a game over ethernet and it works... Humm might just go for the cable then!

    I remember that BBA thing now. I think it used to required a buffer overflow exploit in a Phantasy Star Online save game... something like that.

    Let me know how the cable goes if you do end up going for it.

    For anyone that's interested, I'm going the cheapskate way of getting two video-sync seperator ICs and going to see if I can interface either of them with the composite video signal that the PAL gamecubes have and mangle it about with the standard RGB (non-digital port) out!

    Should have some 220uF electrolytic capacitors

    Could it be that someone swapped it with an SNES cable? I know you have to remove some capacitors from the GC RGB-cable to make it an SNES-RGB-cable. Otherwise the picture you get from the SNES is way too dark.

    If your monitor handles 15khz then a sync seperator might work.
    If not then you'll at least need a scandoubler, which takes one line of 15khz video and converts it to two lines of 31khz. You might be able to find a schematic for one online.

    Something like this will work out of the box:

    It won't look as good as using a hacked cable, although there aren't that many pal games that support it. The number of NTSC games which support it isn't that much bigger.

    Yeah my monitor takes 15KHz, my NAOMI2 systems works fine on it directly :)
