Saturn RGB Technical help please...

  1. Evening all.

    Bit of a bugger occurred earlier; Bob the Bunny escaped into the front room and decided to chew my white NTSC-J Saturn's RGB Scart lead.

    Not to worry methinks, and off i charge upstairs to retreive the RGB Scart lead from my black PAL Saturn. Strange thing is, the lead works, but not in RGB mode with the Japanese Saturn. The picture is dark and the TV doesn't switch over to RGB mode. Odd thing is, I tested it and the cable works in RGB mode with the PAL Saturn????

    Surely there can't be a difference between PAL/NTSC-J Saturn AV outs? Or is it the cable that's different (can't see why it would be)?

    I just want my nice crisp RGB output back. So anyone know what the problem is? Is it just a new scart lead, or can i modify this one? Heeeeelp please! Cheers.

    .

    from what I remember RGB in NTSC-J is not the same as in PAL territory. Also those RGB cable from 3rd party vendor are different beast altogether.
    Believe your only bet will be getting JPN RGB cable which won't be that easy I'm afraid unless you can get from YJ...

    cheers

    Yoshii Kun, an European Scart lead is different to a Japanese one because their pins doesn't match exactly. That's because you can use a Scart cable from Europe in a Japanese console and vice-versa.

    Since I supposse it'll be complicated to get a Scart cable from Japan or you don't wanna modify your European cable, I recommend you to get one from here: http://www.ravengames.co.uk/leads.htm . They sold European and Japanese Scart cables.

    Good luck, amigo. Salutes ;) .

    PD: Don't kill Bob ;) .

    Obviously if both cables at one time worked, BOTH of them are SCART, even the Japanese one (its not official is it?) This is because the Japanese cable has a different pinout, you wouldn't get a picture on it at all if it were an official Japanese "21-pin RGB."

    Which SCART lead he uses really shouldn't matter, both cables share the same Saturn connector, on the TV end the pinout is different but as far as I know Sega never changed the Saturn-side pinout.

    Despite of that, it sounds like the problem is due to the "switching pin." Apariently (I wouldn't know living in America) +5v is required to switch into RGB mode on many SCART TVs, investigate that.
     
  7. Hmmm.

    Decided to unscrew a DC RGB lead to see what the difference was. Seems a DC needs resistors and stuff to get RGB. All a bit messy.

    Anyways, seems there is a difference in the actual lead. The A/V out on a NTSC-J/PAL Saturn is the same, but the cable differs, apparently. Trying to work out what I need to do to my PAL cable to get it to work in RGB mode with the NTSC-J Saturn now (missus threw old lead out. arggggh).

    So if anyone can help with modding the cable, please tell me what to do....

    These seem to be the key, but its 1:30am, :smt033 and my brain hurts trying to figure it all out.

    Arrrgh, need RadiantSilvergun back in RGB loveliness.... Hellllp

    try here

    Have you tried www.gamesx.com for pinouts? Don´t know, but maybe they can help. As far as I remember, the resistors in the DC cable are there to switch the DCs multi-AV-out to RGB mode, for a Saturn they should be useless. The SCART-connector on japanese tv´s though is not a real SCART-connector iirc, i.e. it is shaped like one but the pinout differs.
