Hello, I have a SNES with a S-RGB chip (S 9637 BA) can i mod this to have RCA RGB output? can i come right off of the multi out pins? I found a couple very helpful websites but with some mixed info i am a bit confused and i seen a few threads with successful mods with different chips so i figured i would get some experience help from here. Any info is appreciated. Thank you SNES ,S-RGB,RGB,chip ,S 9637 BA, 9637,MOD
You can get RGB with an RGB SCART cable so there is no need to mod the console. Now if you mean YPbPr Component video, that is not RGB and it requires an RGB to Component converter. You can either got one that is installed inside of the SNES or you can get one that connects externally via an RGB SCART cable. If you do mean RGB and you want to mod the console, it depends on your region. NTSC SNES consoles need 4 RCA jacks: 3 for Red, Green, and Blue, and one for sync. You can use Composite video as sync, Luma as sync, or C-Sync. All of these signals are on the Multi-Out and can be tapped from there. You will need to put a 220uf capacitor each of the RGB lines. Sync does not need anything on it. PAL SNES consoles need 75 ohm resistors tied to ground on each of the RGB lines. C-Sync is not available on the PAL SNES Multi-Out so you will have to use Composite video as sync or Luma as sync. Either one requires a 75 ohm resistor tied to ground. Hope this helps!
thanks for your help, I am in US. Would it be possible to run RGB rca jacks without the sync? I have a RGB cable to VGA. Let me tell you where i am. I drilled holes for 5 RCA jacks, RGB L R, 2 were going to be for audio. but if i have to run sync is suppose i could make it mono. was i better off putting a solder point VGA female? I have 220uf Capacitors in series for each line. maybe i am better off turning it to component. are there specific instructions for that?
You need a sync signal, even if uses vga... But does your device support 15khz RGB via its vga connector? Just getting a random ebay cable doesn't mean it will work (there are some really odd cables on ebay that I have no idea where you could ever use them)
That VGA cable you have is designed for PC Video cards that output YPbPr Component Video over a VGA connector. In order to use the SNES on a VGA monitor, you need a 15KHz RGBS to 31KHz VGA (RGBHV) converter. To do component, you need a RGB SCART to Component converter and an NTSC SNES RGB SCART cable. You would then need a SCART audio extractor. If you want to use the jacks you already installed, you can buy a SNES RGB to Component converter mod board that is small enough to fit in the console. Post a WTB in the WTB forum in the marketplace if you want one. I'm sure someone can send you one.
There are monitors that accept 15khz RGB over a hd15 connector. Can't just issue blanket statements (though you are probably right that his device doesn't and needs a converter)
I know there are monitors out there that support it. The Commodore 1084 supports it and there are other ones out there like some of the Samsung Syncmaster monitors. It's quite rare and I wish it was supported on more devices. How hard would it be to make a 15KHz to 31KHz converter?
thank you for all the great info, at this point, I think i would like to try to do an internal component output using jacks I have installed.. I have a 1995 SNS-CPU-CHIP-02 what would be the easiest / best way to do this?
If you want to output component then I would get this board. http://etim.net.au/shop/shop.php?crn=207&rn=550&action=show_detail
Would Tim's board work on the SNES? It's missing the 220uf capacitors so you will need to add those to the RGB lines before they go to that board.
Most snes's can be modded to have component without the need to convert from rgb, both me and pikon have modded systems with this. Mine is a snes whilst pikon's is a super famicom. Click here
How would I know for sure? my encoder chip says "S-RGB Nintendo S 9637 BA" I looked at the threads pictures and the layout is different as well as the chip, yours is 93, mine is 95, did they do away with the supporting chip? Everyone else, thank you. That chip looks perfect if I cant do it another way! Thanks!
