SNES (Super Nintendo) RGB Cable (for North American NTSC)

You couldn't find a proper panel mount jack? That's not going to hold up very long with that hot glue.

Yeah, it wiggles. I'm not keeping it that way. I didn't have any panel mount jacks on hand and didn't want to wait until more came in.

Sorry, these are not my pics. I found them on the net and it is the same cable as mine. I will take new, better photos when i get home tonight.

Remove the resistor array (the long black 5 pin component in your second picture), then cut the traces on the PCB for R, G and B and solder 3 220uf electrolytic capacitors in place of the cut traces for R, G and B with the + side of the caps connecting to the console side of the PCB.

If you have any sync problems after modding the cable then put a 75 ohm resistor between sync and ground but I doubt you would need to if you are using it on the mini because the mini has a sync level adjustment option anyway.

Thanks, i'll have a friend look into this.

I've got a weird issue with my SNES RGB setup. I'm still somewhat new to this so forgive me.

I have a Panasonic Plasma and a CSY-2100 clone. I ordered a SNES SCART cable from retro_console_accessories on ebay and using this setup I'm seeing a small amount of distortion in the top 5% or so of my screen:



It doesn't look like much, but when the screen is scrolling it's very noticeable. So I did some testing:

The problem doesn't exist on my Philips CRT. I've tested three Model 1 SNES including SHCV-CPU-01, SNS-CPU-RGB-02, and my new SNS-CPU-1CHIP-03 and on the Plasma it shows up identically on all three. Sometimes the screen will flicker and the curve goes away.

I also had Specialty-AV send me another CSY-2100 and it had the same problem.

So I bought a Genesis cable from the same seller (though I still need to sort that out cause I didn't get what I thought I was ordering) and the Genesis doesn't exhibit the curve at the top of the screen.

I've also flipped/mirrored the screen to help verify that it's the input that's the problem.

So my questions are:

Does anyone know what's going on and/or how to fix it?

How can I tell if my 1chip-03 is outputting csync? The image acts pretty much the same as the other revisions and I thought if it isn't syncing it would be pretty obvious.

Thanks in advance.

I had the same problem with a CSY-2100 (original, not a clone). Didn't show on a CRT, but did on processors and on HDTVs. Which clone do you have ? Do you have a link ?

I'm planning on getting a Saturn cable soon and one day I'll probably do the NESRGB, but something tells me it'll only be the SNES that does it.

[Fudoh]

interesting idea. I can't really remember. I eventually fixed it by getting a Kramer transcoder instead. But if you happen to get a Saturn cable, please update us with the results.

Einzelherz: I also had the same problem with my HDTV before getting a XRGB-Mini. Hitting the reset button a few times did the trick for me.

You mean hitting reset cleared the problem before you bought the XRGB?

Exactly. After resetting the SNES a few times it usually solved the issue.

Hey all,

I have read through all the posts here and this seems like a good place to ask. I have a SNES Mini, and I attached csync to pin 3 of the multi out. I have ordered this cable http://www.ebay.com/itm/251499304153?ss ... 1439.l2649 as it was a good deal to use with my XRGB Mini that's on it's way. I also have the adapter to take scart and make it into JP21 for the XRGB so no worries there. I am just curious if someone knows what the official nintendo European scart cables used for sync and if I will have to mod the cable. I'd prefer to use composite sync then composite video sync.

They all use composite video for sync, you don't need pure composite sync on the mini.

Though it's much better to use composite sync, when you use composite video for sync on the SNES mini you'll get "crosshatching" artifacts on certain colors (especially on yellows and oranges).

I found another cable for another system that causes the same top curve on my CSY-2100 clone. It's a Naki Dreamcast scart cable (it was $5, couldn't resist). Have any of you guys that mentioned problems with your SNES and the curve tried a Dreamcast on your CSY?

Update: I started playing around with the Dreamcast 240p test suite (http://junkerhq.net/xrgb/index.php/240p_test_suite) and I noticed something. In the test suite switching between 240p mode and "fake 480i" causes the curve to disappear and reappear.

So in 240p, it's present. In "fake 480i" (not really sure why it's called fake) it is not.

Interesting to note, in 240p mode, the screen is clipped on the bottom, but not so in fake 480i.

Yay, more testing!

Dreamcast Street Fighter III Third Strike has the ability to run 240p or 480i. In 240p, I get the curve. In 480i, I don't. That doesn't really explain why the SNES curves and the Genesis/SMS don't.
