NTSC SNES Scart problem

I live in the UK and recently bought an NTSC SNES.

It came with a scart lead but I have had no luck getting a signal to my TV through it.

At present I'm using the ariel lead from a PAL SNES instead, which works ok but would like to understand why the scart lead isn't working.

Also, as a side note...the console came with an adapter that lets you play PAL games on the NTSC SNES. It's been modified to let an NTSC cart slide horizontally in the back while the PAL cart fits vertically in the top.

I didn't know this could be done, but it works great!

 

Your scart lead is home made or is an official PAL cable ?

 

As far as I can tell it's the official scart lead that would have come with the console. At the pin end it had a small flick switch the purpose of which I'm unsure.

 

Hum... Strange NTSC SNES has no scart connector lead. Can you take a pic ?

 

Oh right, I thought NTSC SNES used scart - my mistake. I wonder why it came with a scart lead then. I've asked the person I bought it off if they have used the scart lead with it.

I'll see if I get a reply. I'll take some pics too.

 

It sounds like the SNES has had a PAL conversion, as you state you are using the SNES with RF lead, it could be that the SNES has the RGB lines rerouted so it could output a PAL signal. If you have a Nintendo AV lead (the one with the Red, Yellow and White leads) then try that and see if you get a picture.

 

All early NTSC Snes have RGB output capabilities. But only PAL version is bundled with a RGB scart lead. However this cable don't works with NTSC SNES. It's modified, because PAL SNES uses a slightly diferent RGB signal (I don't know why, but PAL SNES RGB lines uses a strongest signal than NTSC ones).

But, if you would use RGB on your SNES, you can use a Gamecube scart lead, it's works fine.

Last thing, if you live in UK you must take care to SNES psu. If you use the original psu with a 240 to 110 step down converter no problem. But if your plan it's to use a PAL snes psu don't plug it into your NTSC SNES. PAL SNES use 9v AC, NTSC SNES use DC.

 

very interesting. why the hell would they use DC on the NTSC model? I m sure there's an interesting legality hidden somewhere in there if not a good technical reason

 

PAL SNES dont have RGB cable bundeled. Its only an scart adapter for the Video/Audio chinchs.
You musst dissarm the elcos in the RGB cable. Than you can use RGB cable from cube and n64 for NTSC and PAL. I use my RGB NTSC N64, PAL SNES and NTSC/US SNES with one RGB cable.
Also an ntsc power supply works with an second PAL Unit, but how long?;-)

The PAL unit use: 9V ~1,3A NES-002E with 9-9,4V ~ 1,3A Output.

The NTSC unit use: 10V ~850mA SNS-002 with 10V ~ 850mA Output.

Some guys use an MD power supply for her NTSC SNES.

 

You are wrong. Maybe in Germany SCART is not common. But in France all PAL SNES are bundled with a RGB SCART lead. Same thing for Genesis, Master System, Dreamcast, Saturn and many others machines of eighties and nineties era... In France, the first manufacturer who do not put a RGB cable in package is Sony. Since early 80's all machines have a RGB cable. For example all Nec Coregrafx \ SuperGrafx are modified to ouput RGB out of the box.

Same thing for NES\Famicom. euro NES uses AC, Famicom and US NES use DC. In my mind, it's for economics reasons. Nintendo kept the same psu provider. NES and SNES use the same psu...

 

Thankfully the french did something right or SECAM consoles would have been 20euros more expensive fo a PAL to SECAM convertor.

 

In fact, the latest SNES were bundled with crappy RCA cables in France.

 

PAL snes had just composite + composite to scart adaptors.

in no way rgb scarts at least in 99% of europe. Can't tell about france...

 

Many thanks, I've got a Gamecube scart somewhere so will try that!

 

I persevered with the scart lead that was included with the SNES and it does work. I just had to select chanel EXT1 on my TV. All the little switch on the lead does is make the picture on screen have a red tint or not.

It's odd that this lead works with an NTSC SNES so Jamtex may be correct in saying it is converted to PAL. It came with a big 3-pinned PSU too that enables it to run from the UK mains.

Great to see Super Mario World full screen, 15% faster and with a super crisp image through the scart lead.

 

From what I read, NTSC Super Famicom and Super Nintendo systems output RGB slightly different than PAL systems. However the NTSC Super systems RGB output apparently is the same as PAL GameCubes. So the proper RGB cable to use with a NTSC Super NES/Famicom is a PAL GameCube RGB cable which is what I use. It works great. I think you need some resistors in the cable and maybe something else for the NTSC SNES and PAL GameCube systems where as PAL SNES did not need these.

I'm not sure what you are talking about with a conversion to PAL. The NTSC SNES is in a completely different plastic case than the PAL SNES.

Good that you got it working though. RGB is so much better than using Composite or S-Video.

 

I feel some heating against SECAM standard. I already read this in another topic... Are you jealous of the french touch TV stadard ? :110:

You are right. It's when N64 and SNES has been sold at the same time.

I never said that. But for France, yes all 80's, 90's consoles has been bundled with RGB SCART. For example Colecovision have RGB scart lead, Atari 2600 (no on early versions), Jaguar, Genesis, Master System, and even the NES with a "crapy" builtin composite to RGB converter.

No standard business in RGB.

 

Indeed, this is true if you're using a Super Famicom in the UK, as the adapters fit each other and therefore care must be taken to ensure the correct adapter is used with the right machine (DC for SFC, AC for UK SNES).
With the American design SNES, it has a different adapter socket all together, so you have to either use it on step-down (with the original adapter), or purchase a proper UK adapter with the correct plug on it (it has a rather strange large pin type connector).

For RGB the American design SNES will not auto-switch when used with an RGB SCART lead (for PAL SNES consoles) as the switching voltage is on a different pin. You have to manually change the A/V channel on the TV.
In some cases when using a Gamecube SCART you have to remove the capacitors on the RGB lines, otherwise you get a dark picture.

 

PAL NES and US NES have the same psu. So it's kinda odd US SNES switched to DC 'suddenly'.
Next to that, I'm pretty sure French SNES' came with the rca cable, and the RGB cable was only sold seperately. Not 100% certain though, but then I'd love to see some pics of a boxed French SNES with RGB cable!

 

Why on earth do you keep bumping old threads? First NFG Games, now here...
