Modding a PAL French N64 for RGB. Also, what cable do I need?

Yes, it does

 

In this page (in french), there are various tests of the mods.

 

None of those are the mod I am talking about, like I have said already.

 

Hey Bad_Ad, did you remember to check your cables yesterday? Can I get confirmation that the PAL snes RGB SCART cable is what I need?

 

My bad, the mod on this page is almost the same as the one you mentionned, except it doesn't use any resistor.
But why is there space for extra chip on the motherboard?

 

I just tried with an original pal snes cable, the image is acceptable , still the THS7374 gave a way better picture on the same tv set...

edit: CORRECTED

 

No, it shouldn't vary at all. Its the exact same mod as the snr jr, using the exact same chip.

I will double check mine later on and let you know.

 

You're using a different mod from what Bad_Ad is recommending though aren't you?

 

None of those mods are using the output from the S-RGB chip. Which is the amp thats built onto french N64's and is exactly the same chip you would be using by placing the parts on the board.

 

You can flame me if you like... :excitement:

I re-checked my n64 since I trust Bad_Ad84 and I discovered in horror that I did not connect the RGB lines from the S-RGB chip but I was still using the non-ampified connection... So I did it correct this time and it works with the PAL SNES RGB cable.
The image is OK but in no way reached the THS7374 I saw... personally I will test with the 7314 amp.

So to recap, getting RGB lines from S-RGB chip via 75ohms resistors work with original pal snes rgb cable. But I think there is room for improvement.
MAYBE because we still use composite for sync, I notice that S-RGB outputs c-sync, Bad_Ad84 have you tried using this instead of composite? I assume it will need a 75ohm resistor like the RGB lines?

 

I use csync from the S-RGB chip, which I did mention in one of the posts in this thread.

composite video for sync gives a crappy picture (on my tv at least), switching to csync improved things a great deal

 

I also tried the rgb cable with the caps, I get a better picture with it, has more vibrant colors... but with composite ofcourse

I forgot about the c-sync part Bad_Ad84 , now I saw your post again... I assume we cut the composite connection to the AV PORT and patch the c-sync on the pin there, correct?

 

"Room for improvement"? In what way? Is the picture still too dark/bright?

Okay, it sounds like the SNES RGB SCART is the cable to use with this mod, but it would be nice if I could get a confirmation on that from someone awesome and knowledgeable before I go to the expense of getting a genuine Nintendo RGB SCART cable

 

Unless you have a cable that you can open the console end and swap it to pin 3 (where csync should be) then yes, you can cut the trace or remove the cap (trace back from the pin and you will see the cap). Then connect csync to it.

I think the difference keropi is seeing is due to using csync when he used the amp and currently using composite for sync. At least thats how it seems to work for me

 

^ I will give it a shot Bad_Ad84 do you remember if I still need a 75ohm resistor or it's a straight connection?

BTW, the amp only takes RGB lines, not composite or c-sync, the only work for it involved the RGB lines and gnd/vcc so it was composite-for-sync all the time...

edit: ok, raised cap from one side and patched c-sync there... I get a sharper image now

edit2: isn't it odd that when I turn to c-sync only and put the scart cable in AV2 socket (that it's not RGB) and I get composite picture? On an LCD tv that is... I thought you don't get a picture with just sync?! or the tv also gets the rgb lines?

 

Just quickly, all official Nintendo SNES SCART cables are RGB right? They didn't make any SCART cables that only outputted in composite? I've manged to find an official SNES SCART cable, but I want to be sure it's what I need Also, are there any places better than eBay to track down these damned things?

 

AFAIK all original Nintendo Scart cables of the snes are RGB (which naturally falls back to composite in monitors that don't support it) , get one from France to be sure

I have installed a switch, one feeds composite and the other c-sync on the monitor... can't say that I see a noticable difference though when I flick it real-time... either I don't get c-sync from the S-RGB pin or it needs a R75 to work better or something... more tests tomorrow

 

hi guys,

i just ordered a N64 (NUS-001(FRA)) and wanted to know that the only thing you need to do is to connect 3 75ohm resistor from S-RGB chip (+ some wires) and thats all? No THS7314 needed for the PAL system?

 

Well my opinion is they're all rgb and were exclusive to France. If found new in a different country, it was without Nintendo approval.

That scart block included for other parts of europe uses composite. Not really a "cable" by definition anyway. (wrong form factor)

 

yes, you use 3xR75 for the RGB lines and you got picture :victorious:
