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

Its not better picture quality its exactly the same.

 

I see... so all this time the THS7374 tests and the search for an external rgb-amp was pointless ... I will try tomorrow with direct wiring + resistors and I will report back
I might even solder the missing components, at some point if I am not satisfied... xD

 

Arughm now I'm confused again! What Bad_Ad's saying makes sense, but I am worried that I might get better picture quality if I do the more complex mod! He knows his stuff, so I think I'll go with what he's saying unless someone can prove otherwise.

Well, in either case, I have 2x NUS-001(FRA) coming soon fresh from France

 

No. I've made test myself with the various RGB mod available, and remplacing the components made the best image quality so far. You can see screenshots here.

 

I have 2 french n64s here right now, one done with the extra parts and one with the mod I described above. Both are the same.

Your link seems to compare a few external amp mods vs fitting the extra parts on the board (so using the internal S-RGB amp already in the console)

The mod I am talking about is the same as the extra part mod, just connecting them directly so people dont need to solder small SMD parts.

You have not compared this mod, so....

 

I just tried with the 75 ohms resistors in the 3 lines, I get a picture but it's dark. I am using a custom SCART cable that has 220mf caps in the RGB lines btw... will try tomorrow my original PAL SNES cable...

 

Is the reason the picture is dark is due to your cable's construction? The research I've done says 75 is the sweet spot.

 

Its probably the cable.

If I recall, I have no caps in mine (do remember, I did this mod like a year ago - I have a bad memory at best). Original PAL snes cable also works fine IIRC.

I could check my cable when I get home.

 

yeah it's probably the cable , IIRC the SNES does not work with it... I was tempted to remove the caps but after opening it I saw that it was well-built with insulation tubes and everything nice and tidy so I decided to just get the snes cable tomorrow and try it then LOL , no need to butcher it

 

The PAL SNES cable works? I would have thought that the extra components you put into a PAL-version cable to correct the brightness would create problems! Anyway, if you could confirm what cable I need, that would be great!

Okay, so in addition to some wires, I'll also need 3x 75 ohm resistors? Is that all I need? What resistors should I be looking at? I've done a search on eBay for 75 ohm resistors, but I'm seeing descriptions that includes watts, tolerence and carbon films, and I have no idea if any of this is important or not :\

 

Yes, thats all you need.

I have a genuine pal snes cable and the 3rd party GC one I modified for the N64. I will check them both (and detail whats inside the GC one) when I get home (assuming I remember). There is no extra parts in a pal cable over a NTSC one though....

You change a NTSC cable to PAL by removing the caps?

 

Oh, I was of the impression that PAL SNES cables need extra components in them to correct the brightness. Do you find there's any difference between the genuine PAL SNES SCART cable and the GC one you modded? Well, anyway, let me know what you discover when you get home!

Also, I refer you to my previous post, when it comes to resistors, is stuff like wattage, tolerance and the like impotent?

 

Doesnt matter, get any.

 

AFAIK PAL gamecube and snes cables are the same, IIRC you can mod a gc cable by removing the 3x220μf caps in the RGB lines and it will work with the SNES... IIRC that is...

 

Thanks, I've just placed an order for some 75 ohm resistors (100 of them! This was about the smallest bundle I could find!). They're 1/4W 0.25W 1% Metal Film Resistor 75 ohm if that means anything

 

PAL gamecube cables are the same as NTSC snes cables. (they have caps)

Remove the caps and you have a pal snes cable.

 

at this point I am going to take the topic slightly off topic...
could the reason of the THS7374 IC overheating be the fact that the signals coming out of the rgb encoder are amplified?

 

You weren't taking them from the S-RGB chip (which is the amp). You were taking them from the VDC-NUS chip which is unamplified.

 

^ I get it, gracias

 

That might explain why my PAL SNES SCART cable doesn't look right on my NTSC SNES, but the PAL GameCube cable is perfect
