N64 RGB Cable / csync

Nintendo 64 RGB SCART Cables 
(and sync information)

Generally speaking, figuring out which N64 RGB cable to use can get complicated, so I wanted a page that simplifies things as best as possible.  This cables shown on this page will work with either the basic or advanced RGB mods.  Also, N64’s use the exact same cables as the SNES, so the links will be the same for your region.



Hopefully your N64 RGB mod specifically addresses csync.  If not, I suggest using luma as sync, or fully-shielded cables with composite video as sync:

Super Nintendo SNES RGB SCART cable (NTSC)  /  ‘Packapunch’ Shielded version  (UK Seller)

Super Nintendo SNES RGB SCART cable (NTSC)  /  Upgrade to shielded version (US Seller)


PAL N64 RGB SCART Cable (Do not use an NTSC cable on a PAL console)

If you’d like to avoid any potential issues and get a cable that’s guaranteed to work, I strongly recommend getting a fully-shielded cable that gets sync from composite video (cvbs);  This will guarantee compatibility with all RGB-modded PAL N64’s and th efull shielding will eliminate interference normally caused by cvbs.  If you’d like to save money, you can get an unshielded sync-on-luma cable, but it’s been noted that some versions of PAL N64’s have issues with S-Video, meaning the luma output might cause problems.
Either way, you can get c
ables with a sync stripper built in is available if csync compatibility is required, however most setups will already have another sync stripper in the chain.

Fully-shielded SNES RGB SCART cable (PAL)  /  Sync-on-luma unshielded version  (UK Seller)

Super Nintendo SNES RGB SCART cable (PAL)  /  Upgrade to shielded version (US Seller)

Once again, please make sure to never use use an NTSC cable in a PAL system!!!


Getting csync directly from the N64 (this gets complicated, I really suggest just using the cables above):

Basic RGB Mods:
I’ve you’ve installed a basic RGB mod and you have motherboard revisions NUS-CPU-01 or NUS-CPU-02 (and some -03’s), they might actually have csync (but not RGB) already connected to pin 3 (csync) on the multi-out (not PAL!). If you have one of those board revisions, you’ll most likely be able to just purchase a NTSC SNES RGB cable that gets sync from the csync pin. I say “most likely”, because I’ve seen csync from some N64’s work on some equipment, but not others. For example, I had an N64 that worked on my RGB monitor with a csync RGB SCART cable, but not through my switch and capture card which are pretty sensitive to sync.

For more information on which serial numbers have each motherboard revision, please visit these sites:

As an FYI, the NUS-CPU-03 (pictured above) and newer revisions I’ve tried don’t have csync run to the multi out.  You can try to get sync from pin 14 of the VDC-NUS chip and connect it to pin 3 on the multi-out, however I’ve had mixed results with this.  More info coming soon.


That’s all the info I have for now. I’ll continue to update this page as I learn more about N64 csync and please contact me if you have other info.  If you’re looking for more information, mmmonkey has a few pages dedicated to this as well, here and here.


Feel free to head back to the main N64 page, or head to the main console section to check out mods for other consoles.
