They made a pretty good quality Gamecube S-Video cable which will work with the N64 aswell:-Īnd its usually available on eBay for less than $10 I dont usually recommend 'Monster cables' but in this case they may be you best option outside of the official Nintendo S-Video cable. Sounds like a similar issue, and somebody at the bottom of the thread said they solved it with a higher quality cable so it could indeed be the cable aswell. I also came across this thread from another forum:. The official Nintendo S-Video cable is well shielded but is really hard to find as it was only sold at retail in Japan, and in the USA it was only sold online Almost all third party Nintendo S-Video cables I have bought have been quite poorly shielded (and poorly made to be honest) Although it really depends on how much EMI/RFI interference is nearby to cause any noticeable image degradation. It could be that because the Luma/Chroma signals on a PAL N64 are not at the 'correct levels' your video processor is having trouble processing the signals, so perhaps the dots/netting is being added during the processing stage due to the incorrect signal levels.Īlternatively, aswell as the missing components, it could be that your S-Video cable just isnt well shielded enough.

When I used an S-Video cable with the components still missing with my PAL N64 on my CRT TV I just got a washed-out overbright picture, no dots or netting as far as I can remember. To be honest I have no idea what causes the dots/netting/masking. Its also interesting to note that almost all third-party Composite AV cables are designed for the NTSC market aswell, so also miss out the 75ohm resistor and 220uf capacitor - many people dont realise this and wonder why their composite picture doesnt look very good (Not that composite looks great anyway!) Also many import gamers often get their nintendo cables muddled up aswell and dont realise it makes a difference. I think its a shame that Nintendo decided to 'region lock' video cables - it just takes region locking to the extreme (and I cant see any other reason why they would do it other than region locking) It meant that many PAL N64 users didnt even get a decent(ish) S-Video picture from their N64 and had to put up with the Composite/RF output. This thread is what got me interested in the problem, although they didnt seem to use the same solution:. If you try using an 'NTSC' S-Video lead the output is overbright and washed out, I looked everywhere for a 'PAL' S-Video and couldnt find one anywhere (and I looked on every European eBay site) so I very much doubt they existed. I think it would be useful information for the Wiki though if someone wanted to add it (I may try and add it myself if no-ones interested, but I havent really used a Wiki before and am worried I might screw something up!) I had intended to do this myself and put the circuit inside an actual S-Video Cable, but havent got round to it yet as I have been more interested in the N64 RGB mods. Im glad my info was of help to someone Even though its only for S-Video The pics don't show the true extent of the difference, but you get the idea.

However, thanks to Nintendo's awesome (read: not that awesome) anti-aliasing, this is probably the most not-so-worth-it video mod I've ever done. The key difference here is a complete lack of dot-crawl. I just used 2 33s in parallel) and put it together. So I get the parts from my local Dick Smith (they didn't have any 68nF caps, typical of them. The luma needs a 74ohm resistor to ground, and a 220uF capacitor in series, while the chroma needs 75 to ground and 68nF in series. For whatever reason, Nintendo left out components from PAL 64s needed to get a good s-video signal, so the Y and C from the AV-out isn't suitable.
Working with Link83's observations in this thread, I went ahead and added a hard-wired s-video cable to my 64.
