New Superjoy problems

goodie · Post by **goodie** » Fri Dec 03, 2004 5:13 pm

My first superjoy died, so I've obtained another one. For the most part this one seems better. The games are not built in, so it should be easier to get Nes cartridges to work. Its sound sounds a lot more like a real Nes, and the PCM samples don't sound trashy. So I should have a portable Nes made pretty soon. However, there are a couple of problems I need some help with.

1.There is constantly a loud buzzing noise. How do I get rid of it?

2.The color looks kind of weird and washed out. (If you've ever tried to make your own composite to s-video adapter, the color looks a lot like that.) How can I fix the color?

3.There are several vertical lines in the picture. How can they be removed?

They will work. Ben just couldn't get the controllers to work with it. Besides, according to his photo of it, it was a really old "y2k" version. Mine is a much newer version, so it will probably work.

In this post it is mentioned that low pass rc filters can help. Anybody have information on them?

YES! I've finally got my Superjoy to work with NES cartridges. Now if somebody could just tell me how to clean up the audio and video...

It been mentioned before that you should shield them. That way they pick up less interferiance.

So, how do you do that? Would I need to shield the Superjoy itself or what? There aren't really that many wires on it.

There is stuff to put over the wires, much like chargers or things like that (also thing cat5 lines). You may find it at RadioShack, I'm not sure though. The kind my dad had went over the wires than use a heat gun to shrink it around the wires.

oh yeah, and don't forget, for the shielding to work you must tie it to ground.

Sorry if this sounds dumb, but do I shield the cable that I'm using to connect the a/v to the tv? Or is there a way you could shield the a/v traces on the board of the superjoy?

you should shield the cable, although under 1 foot of cable shouldn't need to be shielded.

On Mark Knibbs' site, he mentions the stripey graphics thing with the Super 8/Tristar. I own one of those and another NOAC, and both have the stripes to an extent. Mark's fix for it involves using a capacitor, which seems to have worked (I installed one in my Super

Sadly, he doesn't include info on where to put it for the NOACs in general, and I don't have my Super 8 handy.
