Gentlemen, I've got some news:

The Genesis 2 AC adapter tip won't fit a Famicom, and that's good because its polarity is reversed (positive tip).
But, it will fit a FDS drive. Luckily the FDS drive contains reverse polarity protection. If you plug a Genesis 2 adapter into a FDS, it won't work, and it will cause no damage.

Will a disc system work with a Yobo Neo Fami? The RAM adapter boots up  fine, but I'm getting errors. Would a real Famicom clear it up or does it matter as long as the RAM adapter loads?

[nintendodork]

If the RAM adapter loads, but you still get errors, don't lose hope..
What errors are you getting?

[Cobra Commander]

21 and 22.

[nintendodork]

Error 21 = Disk card header block (Nintendo-HVC) wrong.
Error 22 = Disk card header block #$01 unrecognized.

So I guess it is the clone.. anyone correct me if I'm wrong

can a av mod cause rf interference? i thought my rf was shot but i tried again tonight and i had a ok picture but the more i moved my av cables around the better the picture got almost as good as when i have the av pluged in. so should i do away with my av mod its not done the right way any how i dont hear the extra sound chanles on two of my disk games and it is just a cheap set of av wires not a nice setup like nintendork has. i also like the extra sound the rf puts out so what do you think kill the great picture(av) or do with out the extra sound(rf) what are your thoughts

[nintendodork]

Well, I'd rather have the A/V quality over the extra sound IMO, it's not like HD sound or anything   The A/V is also much less hassle because you don't get ranging picture quality; you get one solid, crisp picture, and you don't have to hassle with finding the right channel..

And the only reason for your RF signal issue would be just putting cables into the Famicom.  Since the Famicom is A/V modded...in a sense...the A/V mod is always "on" whenever the Famicom is on.  So plugging cables into something that has a current flowing through it could affect picture quality, but that's the only thing I can think of..

Also, jim, if you'd like to see more pics of my A/V mod (the outside, I'm not opening that shit up ) just PM me

Ok, anytime I play my famicom on my tv, I get a good picture. But for reasons unknown, the tv just goes static for like half a second and I don't know why and then it goes back to normal.

Any ideas of what's going on and how to correct it?

[manuel]

Does it do that while playing?
When you begin playing? When you stop? Is it just with the Famicom attached? Does it happen with normal TV program or other consoles, too?

I've never encountered something like that, but such info might help people to diagnose better.

[Rob64]

It happens while I am playing and sometimes during the menu screen of a mario game or something. It doesn't happen often but when it does, it can get me killed. I am not sure if it happens on anything else, the tv is only used for the famicom. It does not recieve cable, just static.

Does that help?

[manuel]

So the TV gets static, but the game runs on, which results in a loss of a life sometimes. Is that right?

This would make me think there's something wrong with the TV, but when it's only with a Mario game, then there might be a problem with the game itself maybe?

[Rob64]

Yes, the game continues during the static. I just used a mario game as an example, this happens to all of the games that I own, so I am sure it is a tv issue.

Now that the problem is known, how do I fix it?

Without seeing the TV... get a new TV.
Or repair the existing TV. There must be something wrong with the electronics. Maybe wait until our tech-guru (133MHz) comes around, he may know something.

I have a similar problem, but mines because channel 95 is also a radio broadcast channel here. So the radio interrupts my signal, I had to use my vcr to correct the problem.
