From what I've scrounged up on the internet, a Genesis AC adapter will work for a NES, BUT a NES adapter should never be used for anything but a NES. Does this sound right?
Note: I tried to search for a similar thread already in existence about this subject but found nothing. If I missed one, please feel free to pop its link below.

I've never tried it myself but that should be right. An NES is AC current while the Genesis is DC, you can use a DC adapter to power an AC device but you can't use AC current to power a DC device. I believe it's ok to use a Model 1 Genesis adapter, I'm not sure about a Model 2.

This is exactly correct. The NES AC adapter outputs AC voltage, which is neither DC nor does it have polarity. The North American NES is a beast of a console that can be powered by just about anything from 7 to even 12v DC, AC, it doesn't matter. Because the NES can be powered by nearly any power supply under the sun, I don't ever use the NES power supplies I own for fear if I ever accidentally plugged them into something else.

The Genesis AC adapter contains a bridge rectifier, which generates DC power from an AC source.
With the NES, the bridge rectifier is inside the console, and not the adapter.
So, when you use the Genesis power adapter with the NES, you have an extra rectifier stage that doesn't serve any purpose, but doesn't cause any harm either, since it doesn't reduce the voltage enough to make a difference to the NES.

I've run into problems trying to power an NES with a DC supply. Volume would be very low, and muffled by a pronounced buzzing sound, and certain games wouldn't work totally correctly (as though the mapper chip was malfunctioning). I switched to the standard 9VAC supply and all was well again.

I ran my NES toaster for years with my Gen Model 1 power supply.
I tried the NES power supply on the Gen once, which was stupid, but I was young and didn't know better. It didn't fry it, but it didn't work.
My sister had an NES (also a toaster) but hers was a never version, with a textured top (mine was smooth) and IIRC the Gen power supply didn't work on that one.

My ex stepdad used to have a keyboard where using the NES adapter he had was fine with it.

I accidentally fried a nes adapter by plugging it in to a genesis.
In my defense, the room was dark and they're about the same size, my 50/50 chance just happened to not work in my favor.
The Gen was okay, the adapter,...er... not so much, =(

Usually it works the other way, the adapter would damage the Genesis instead of the adapter failing.

Yeah, I got really lucky that my Genesis didn't get fried. I did fry a portable radio by trying the NES adapter with it, though. At least in retrospect I think that's what I did, at the time I just thought the radio broke so I returned it to the store and got Kid Icarus with the refund.

Can the AV Famicom run off the Genesis AC??

It should.
I believe (though can't confirm or by any means guarantee!) from its ratings a US Gen 1 AC might also be safe for, if the plug were to fit, among stuff I may have overlooked:
Famicom
AV Famicom
Super Famicom
US SNES 1 or 2
Korea SNES
US/PAL/JPN Master System 1 or 2
US/PAL/JPN Sega CD 1 or 2
JPN/PAL Megadrive 1
JPN/PAL Game Gear
SG-1000 1 or 2

Yes,its safe to use a Genesis model 1 psu on a Av Fami.

It could be that part of the rectifier is weak. Otherwise It shouldn't happen. I had to use a spare genesis model 1 adapter for years because the original one was missing, never damaged anything.

Let me be one more person to say it's perfectly fine. I run my junker NES with a Genesis Model 1 power supply all the time. I've never had an issue with it, and it saves me from having to dig out a separate adapter each time.

Wait I forgot Virtual Boy. :roll: Since it uses the SNES power ratings, Gen 1 would be likely safe there too.

I found 2 AC adapter from Radio Shack
1. is
Input: 120V AC 60Hz 12W
Output: 9V DC 800mA
2.
Input: 120V AC 60Hz 15W
Output: 9V DC 800mA
Will both Run the NES no problem?

Provided they have the correct connector, either one will do.

You can pick these up on eBay for less than $6. I have only used it on a Super Nintendo, but the box says it is compatible with NES, SNES, and Genesis 1http://img.tapatalk.com/d/12/09/22/zumegape.jpg

Also, the Jaguar will run on a Genesis AC and vice-versa which at least theoretically means any of the others will run on a Jag power supply as well.

Seems so. I've asked around a bit, there isn't much info. But by all indications the center negative Game Gear was NOT released in USA.
