Need some help... bad...

I want to make a NES portable but have some major questions:

1. does the input voltage have to be exactly 5 volts or can it vary up to 7.4 volts like most other systems? I'm connecting the voltage to the 5 pins where the RF modulator used to be if that makes any difference...

2. I have absolutlly no idea how to get my video and audio
out of the mobo, searching online, I found that you have to recreate the amplification device to get the signal high enough. Is this true? can't you just hook your AV wires to the mobo in a certain place like all other systems?

3. also, for some reason, when i hook up the power to the mobo, the NES starts up right away, no matter if i have the power on or off, it just does its on and off cycle of the cartrage is not in or stays on when its in correctually although I have no way of checking if it really is broken because i cant use any AV

. could this be a side affect of not inputting the right voltage?

and I thought this system would be easier then the N64..

Why don't you just use a NOAC like the Super Joy 3/Power Player?

They almost have 100% compatibility, but a Yobo NOAC is better.

maybe because he wants to use the NES he already has... Anyway, as for the origional question, you can ONLY put 5 volts into the NES motherboard. DO NOT use anything more! You will fry it, I know from experience. Use a 7805 to cut a hugher voltage down to 5 volts. As for the amplification, I did need it, but only if I hooked it up to a TV. It seemed to work well on just the PSOne screen I had. Try it out and see. I could also maybe post a picture of the pinout here, but I don't have the link handy. Look for the nestable on google, that guy has a pinout for sure. He also has instructions for the amp. Email him if you like, I did and he seems like a nice guy. Good luck dude!

the power problem is pretty easy to fix. Do a search for NES power switch & you should be on your way. 4 rechargable AAs will give you 4.8 volts, so that's usually easiest to work with. Also, if you're searching for case ideas, the board fits great in a DVD case. AOL even gives clear ones away!
