Well crap.

Thanks for the help. You're probably right about the 1A restriction being the reason it is resetting. I thought it might work because in the datsheet it said it would go to 1.5A before the overcurrent protection kicks in.
I woul definetlt like to get a DC-DC converter, but so far they all cost too much ($30 was the cheapest I found). I'm looking forward to seeing if yours works so I can get one.

I tryed hooking up the old setup I knew worked. I had tested it before I even started building this thing. I figured if the N64 reset with this setup, then something was messed up in the wiring. The setup was the same as before, I jsut used a 3V car adapter in place of the regulators. It worked just fine when I powered the N64 and screen off the same rechargeables (6AA's=7.2V)that I used with the regulators earlier. Since it worked earlier I know it's not the batteries.

So I hooked it up, turned on the screen and N64, and the N64 ran fine and never reset. But there was still the really awful screen lines (they were all over the place! awful! irt looked like a bad TV reception.) and weird sound problem. I'm gonna chalk that up to bad wiring.

I'll probably desolder and replace the ground wire to the screen, and if that dosn't work then the AV wires. But before I do that I want to hook the AV up to a normal TV and see if i get the same weird video and sound. If I don't then it's a screen problem.

What a pain. Thanks for all your helpful suggestions guys. I think I'm close to getting the problem found and killed.

I have the same problem as you. On games that draw lots of currrent (Like Goldeneye), the regulator starts dropping out and some faint diagonal lines starting appearing. It still appears on televisions (just noise in the pwoer supply).

You should check out the LM2670-5.0 by National. I think it supports up to 3 amps which is enough.

whew....I'm glad I'm not the only one seeing those lines ...seriously, though, those lines are pretty annoying. they're tolerable, but still quite annoying
