NES 2 AV Mods

September 4, 2009

I was going to do a long rant about the Wii. But since I know some of you want something with more substance, I’ll give you this instead.


Nes2The NES 2 toploader was Nintendo’s attempt to sell more NESes. The toploader design is more reliable, but it suffers from bad video output. It’s only RF and suffers vertical lines. So a lot of people AV mod their NES 2s.

The usual method (let’s call it the gameSX method) involves removing a resistor, cutting a trace underneath it, and wiring up a simple video amp. But some say it doesn’t reduce vertical lines at all, doesn’t improve quality much, or is simply just confusing.

So I went on this internet and searched for answers. Then I found this thread on the internet (after a helpful mention… somewhere).  The first theory as to why the video output still sucked was a bad PPU. Some guy disproved that by actually connecting his toploader PPU video output to the video circuit in a frontloader. Problem solved, not the PPU.

Some guy posted an alternate mod in that thread, based on the AV Famicom circuit. It involves lifting pin 21 and connecting it directly to the new circuit. This mod gives much better video output, but has somewhat reduced brightness. Apparently in a normal frontloader the video is amped again in the RF box, so that could be tried.

But was that just the answer? No. By that time I had looked through schematics, scoured the web, and found absolutely nothing in various forum topics. I’d even come up with the crazy idea of reproducing the entire video circuit of a frontloader.

Now I wish I just had a NES 2 to play around and test my theories on. Were you expecting that I had one and modded it? Nah, you can’t get anything cheap where I live, regardless of rarity.

I did, however, write this article on the ModRetro wiki.
