Recently I contacted fellow Roundtable participant dsullo about a new 72-pin connector for my NES. He was a great guy to deal with, very flexible and accomodating, and I purchased from him both the connector and a bit to open NES cartridges.
Well, I've just finished installing the new connector, and using the bit. It was hard to resist popping a game in the slot as soon as I got the NES back together in order to see the results, but he strongly recommends only inserting cleaned cartridges in the system so I restrained myself and decided I'd clean a cart first.
I couldn't find the recommended white eraser, so I used a red eraser on the end of a pencil. As I hadn't ever opened an NES cart before, nor had I ever used the specialized bit before, I chose Mario Bros./Duck Hunt as my guinea pig, as it were. It's a little unfortunate, because I never really cared for that cart and it's not the most exciting game to pop in. But for testing purposes it'll do.
OK, so everything is cleaned, reassembled, etc... I hook up the NES, plug the cartridge in, and power up....

. Ohmygoditworks! Yes, for the first time in my life I have seen an NES power up, loading the game perfectly, ON THE VERY FIRST TRY! There was no wiggling, reinserting, or blowing on the contacts! It just worked. It was amazing.
SO, I decided I'd try out Duck Hunt, as I'd never played it and it always looked a little bit fun. Also, whenever I watched it people would cheat by either holding the gun right up against the screen or just aiming at a lamp or something. I wanted to really try and aim and play 'right'.
So I'm sitting and trying, and missing consistently. Then I repositioned myself so I was sitting in front of the TV instead of off to the side, and all of a sudden I was scoring hits.
Does the Light Gun (or all light guns) only work properly when you are pretty much directly in front of the TV, as opposed to sitting at a 20 degree or so angle?
Once again, I have to vouch for dsullo and his NES replacement parts. If you're looking for that sort of stuff, check him out!
