Hobie-Won, Lurv, and SpoonyBard, you are wiser beyond your years. A good, thorough cleaning has made Zelda ALttP boot up on the first try for the entire morning!
These are the cleaning steps I took (all from common household tools) to clean my pin connector.
1. Use a gum cleaning dental pick. It is important to choose a model that has soft, non-abrasive bristles but is also sturdy enough to not loose any bits inside the pin connector.
This is the exact type I have

I like these because they are made of a soft rubber. Worked very well for gently cleaning along the length of the inside of the connector.
2. A clean razor brush. I have this model.

Using the softer, longer brush end, I gently swept over the pin to try to sweep out any grime and grit the gum cleaning pick was able to remove.
3. Lastly, I used the credit card in a t-shirt trick that is lightly dabbed with isopropyl rubbing alcohol (I was able to use a "green" labeled Windex glass cleaner--its ingredients are water and isopropyl).
Very important too, between each step and to dry off the connector at the end, spray the pin connector with compressed air. This is the most effective way of removing loose bits and debris.
Thank you, everyone, for you assistance. Now it is time to find me a Master Sword!
