Contact vintage video game retailers in your area that resell vintage consoles and games. Vintage video game retailers specialize in older games that are hard to find. They buy the games from people who no longer use them and then resell them to those who collect them.
Consign or sell them to a pawnshop. Vintage video game collectors often have a list of pawn shops in the area as they tend to be great locations to purchase old video games at a good price. Because of this, many pawnshop owners will quickly purchase video games from those willing to consign or sell them.
Sell your Nintendo 64 games for store credit. Places like Game Stop.com, Vintage Arcade.com and 4Jayes.com all buy old video games and offer you store credit for the purchase of new games. In many cases, you will get premium money for your trade-in because you are forced to spend that money with the retailer.
