So I have this old N64. It's been with me for a couple of years, previously owned by a friend, but treated pretty well. The only rough treatment it ever had was having the cartridges slammed down when they didn't connect right. When I got it, and the games with it, I spent loads of time playing through everything (it is my only console). When I was done/too busy to focus on games it got packed away and forgotten for a few months. Then I found it again and decided to replay OoT. I started a new game, ran around the village for a bit, and headed out onto the plains to go to Lon Lon Ranch.
About thirty seconds after I got onto the grassy area, around the time it started getting dark in the game, the whole thing would just freeze. No button would make it do anything, and it would sit there indefinitely without waking up. I had to unplug it and restart. It kept doing this. I blew out the cartridge, even used a tissue to dust it and the console off, and that did nothing. The strange thing is that I can spend as much time as I want in the forest or the Kokiri village, and it won't freeze there, but without fail, thirty seconds after going to the plains it seizes up. The other games seemed to work fine last I checked.
Does anyone know what's up with this, or how to fix it?
