I decided the other day to pull out my old consoles and see what works and what doesn't. Found out my Mario Kart 64 is broken which fucking sucks cause that is expensive to replace but anyways.
My NES. I bought it off a friend of a friend (like $20) 4 years ago or so. Never really played it except when my brother and his family was living with us for a few weeks while they were in the process of moving. During that time I could not get it to ever work, but him (growing up with one) got every game I own to work and relatively easy at that.
Anyways my experience with it so far is I got 2 games to work (YEAH!!!) but now it is back down to 1. SMB was the first game I tried and after a few minutes of the basics (blowing in the cart, up down up down, all that jazz) I got it to work and then I put in Tetris and got it work too. Super happy at that point. But since then it has been downhill. Tried Zelda (which has always been a problem), blinking grey. SMB 2 and 3, blinking grey. TMNT Arcade, blinking grey, so on. Went back to Tetris and it was doing the same. Eventually I got SMB to work again but now I can't get anything to work besides that.
Every game (except SMB) is either blinking grey or solid grey screen. I'm not sure if there is much of a difference between these screens but at least it is consistent. Are there any known fixes for this? Is it just as simple as cleaning the pins in the system? Is that fact that one game works consistently mean that the other carts are all fucked (which would be the worst most depressing thing)?
I've also been debating on just swapping out the 72 Pin with a new one. Sounds like that solves just about every problem no matter what. As someone who has never done anything with electronics, is this that hard to do? Anyone with first hand experience in doing this with any tips as I might end up just going down this road at some point.
