You can replace the batteries in games that have batteries if they stop remembering the games. I replaced the battery in my Zelda game a few years back and it works great now. Take the cart apart, carefully remove the battery, and take it to Fred Meyers or somewhere to get a replacement. Just make sure it's the same volt. When you put it back in you may need to solder it just lightly or tape it to keep it in place.

The robot was called R.O.B. It came with the deluxe nintendo set. You can find ROB on ebay, but seems to go for a bit. There's only 2 or 3 games for it, and I remember that ROB broke a bit (a buddy had this system).

Does anyone know when the Top-loader NES came out in the US? I also recall seeing it about the time the SNES came out, but not sure. They are also on ebay and go for a bit.

If you have problems getting the system or games to work, here are a few hints:
- Use a air can duster to clean the dust out of the deck and games.
-The contacts on the game carts become oxidized. You should clean them. What I have done that seems to work is use a q-tip with rubbing alchohol (Not soaked, just wet). You'll see green (oxidized) and black (dirt) come off. If you can take the cart apart, you can lightly use an ink or pencil eraser also. I would recommend against using steel wool or sand paper as this may take actual metal away.
-The nes uses a 72-pin connector as the recipical for the game carts. The pins on these are pressured (to fit snug around the contacts on the game carts). After time, they loose their pressure and don't make contact. You can also take the nes deck apart, remove it, and use a needle to *gently* bend them back to get the pressure back. I did this and it worked for my deck, but be careful since you can ruin it.

I know there was a game out about micheal jackson and i'm pretty sure it was for regular nes i was wondering if you knew what that game was called?

After reading a few of these postings I had to reply...the older nintendo (original) and cartridges were not meant to be "blown" in when they didn't work. They needed to be cleaned. Like when your car battery gets corroded and needed to be cleaned to have a good connection. That's why all those CLEANERS were out there for the nintendo and cartridges. Moisture is a good conductor, but probably shortened the life of many a nintendo or sega system. Another reason for the games not working is the 72 pin connector in the nintendo. They wear out and need to be replaced.

I remember the NES Robot. It worked with the Pipe Dream game. It actually opened the pipes for you. I bought one at a garage sale a few years ago, but when I brought it home and hooked it up, it didn't work. So I just brought it back and got something else. Man, I should have kept it anyways.
I actually have a full arsenal of NES additions. Remember the carpet? I still have fun with that thing. And a few years back I bought the 4 way cordless joystick divider for 39 cents at Tops. I have about 40 games for the system. And I'm sure all of you have the gun. Duck hunt is still the best shooting game out there.
