nonworking cart

[David J.]

Yes, I've tried rubbing alchol, and it's not really working. I bought Adventures of Batman and Robin, and my cart is kind of fucked.

There's some green stuff on the pins and a little bit of red stuff, looks like marker? Maybe I need to keep cleaning at it?

[David J.]

I give up, in the trash it goes. Thankfully it was only three dollars that wasn't mine. ;)

I'm amazed at the disrespect some people treat their games with. If that was indeed marker on the connector pins, arrrgg.. mass beheadings are in order!

[winona]

Buy a gamebit of Ebay and get some real electronic cleaning fluid. Works wonders. Ive cleaned/repaired carts that looks like they came from the planet rust storm. Cartridges are remarkably though little buggers.

I agree one of the carts I have looks like it was either in a fire or had acid spilled all over it.

[David J.]

Well, it was thrown in the trash, and I no longer have that cart.

I did luck out and got a new copy at the pawnshop.

[Obviously]

The green stuff is just copper oxidation which is the same reason the statue of liberty is green, thats why it's best to have the contacts protected by something because loose carts are far more susceptable to it. It's rust, for all intents and purposes.

My Alien 3 game for Genesis won't work that I bought a few days ago. The connector looks fine with no problems. It does not get past the Produced or licensed... screen. What could be the problem?

[landstalkerx]

If your having that problem with more than one game it may be the connectors inside your genesis are either dirty, or they have become farther apart than they are supposed to be (this happens over time.) If you believe that the later may be the problem, let me know and I can tell you how to fix it

[Melf]

My Beyond Oasis cart has this problem. I boot it up and get a black screen. I've tried everything yet nothing works. :(

That's where I found out how to do it, I couldn't remember the url though.

landstalkerx: have you done this to your genesis? i started, but it seemed like i was going to break the connectors. What's also weird is that I have the genesis 2, but my connectors look like the ones for the genesis 1, how they're open on top. does that mean i have an earlier made genesis 2 model?

[landstalkerx]

Yes, I have done it to one of my genesis'. The one that I did it to was a model 2, but it's connectors look like those in your picture of model 1 connectors. I have another model with connectors that look like they are supposed to look, but I haven't tried it on that one.

As for breaking the connectors; to my knowledge they are more likely to bend as they are supposed to, rather than break. I remember when I started doing it, I was having some trouble too, but then it got easier. I did it several months ago though, so I do't remember what the issue was. The only other issue I had was that the connectors had a tendency to turn a little bit, rather than come out straight.

landstalkerx: do you know anything about the differences between model 1 and 2 genesis consoles? read the below thread, and reply if you know if the sound on Revenge of Shinobi sounds different on my Genesis 2 simply because there was a change in audio hardware.

I know that some of the chips that they use are different, but beyond that I don't know very much about the topic. If you want to get an idea of when your genesis was made there should be a version number as well as a hardware revision number printed on the board, along with a year. I believe there are three different video chips they can have, but I don't really know anything about them. I have a copy of the game as well as about 5 genesis', so if you want I can test it out on all of them and see if it makes any difference, with the copy I have.

Yes could you test Revenge of Shinobi out on your different genesis systems, namely between the genesis 1 and 2? I know I'm not just hearing things, the instruments in the songs are definitely different! just go to the sound test and play the song that is on there (the song from the first level). You should hear a noticeable difference. It doesn't sound as good to me on the genesis 2, with the different instruments the song doesnt seem as full, and loses some of it's overall impact. If you test the game on your different genesis', let me know what you find out! thanks! :D

My board is "PC BD MD2 VA1 USA". See below, there were three different versions made, mine is the middle one made on September 13, 1993. The first and third ones have the same CPU (M68HC000 und 84C00 ). The second one has different ones (MC68HC000FN8 und 84C00AU-6 ). The first two have "PC BD MD2 VA1 PAL", and i dont see these serial#'s on mine. Are the USA versions different?

Take a look at this link:

under the MEGA DRIVE 2 IC'S, I have the first one of the three. Does this mean i have the earliest Genesis 2 model, and what others have said are the best one?

[David J.]

I'd just go on ebay and buy a Model 1 Genesis.

[landstalkerx]

I haven't noticed any difference in sound between the model 1's and the model 2's I think that thier may have been a slight difference between a couple of the model two's, but if there was it was very minimal.

You have one of the earlier versions of the model 2, but it may not be the earliest. I am uncertian, but I believe I have four different versions of the model 2. If this is the case then the list would be incomplete.
The board layouts for all of the model 2 genesis', except the very last ones are all pretty much the same, the only difference being the chips.

While this method can cause your connectors to oxide a tad faster than they would normally, lightly rubbing them with fine sand paper gets the pins nice and rough... - that makes a good connection.

It shouldn't cause them to oxide much faster than normal as by now that protective laquer should be WELL worn off.
