The pictures aren't very detailed but I don't see something wrong. Its a good thing you get a blue screen without a cart in my opinion.

Did the game come with the console or did you buy it seperately?

Hi,

i went to the market to buy the spray, after various clean on the 2 slots (when insert the cloth with the card it was clean) and clean the cntact card not see any solution.
I put in the earphone and i heard alternate buzz when the cart is in.

I bought them separately. i will try again to clean both.

Thanks

If i try to open the cartridge we can see anything can help to risolve the problem?
Well i dont see why not. There are videos on youtube on how to open one without causing damage, its pretty easy. Take photo as soon as you open it so you know exactly how to put it back.

I have a question can be the problem in the 2 slots, i don’t know for example unsoldered part on the slots? In this case the diagnose test reveal this type pf problems?

No, the diagnostic cannot detect such things. I dont think the problem is a cracked solder point of the slots, anything is possible but you have to go with the most probable, which in this case is a bad cart.
The only way to be certain is to either find another game or another aes console to try.

Hi,

i successfull open the cartridge and i see this:

contact.jpgcontact2.jpgcontact3.jpgcontact4.jpgcontact5.jpg

as you can see everywhere the contact seems ruined (lost the golden contact) so i presume that whe i insert the cart in the console there isn't the correct contact and the correct transmission among them.
You can confirm this theory? if yes you have any idea if it is repairable?

thanks

Here is a link with scans of a legit cart of Fatal Fury 2 for you to compare (its easier for you since you have it on hand)

From what I can see I think that someone has tined the contacts using solder, a soldering iron and solder wick. This is a method when the contacts are very corroded or damaged somehow. This isn't bad. I have done it on other retro computer expansion slots myself.
So, the cart has been definitely opened in the past by someone else. Was it sold to you as "working" or "untested" ?
The contacts don't lose their gold copper color on their own.

The best way to clean dirty contacts since you have the cart open and have very good access to them, is to rub them with a pencil rubber (the white one prefferably since its softer, or the orange one)

After you clean them as much as you can, them rub the contacts with alcohol.

If that doesn't help then it's probably a bad cart.

Also check for anything suspicious on the other side of the boards. Do the boards look like they have been tampered with (besides the contacts)

JammaNationX,
You're comparing a very high quality power supply with the Chinese built one you have now that doesn't even output close to 1A when tested. You'll be lucky to even get 500mA out of it.

What Xian Xi is saying might be absolutely true.

I'm using a 10V 1.2A PSU and the AES is working perfectly but my PSU is made by SEGA.

Whatever you try be VERY careful of the polarity otherwise you'll fry the console. You need center negative.

Which psu sega is your for what console
Model No : 1602-05
10V 1.2A
Center negative


There are a few different model numbers with the exact same specs.
You absolutely need center negative and 10V 1.2A

The one in the photo you posted is for the Megadrive 2 and is NOT what you need, it also has the wrong polarity,

Updates: i bought the psu correct:
D910CD3E-8702-40B6-944F-E39080C0105B.jpeg

to find this i bought entire mega drive 1 and in the end i try again to start AES without cart always blue screen, with cart nothing always gargabe

Sum up, i try to clean with the pencil rubber all the electric contact and cleaned ti with alcohol.
I replace the psu with sega psu always screen blue without cartridge always garbage.
The cartridge was used and tested OK.
For other test i don’t have other aes and in this moment i don’t have any cartridge but i bought a new one but will arrive in 13th april.
Do you have other ideas? Or test or do you want other photos...

thanks everyone for your support
