About replacement connector , there are clearly two quality , i have one, made in Taiwan equivalent to the original one , it work perfectly ,Turk182 in this thread should have one also.
This is what i found on another forum :
"There are two primary manufacturers of these connectors. One is located in mainland China and the other in Taiwan. The product from China is definitely the inferior product. I picked up a few of the Taiwan connectors a while back and have used them to fix 5 units so far. Each one performs like new. Yes, it's going to be a little tighter than the original connector, but nothing which is damaging to the carts and it's not a struggle to insert/eject games."
The BLW is certainly a great product but the shipping cost to Europe is overpriced...
