I have been looking around for some powered Game Boy link cables. According to this tutorial Nonfinite Electronics used to carry powered link cables.
I searched on eBay, and have found some sellers with "6 pin Game Boy link cables" and decided to order one for fun to see if it even includes all the wires. It's coming from China and will take a few weeks to get here.
Anyone know of any place I can buy actual powered cables? Or if it's possible to buy just the connector? I can't seem to find just that anywhere. I'm looking to buy at least a few of them in the future.
