This post is more or less just to demonstrate how I'm an idiot, and how you can avoid being one too. My EFA-Linker has always been a favorite item among all the little gizmos I've bought in the 'gray market' gaming hobby, right up there with my Adaptoid. (from my cold dead hands, heh) Anyway, the EFA cart seemed to go on the fritz about a year ago ... games would show the intro but no gameplay, sometimes the client software would freeze up while writing a game to the cart, and other failures. I put it in the desk to gather dust. But last night I was digging through the junk in the drawer and noticed that my EFA cart's USB cable had turned green inside, i.e. copper corrosion. I had to search for a while but finally found the spare cable that came with the cart, and BINGO. My EFA cart is working perfectly again. I dont know what made the inside of the original cable foul, and perhaps it'll happen to the one I'm using now ... but for now my GBA-SP2 is back in action. I was an idiot not to have considered the cable as a cause when the cart started going bad on me. No matter what kind of GBA cart you run, if there's a cable involved make sure you take it into account if you're troubleshooting. That is all.
