http://www.caitsith2.net/snes/flashcart/cart-chip-pinouts.htmlWow! cool info! I suspected something like that, but you Sir, definitely know your pinout! 
Haha, thanks, but I just used Google. That's half the fun for me, learning how these simple, proprietary machines work.
I never noticed the actual CIC pinout on this page until just now. I was skeptical on it working at first, but the CIC really is incredibly simple. I'm quite certain that's how those adapters work now that I see how simple it all is. Makes me think that almost any adapter will do the trick. If not, would probably work with a very simple modification to the cart.
Once again, glad it all worked out for you. It's nice when that happens.
