[devilsminion]

I was so sure after reading about the hot swap I would not have to many difficulties with this chip but now I am not so sure. There is two parts the chip and another with the switches. I am trying to find out where I can find a visual diagram on how this is hooked up. First is it necessary to have it, I assume it is but want to ask anyway there will be no using live and I just want to back up my own games. Other than that I can do the rest, but I can't find a link with some pics of the "New" X2 lite I would appreciate your help!
