The DC encoder is a Sega Brand encoder. It's hacked into very professionally. It's uncool to get into a price war on my own thread but my work stands for itself. I work for Capcom and I know what I'm doing. Check out both of our sites and compare the work.
Yes it has the D-pad, 6 buttons (including the triggers, set to digital) and the start button for 7 butttons total. The VMU slots are also there so that you can keep a VMU inside of your sticks case.
Tested and guaranteed. I'll also email you the wire code so that you know which color goes where of course. No two wires are the same color as I use stock 15 wire cable.
Edit:
He may edited/deleted his post but I still think that under selling someone in their own thread is in bad taste.
