I've got the d2pro (v1) 19-wire (region free) profesionally installed in my Wii. Wii is NTSC 3.3U, and the d2pro is still 1.0 firmware. I've seen that d2pro website shows the firmware now available up to 1.3. I'm planning on holding out until I see few titles that start to not work because of the d2pro (or a console update i've done) to get the d2prog device (to do firmware updates to the d2pro). But does anyone have any change logs (i can't find any on the website) or details on what these updates do? As to now, even with update to 3.3U, I still haven't had any compatability issues (even with newer releases).
