you are a little to confisued.
1.) there are now 4 different d2pro's
i) origional d2pro (15 wire install and only d2c wii)
ii) origional d2pro + SPI addon (9 wire install which can be updgraded by dvd if you have firmware 1.1b all wii drives except d2c2)
iii) d2pro9 v1 which is the same as ii but it already comes soldered by the manfacture (same as ii)
iv) d2pro9 v2 which is the same as iii but works on all wii drives including d2c2
so if you just have the regualr d2pro you can buy the spi addon to make it d2pro9, but you may aswell have a d2pro9, Is there a black square chip near the top like this?
