The D2C dvd drive control chip ....
just has 1 row of numbers/letters "
GC2-D2C "
There is no 2nd row of characters below the GC2-D2C like on the moddable Wii's
AND
ON the left of the chip just below the hole in the center ...it is printed with
APCB D3 94V-0
This Version is called the D2C2
so far it has been proven correct and the only sure way to id the Unmoddable Wiis
hope this answers the often asked question....
