I was researching but could not find the info I am looking for so if anyone can tell me if GC2-D2C (v1) is compatible with playing Wii backups it would be much appreciated.
Yes, it can.
I assume you already knew this, but I will say it for those who come looking for the same info as you. You will need your wii modded in some way of course.
