Well, I purchased a new card about a week before 1.4.5, as far as I can tell it is Revision "C" just not patched for 1.4.5. (Has a C on the back.) Anyway, card won't update with the new patch. Just gives me a card "Failed" status. Kind of makes me hesitant to recommend buying a new card, when as far as I can tell I have a Rev "C" and it won't take the patch. You may just end up getting one like mine that won't work with what they have right now. /continues waiting patiently
I just bought a r4igold it arrived today. It works perfectly in my 3dsxl which has the newest software but when put it in my dsixl with 1.45 I get the error has occurred turn it off or refer to manual for troubleshooting
