I've just (finally) finished adding the pictures to my M3DS real review. Sorry for being late with the review (relativly speaking, as I was the first with PCB shots writing the review took me a long time). But to make up for it I have 2 great news items regarding the M3DS real. The first is regarding DS homebrew and the second is regarding original GBA saves (<-- direct links). Neither of the two features have (accuratly) been mentioned by reviews (or even the M3 team) before (afaik)!
To find out what those two items are specifically read the review (don't worry, you can quick jump from the introduction to the 2 big items) !
