I'm planning on getting my first 3DS flashcart and there seems to be several version of the R4 (r4 revolution 3ds, r4 wood, etc) and was wondering which one is the best (assuming they're all around the same price range)? I already have an 8Gb micro SD so I just need a standalone card. Also, are the flashcards region locked? I live in Canada but am travelling to Europe and noticed that there are some retailers there who sell these in France and Germany. And one more thing, will these cards be updated to run 3DS ROMs when an emulator is discovered or will I need to buy another card? Thanks. EDIT: Most of the retailers are sites, are there any stores I can go into in France, Germany, Switzerland or Austria that sell these?
