Hi! I bought a R4i Gold 3DS (r4ids.cn). This one exactly: http://www.digibay.es/nintendo-3ds-flashcard-/79-r4i-gold-3ds-flashcard-para-nintendo-3ds.html It arrived today and I'm trying it on my 3DS (11.0.0-33) I downloaded "WOOD R4 V1.64" from r4ids.cn and placed it on my microSD, and some DS games. Problem: It's like it gets corrupted each time I run it, and I have to format my microSD. And when a game wants to write data or save on the "cartridge" it shows an error, "Unable to write data". But I can start a game in "Pokemon Mystery Dungeon" because it doesn't write data at the beginning. Also most games stuck on "Loading" screen. This is how my microSD looks: root: http://i.imgur.com/bTmRh7O.jpg _rpg folder: http://i.imgur.com/XoqWiko.jpg Now, this is how the "program" looks the first time I go into it in my 3ds: http://i.imgur.com/tvJb85C.jpg It looks fine. But if I run any game, it can't write data, or won't load at all. Now I turn it off, and go into it again: http://i.imgur.com/bYsUxKm.jpg It's already corrupted, Interface doesn't show properly. Some games load but won't start because they can't write data: http://i.imgur.com/j7UFe1f.jpg http://i.imgur.com/RotI51i.jpg And this is how the _rpg folder looks: http://i.imgur.com/UtTQOpq.jpg See the "ui" folder? now its called "ui `" and I can't open it: http://i.imgur.com/s2gbt3E.jpg "Access denied" Sometimes every folder and file gets corrupted, file names and extensions changes to weird ones, and sometimes I can't even go into my SD and I have to format it directly. I tried 2 different microSD, so that's not the problem. And they work well for other purposes (one of them I used it to boot Windows, and the other one it's on my phone) Am I doing something wrong, or is my flashcard broken?? Hope anyone can help :\ Thanks!
