Hey Guys, i'm new here and english its not my fluente language, so, sorry, i gonna try. I bought a R4sdhc dual core has one month, and it still working until now. So i found a 8GB sdhc card on my desk and i want to use that. I formated like the same way i did before, and put that on my r4 and tested on 3ds. When i open that shit on 3ds its opened with a small screen, not the default like is before (the normal screen when you start a DS game on 3ds), sometimes, run okay, but, only for minutes. And when i go to the game folder, on r4, appears the following mensage: "errcode=81, errcode=83 SD Card Fragment error! Backup SD card, then perform full format with panasonic SD formatter." I did that, like a... thousand times, i think? I tried the old sd card, the same error I need help, really. I dont know what happened to my r4 (move it if is on wrong place) Edit 1: I think the problem is on the r4, when i start he without the sd card, he start with the same small screen (like that http://www.nineinchsandwich.com/wp-content/uploads/2011/03/3DS-small-screen.png), anyone can help?
