Hi i currently own the red box that is the R4I 3DS SDHC. It was working fine until recently when i dragged and dropped Pokemon white 2 USA rom onto the card. After that my nintendo DS lite won't even acknowledge that the R4 cartridge is even in the system. It says No card in ds slot at the regular nintendo ds lite home screen. My white nintendo DS lite is version 5, i've done the screen test and it showed me 2 pink screen or magenta color. I have tried reformatting with the SDFormatter from the site several times, i've downloaded the latest files from the website and put it on the micro sd card and into the R4 many times to no avail. I have even tried Wiping the cartridge clean with a tissue. I have no idea what the problem could be, is there some systems files that i have to play around with or something, please get back to me if you can thanks alot. Sincerely - Customer who purchased an R4I 3DS SDHC.
