Hi, I recently bought a R4i-SDHC Card for my little brother. (http://r4i-sdhc.com Red Box). I formatted the SD Card with a SD Card formatter, got the newest firmware and put a few games onto the card. Some games work while the majority does not. When I boot the games, both screens of my NDSi XL turn white (in rare cases black) and nothings happens then. Is there a reason and a solution for this? Any help is appreciated.
