I just got my flashcart in the mail and i looked up a couple of guides and videos and just cannot get this thing to work. I tried on my CFW 3ds as well as my DSi and it just keeps giving me a black screen when trying to boot up. I'm also having trouble understanding what files i need on the root of the sd card. If anyone provide me some help, i'd truly appreciate it. This is the flashcart i have. Sorry for the big picture. Will try to fix in a minute.
