So I got the leaked rom and tried to use it on my 4.1.0-4U 3ds with emuNANd 8.1 and got a black screen. Rom appears to be legit. Little intro at the menu loads up and you can look through the manual but it gives a black screen after the 3ds logo. Anyone get the rom to work and if so with what systemNAND? I will be updating to 4.5 tomorrow just to test it out. EDIT: It looks like your SD card has to be at least 4gb or you will get a black screen.
