I am cracking a new 3ds xl. Following the 3ds.guide tutorial, I am in step one. It is asking me to run ntrboot_flasher_nds.nds using my flashcart's nds playing capability. Either my R4 Dual Core cannot play .nds games (probable) or something else. Does anyone know what to do about this? When I launch the ntrboot nds file, both of my screens go white.
