Ok, so I've been reading around and I'm just really confused now. This is my info: DSI XL 1.4U EZ-Flash VI VER:H F k3.0 OB1 I can play any normal nds backup. (Including Pokemon HGSS) None of those freeze at all. I just got my DSI XL and got a few DSI backups like "System Flaw" and "Prince of Persia - The Forgotten Sands" but when I try to load them they freeze. System Flaw freezes while loading. Prince of Persia loads then stays at a black screen. Please if any one knows anything that could help let me know.
