So I thought that it was just a few games on my Sky3DS that didn't have working online, but as it turns out, the only game I'm able to play online with my private header is Smash. I just invested hours of gameplay into Theatrhythm Curtain Call and I'd really not like to lose my save file here. I'm wondering if I go into the template and figure out what the hell is wrong with the headers, will I lose my save data even if I back it up and restore it since saves are tied to headers?(Or so I've heard.) If anyone wants to help me out here, here's the simple steps I've done as far as getting my header into my games. 1. Used friend's 3DS to dump Animal Crossing. 2. Used Gateway ROM Patcher to dump header to bin. 3. Instead of patching every individual rom, I just used No Ban No Sky to highlight the .bin header and the 0326 Template for Sky to patch the entire template. I'm assuming something is maybe gone wrong from step 3?
