I have some questions about the issues that arise from using .3dz files and save games. What exactly is it that makes save games from "headerless" roms incompatible with .3dz roms that do have a header? If I understand correctly, "headerless" simply means that the header is empty/contains only 0's. Is this correct? Does the save incompatibility issue arise due to the save file referring to the specific header, or is it encrypted by the header in some way? Does this issue only arise when the .3ds extension is changed to .3dz? AKA if I use a rom with header, but leave it as .3ds, would the save file still work on headerless roms? Would a .3dz save file from a rom with header work on a .3ds rom without header? Would the header be extractable from the save file? I am asking all this because I am worried that uploading save files from my legit rom dumps could lead to me sharing my header with basically anyone that gets ahold of the save file. Any help and clarification on these issues is greatly appreciated!
