====== SL2 ======
Dark Souls: Remastered uses AES-encrypted save files. Basic unpacker is at [[https://github.com/pawREP/Dark-Souls-Remastered-SL2-Unpacker | Dark-Souls-Remastered-SL2-Unpacker]]

Structure is
<code>
struct SaveEntry {
    uint8_t Encyption_IV[16];
    //everything after this is encrypted with the const file key and the randomly generated iv
    uint8_t CHECKSUM_HEADER[16];
