About the new features:
1. A variety of encryption methods are used in the existing savegame. When the encryption
method is Ver6.0, “Backup 3DS Savegame” file is *.zav. This save file can be used in flashcard,
and it is online supported, it can also be restored to the original game card(card A to card A)
2. If the encryption method is not Ver6.0, the backup file is *.sav. This save file can be used in
flashcard, it can also be restored to the 3DS game cartridges (same games), of any ID.(Card A to
Card A/Card A to Card B). Or via the Sav to Zav function, to generate a new *.zav file. It is online
supported after conversion.
3. As the previous ROM files do not contain the save file information, all the generated save file
size is 512K. If the actual game save file is 128k, we can’t “Restore 3DS Savegame” 512K save
file to 3DS game cartridge. To solve this problem, our dump ROM files contain the save file
information, and all the save files can be restored to 3DS game cartridge.
4. When Sav to Zav function works, the ROM file being read must contain ID information.
