Hey Guys. Here is a little Guide for transfering Savegames between Roms with different Headers. The savegame is bound to the rom it was created with via th header. So if you want to use a savegame of friend or want to change headers e.g. from a public header to a private one the savegame also has to be reassigned to the new header. (.3ds → .3dz, .3dz with a public Header → .3dz with a private Header) You need: - Gateway Rom Patcher - Gateway (tested with 3.1.1 on a New3DS) - SaveDataFiler - Your Game Rom - Your Source Header (optional) - Your Target Header - A working Savegame - A PC/MAC Remember to always make Backups of your Savegames! Savegame example: Super Mario 3D Land (0004000000053F00) > http://3ds.essh.co/ 1. Connect the 3DS SD Card to your PC 2. Backup your Savegame first. It is usually named GameID.sav 3. Change the name of GameID.sav on your internal SD Card to 000400000FF40A00.sav 4. Enter Emunand 5. Mount the Rom with the Source Header 6. Start SaveDataFiler and highlight CTR Card (CTR Card won't be shown as broken if the .sav and Rom have an identical Header) 7. Press Y and then A to export the Savegame SaveDataFiler stores your saves in SDCARD:\filer\UserSaveData\20150131010203\0000053f YEAR-MONTH-DAY-HOUR-MINUTE-SECONDS \ TitleID low 8. Connect the Gateway SD Card to your PC and change the Header of your Rom to your desired Header for example with Gateway Rom Patcher. 9. Put the Gateway SD Card back into Your Gateway 10. Put the Internal SD CARD in your PC 11. Delete 000400000FF40A00.sav and <GameID>.sav if it you have it 12. Start your 3DS and enter Emunand 15. Mount your Rom and start SaveDataFiler The CTR Card will be shown as broken, but don't worry it doesn't matter. 16. Switch over to SD and highlight TitleID low 17. Press L + A and then A to create a savegame of your monted rom named 000400000FF40A00.sav 18. Put the internal SD Card in your PC again and rename the newly created 000400000FF40A00.sav to <GameID>.sav and put the internal SD Card back into your 3DS 19. Start the Game 20.
