Every time I change games I lose all my save data. Is there something I need to do?
Be more specific... "change games"? You mean cycling to the next game? Or "change games" as in deleting/writing them in Diskwriter?
What 3DS system are you using? What firmware? What version of Diskwriter? What template are you using?
Which game? Is there just one? Or all of them?
Need more info to work with here...
If you are saying deleting games from mSD and putting back, then you need, in diskwriter, click with right button on the game, and backup save data. And when you put the game back in mSD, right click on the game and restore save data.
The same happens to me when I play EEPROM YES games on my red button version. I had Codename STEAM and Majora's Mask.
Played Majora and saved, played STEAM and saved, Majora's save gone and created a new save, STEAM save gone and created a new one, repeat.
Then tried using Sky3DS tool to convert them to EEPROM NO: The save remains fine, but it freezes randomly. The mSD is a Sandisk Extreme Pro 90/95mbs if I remember right.
EEPROM-YES games are standard non-NAND games. These should be working no matter what. The NAND games (EEPROM-NO) have savedata written to the SD on the 3DS. Some EEPROM-NO games also save data to 3DS SD. Anytime your game prompts "saving to SD card, please wait" or at beginning "creating save on SD card" the backup of the game itself won't help.
You have to make sure of two thing:
1) When you write the new copy in Diskwriter that you aren't changing the template header IDs. The moment you do this, the game thinks it's a new cartridge and must make new savedata on sysNAND SD.
EXAMPLE: I have Ult NES Remix. I delete it in Diskwriter. I don't do anything to my template but update it to latest version. I re-write to mSD. Still thinks it's athe same game and my savedata works. The moment I insert private headers, savedata is lost because it thinks it's a new cartridge.
2) Make sure your backups aren't old. IE, BACKUP SAVEDATA RIGHT BEFORE YOU CHANGE ANYTHING. Doesn't hurt to BACKUP GAMES. This basically creates a double backup of the savedata. Just in case. If restoring the game doesn't work, write the original .3ds to mSD and then restore savedata backup.
Remember, the Sky3DS is acting like an original cartridge. So any savedata that games creates on the system's SD card will be made. If you use a copy and any of the .3DS file is different from the one before (including template), it won't access the savedata but instead create new.
Best to save in 1.06 THEN transfer to 2.02b1. Please skip 2.00b8. It had formatting errors. So you can try, but no guarantees it'll work.
As for anyone saying 2.00b8 "works fine for me" wait till they update to 2.02b1... gonna open up a can of worms and find out how bad 2.0 was.
Easiest thing to do, have at least 2 games on Sky3DS. Save your MM game. Click the button to cycle to the next game (it writes from eeprom to the microsd card) The trick is to cycle game after you save (and exit the game, of course)
