But doe
But doesn't card2 mean no trimmed games, and more importantly what can cause a 3DS to freeze in the first place. Also what is this savedatafiler, and with real time saving are you saying saves are stored to the sd card while playing the game instead of on exit of the game to the 3ds home screen?
I am not sure about the trimming stuff. Maybe you gotta ask others or Google yourself.
No idea what cause the freeze, but if you encounter one, your save data would be corrupted and cannot be used.
Unless you have backed up your saves, you would need to start over or download someone's else save.
With card1 games, you need to return to home menu in order to finish the saving proceed for GW.
The save is temperately stores in the SD of the red card when you are playing, and would import to the big SD of 3ds when you return to home menu. For card2 games, when you save, the save data would be instantly stored in the Rom, which means a real time saving.
Savedatafiler is a tool to manage your save files for card2 games and Cia games.
You can convert card2 save types to via type, and vice versa.
