You're going to have to reinstall the games from the CIA files. As for the save files, you can either do a system transfer from the old 3DS to the new one, or you can use Checkpoint to backup the decrypted versions of the save files and restore them.Ok
Bought my son a regular 3DS last week and used soundhax.
Installed a few games on it and he's played them and has save files.
Today bought a 3DSXL and again used soundhax
I don't mind installing all the CIAs again on the XLs SD card but how do I transfer his save files from his 3DS to the new XL ?
