Did you get a replacement SD card, reformatted in FAT32 + 32 KB cluster size, checked it with H2testw, copied everything from the previous bad card to this new one, and backed up all your saves + extdata with a save manager? Like what was previously advised from your earlier thread:
1. If this is the
Super Street Fighter IV - 3D Edition (USA), make a copy of the save file and set it aside on a computer:
- sdmc:/Nintendo 3DS/<ID0>/<ID1>/title/00040000/00032d00/data/00000001.sav
2. Backup the save + extdata of that game with Checkpoint or JKSM.
3. Reinstall the exact region *.cia file of this game, launch it once, and add back the *.sav file to its directory.
4. Go straight to your save manager. Make another backup of the save + extdata and restore them.
5. See if the game launches with your old profile. If it does not, resort to restoring with the backup from step 2 (or earlier if you have another from before).
