Available solutionsRemove old save file, make a copy on your pc.
Download encryptDS.exe and try to 'encrypt'
and then 'decrypt' the rom. (find the program via
Google)Backup all data on your SD, format it and add a secondary firmware such as
YSMENU, or try using pre-patched rom, use DS-
Scene Rom Tool if needed.
