rune factory 3 help

when I play rune factory 3, my save file randomly corrupts,does any one have the same problem, and how do you prevent it from happening.5th try to play through it now :(

Wrong section -> technical help.
It's anti piracy. It prevents you from playing this game without paying for it.

Back up your save, and create increments, so like:
Rune Factory Save001, Rune Factory Save 002, 003, 004...Or get a better flashcart. I'm assuming it isn't an R4, CycloDS or EDGE.

Or depending on your flashcart you may just need a firmware update to bypass the anti piracy.

i can give u my save file if u want it on winter and u can marry some girl
