Rune Factory 2 Problems

Okay, I'm having some problems with Rune Factory 2. Some times, the game won't even load or it does load and then I try to save and it freezes on me. This has also happened to me with the other Harvest Moon games as well.

Are you using an Emulator or a Flashcart?

I'm honestly not that sure. It says M3 DS Real on the cover.

Then that's a flashcart. Have you updated your firmware and/or backuped and formatted your MicroSD?

I have no idea how that is done. Is there a specific website or something?

Firmware is found from http://www.linfoxdomain.com/ds/, check if you have the latest (firmware version should be stated somewhere on the menu. To format, just backup (copy everything on your MicroSD somewhere), right click your drive, and then go Format.
