can't save rune factory 2 a fantasy harvest moon

like what it says in the topic, i can't save in rune factory 2 a fantasy harvest moon for the nds. i go to the menu and press save, but when i load up the game, there is no save file. im using an r4 Ultra with the latest firmware, which is 1.55.

Look on the r4 to avoid list. R4 ultra is on the avoid list. It may not be compatible with that game.Try get a different cart (Look on the link).
