[NDS] games save but don't load..

help! i've got some games on my r4i SDHC Upgrade v1.4 that don't seem to be saving..whenever i'm playing the autosave comes up, so does the saving message when I do it manually.
but the next time i load the game it comes up at the New Game screen again..this has been happening to the ff of my games: My Japanese Coach and Digimon World Championship..
all my other games' save files are loading properlyhope someone could shed some light on this :D thanks in advance!

Just save it with the In-Game save option.
