using saved file on an nes game

i have baseball stars on my ds. i used the dnester emulator. i am having trouble using the data i have saved from the game. i looked on the sd card and there is a .sav for it. I am not sure if there is a way to access it though.
any help would be appreciated.

What are you wanting to do with the save file?

i want the game to recognize it. whenever i turn the game off and then turn it back on, the game doesnt have any of the saved files.

I had the same problem, never did find out if there was a way to resume my saved game once I powered off and then back on.

anyone? anything?
