NDS .SAV File Reader Needed - 50 odd files w. no names to tell the game its from

Basically I have a ton of recovered files which all have the .CHK extension and file0001 etc, i've figured out which are likely to be sav files by the size and renamed them, but i don't know which is for which game.Is there any ultility or save game reader that would be able to identify which game each .sav file is for?
