.sav files are gone?

I'm using VBA-M for OS X, and recently I noticed that my .sav files are gone. My game saves still load, but they don't seem to be in the folder anymore. And they only load with VBA-M now... If I open it in another emulator it starts like new.

So what's going on here? It seems to be storing the saves itself, but I can't seem to find where it's putting them.

EDIT: Same goes for KiGB. What the heck is going on?!

EDIT AGAIN: Nevermind, I figured it out. (Username)/Library/Application Support/VBA-M/Battery Saves
KiGB saves are also in Application Support... anyway yeah. :p

For the starting new problem, when you open a .sav in a different emulator, chances are, the .sav will not work. It is because different emulators save differently.
