VBAGX save file question

Does anybody know if the save files produced by the VBAGX are able to be recognized and used by any GBA emulator on the computer?

I'd assume that since VBAGX is based of the VBA emulator, that the saves would be compatable, but I'm just guessing.

I just tried this yesterday. The state saves are not compatible (the file with extension .sgm or something like that) even with the latest version of VBA (for me at least). The battery file (with extension .sav) should be compatible with absolutely any GameBoy emulator. This is a bit old but... maybe I helped someone else.
