Conversion of .gsv to .sav for vba

I am using the vba emulator version 1.8.0 beta 3 and have downloaded a save game for lufia - the ruins of lore from the gameshark website.
However the game save will not work duew to the file format. T
he save game is a .gsv file when I need .sav, I have also downloaded a file trimmer but still cannot get it to work.
Can someone please help me with directions on how to get the file to work?

Thanks Seph, but I keep getting Internet Explorer cannot display the webpage. I think their download link may be broken as I have tried it in several browsers.

Can anyone please help me with this?
