This is a Gameshark save file (.sps), and can be loaded into VBA, or any other GBA emulator, but I can't seem to get it to work.
The description says the game is 95% completed, everything purchased, and lots of studs. This can be useful on single stage runs, or practice you want to do when you don't have a 100% completed file. 
Because of how this is a Gameshark save file, you might be able to use on real hardware, though I'm not sure how to import Gameshark save files.
