Tell me what to do

For DeSmuME

File Open and load the game
File > Import Memory Backup > Open the sav > and then check AUTO (ADCANsCEne Database) and hit OK

Game will reload and have Continue & Load there

Export would be raw, but you can test that after you backup the original save that you already have done by uploading it

EDIT if you want me to look at this at least save at the end of the fight
