Cant get Final Fantasy XII Revnant Wings to save

So I downloaded the ROM from here and it will play on my NDS but everytime I try to save the game, after it saves the game, It says Save File is Corrupted and Deletes the file.How can I fix this so that I can save the game and it will stay saved.

got newest No$GBA and No$Zoomer and i dunno what card since its a Emulatorhave also tried changing the backup memory or w/e its called and none seem to work. Everytime i save game, it will say save successful, and then say save file corrupted and deletes the save.

no$gba 2.6a and no$zoomer.
The back-up for nds is Auto and it should work fine.I have no saving problems with this game.

Get a fresh copy for both emulator and addons,
put it into a same folder,
and run it again.there should be no problem with this game while playing on no$gba2.6a.

ok so redownload the game?and what else, new to using emulators and such.
