trouble saving in Golden sun for GBA on M3

For some reason I can't save my game file for Golden Sun, but I can save my game files for Pokemon FireRed and Fire Emblem. Can anyone help me out with this? I tried redownloading and that still doesn't work.

Re-downloading a working game won't work.I am guessing you tried removing the game and it's save and putting the rom back in without the save?

What firmware version?

no, i completely redownloaded another golden sun game, and then put it on the card. I'm using the M3 Sakura firmware.
