Help with Save corruption

I have an R4 card (Not sure if clone or not but it runs the Wood 1.51 kernel perfectly as well as I can tell) and a EZ Flash V 3-in-1 card.I have no problem with playing any GBA games...but I am having a problem with save corruption.
If I switch between any 2 GBA games the saves for both become corrupt and deleted as soon as I load up the other one.
Specific Example: If I play Metroid Fusion, save, then load up Pokemon Fire Red, the Fusion save data will be corrupt as soon as I play it again. Then the Fire Red save will be gone when I attempt to play that again.I would love to have some help with this problem.
Thanks.

The only thing that I've come to discover is that this might be "working as intended" since the EZ Flash cards can only hold one GBA game at a time.I tried using GBA Exploader and still was unable to switch between GBA games without losing my saves.Anybody able to shine some light on this?
