2 game problems please help

hello everyone, please i really need your help iive searched everywhere for a fix but found nothing.

1) my first problem is that advance wars dual strike (e) wont save. I am using EZF advance III 256m gba flash cart, flashme 7. I have patched the rom using loadme to .nds.gba with sram ticked, the game works fine but doesnt save.

2) Lost magic (e) wont work on my ds at all. I patch it to .nds.gba with sram on, flash it on my ezf advance III, then when i turn the ds on, the top screen stays white, and the bottom screen stay black, why is it doing this. Please help, thankyou!
