Problem with Final Fantasy Tactics Advance
 

I have an Extreme 512Mbit Card that won't let me save my game while playing FFT-A, so I figured I needed a patch, and started looking for one, but I can't find one anywhere, then I downloaded GBAUtil and GUI and entered all the info they asked for, but nothing happened, the file was not patched (since it still is not working on my Card).

What am I doing wrong?
How do I fix this?
