Pokemon Emerald Save&Exit

Whenever I play pokemon emerald, and I save and exit, I am unable to run the game again. My No$gba emulator is always "Not Responding" after I exit it. I can play the game, but am unable to re-enter it once I exit it the first time.
Anyone have the same problem?

Although no$gba support GBA games, it was highly recommended to play it on GBA emulator, such as VisualBoy Advance.

When using visual boy advance, be sure to set the save type to FLASH 128k, or the same problem will occur
