No$GBA Emulator Problems Pokemon Sapphire

[BKBitar]

Whenever I go to some areas of the game a like gray screen takes over the screen rather than what's supposed to be there. This has happened at Mt Pyre, the Fire Gym, and now whenever I dive. I was able to get through it when I was at Mt. Pyre and the Fire Gym, but I simply can't do it with the diving. Does anyone know how to fix this problem?

But then how do I load my save from the no$gba emulator?
