How can you save your progress on a Pokémon rom for VisualBoy Advance? - visualboy advance silver

I recently downloaded a game Boy Emulator for Mac OSX Visualboy called play Game Boy Advance to on my computer. He downloaded an emulator for Pokemon Silver. Both programs work very well. Every time I try, is to save my progress throughout the game, said to save my progress, but when I open the program again to continue playing my game is saved, is not available and I have to start from scratch. Is there a way to actually save your progress and can then turn left and continue after a break?
