Emulator Problem: Problem with BGB emulator!!

hello guys!
I want your advice please cause i'll go crazy!

I have downloaded the BGB emulator and i play the Legend of Zelda- Link's awakening for the old gameboy, the green-black screened.
I played for about 3 days. And yesterday started to act frustrating. When i quit the game it "forgets" where i quitted! First time i had to do all the 2 quests i had finished, from the begining. Today it remembered i had done only half of the first quest and the second not at all.
What can i do???? I have done the quests 2 times already, i can't do this all the time!

The funny-frustrating thing is that i had this game original when i had my gameboy as a kid. And it had a problem too, it forgot aaaaaaaaall the saves at the last dungeon!!!!! i had tried to finish it 4 times but all the 4 times the same happened....at the last dungeon all saves where lost.

When i found it, before some days, i was so happy to finish it at last after so many years!!! and now...the same thing is happening and i'm going crazy!!!!!!!!!!!!
Please help me!!!!!! :msn_cry::msn_cry::msn_cry:
