Im having a small problem. Please help a noob

[Dillsandwitch]

I have a visualboy advance version 1.8.0-beta and im having problems with the battery file. When it starts it says the batteryfile is loaded but when the game starts it says the internal battery has run dry and that clock based features cannot be used. It kinda defets the purpose if you cant play the game properly and Ive googled battery files but cant find anything helpfull.

Please help out a noob and there be cookies in it for you. :)

Thanks in advance
Dill
