I recently downloaded VBA and Pokemon Emerald. The game says "The Internal Battery has run dry" I've been told to go to Options>Emulator>Real Time Clock, but there is no clock! I have checked everywhere and tried multiple other fixes, but nothing works!
Try running it from the terminal.
vba --rtc yourromfile.gba
If it works, there must be something wrong with your configuration in the graphical version. You can play with it more or just start running VBA from the terminal.
If you want a full list of options you can give VBA, type
man vba. There's more stuff in there than in the graphical version.
