1-M sub-circuit board is not installed o.O

I get this error on VBA when after the "press start" screen on FireRed.What can I do about it? =|

it means that game requires additional hardware that is not being emulated. It may not be possible to emulate that game.

Hmm, All the pokemon games worked fine on my VBA.
What version are you using?While you are at it, take a look at this thread and follow the instructions:

You'll specifically need the vba-over.ini file in the VisualBoyAdvance directory for this to work.
