It have nothing to do with emu. It just write something to the windows directory and you run the no$gba..too complicate. Just go to windows directory and find Prefetch folder and look for no$gba.pf file then remove it and remove your no$gba directory and redownloading it and run your brand new no$gba like a first time to see what's happening. If you still have the same problem then you are in trouble.
EDIT: 900 ?! Let's partying and all of you people are invited!
