Pokemon Ruby/ Sapphire/ Emerald Load failure

??? Hi guys, i have this problem about the above mentioned versions of Pokemon with my visual boy advance. i already downloaded them from almost all of the websites in google and yahoo that offers free download but it appears that as soon as i open them in my vba, the screen goes white and stays white till i get damn annoyed that i just shut it down... if someone could please tell me what this problem is and how to solve it, i would really appreciate it. :) thanks in advance.*btw, i also downloaded Pokemon emerald from this exact site but unfortunately it also didn't work... :'(
