VBA problems

I'm using VBA 1.7.2, but i can't run pokemon ruby, sapphire or diamond, is it the version problem? Is there any other emulator that works? Is there any recommended sites to download the roms?

This question has been answered before, try using the forums search function.

They should work.
Pokemon diamond won't work because it is a nds rom.
Try it with no$gba.

Well actually, it depends which Pokemon Diamond he is talking about! There's a fake version on VBA. It's so funny. You can call Pokemon by using a phone. You have to dial their number. Lol!! :D
