The official pages for the emulators are
NES http://xport.xbox-scene.com/
SNES http://www.lantus-x.com/xSnes9x/
GBA http://90-26x.port5.com/
They have the info you need,but not the emulators.
You see microsort says they are illigal we can't give any links.
If you search for the program's name in a search engine or in a P2P program you will find them.
