emulation on a 360???

does anyone know if its possible to run the emulators on an xbox 360, like from a flash drive, do i have to mod it and if so which one (dont know anything about modding a 360) or if theres a way i can hook my xbox up to my computer so i can be using my xbox, but some how use the emulators or videos from my computer on my 360???
 
actually i have tried that but for some reason my controller wont sync with my pc...idk, that and i was just seeing the extents of what could be done, my friend wants to mod his 360 so it got me a little interested because i havnt heard of modding a 360 a whole lot, so i thought id ask some questions about emulations on the 360 cuz nothins better on a rainy day then chillin and playing some games i havnt played since i was like 8
