Console Game Downloads

Hey I’m new here and I was wondering.. if you downloaded console games would that mean I need to burn it to a disc or something to play it on the console or can it be played off of my computer?
Ex. Download Naruto Broken Bonds console game for Xbox, how would you play it? Do you need an emulator, can you just play it on the computer or it must be burned onto a disc for the console or what?
Just want to get the idea down, thanks!
**Sorry if something like this is asked already
Answer #1
No Xbox 360 emulator exists for the PC.
Depending on how your xbox 360 is modified, that will determine how you would play the game.
DVD Drive flashed with modded firmware – Disc needs to be burned.
JTAG Console – External Hard drive
Xbox 360 Emulation device such as Xk3y – External Hard drive.
That pretty much sums it up.
Answer #2
as said above there is no current gen emulators
u gotta modify ur xbox as stated above
