XBox 360 emulation questions?

Hi all, new here.

I bought all my fav games from all the old consoles & would love to be able to back them up & play them on an XBox 360 emulating SNES & N64.
How can I run an emulator on an XBox 360 , do I need to mod the XBox 360? What is the safest cheapest way to do this or what is the expensive best way?

I also bought my fav XBOX 360 games, but hate having to swap the damn discs each time. I would love to also install the games on the XBox 360 HD and run them directly.

So what is the best way to Emulate & play 360 games off of HD?

Also, once I mod it can I go online with normal account? I guess I could give up one xbox for this convenience.


Is something like this mod all that I need & is it a good one?
