How can I move my Mass Effect 2 save between Xboxes?

I'm wondering if I can start up my most recent Mass Effect 2 save file on my old system, make a save to my flash drive, load the game from the flash drive on my new Xbox,

You can do this:

  1. Use the Memory tool on the old xbox to copy your ME2 save to your flash drive.
  2. Use the Memory tool on the new xbox to copy your ME2 save from the flash drive.

This should work with both playable and endgame ME2 saves.

Note: you may need to move your gamertag as well.
