Xbox controller

The larger original controller remained available as an optional accessory and was rereleased for the Xbox One after fans requested it back.

Seamus Blackley was a video game developer for Xbox and helped design an early prototype controller.

[11] Over fifteen years later Seamus Blackley contacted Phil Spencer, the head of the Xbox division, and pitched an idea to revive the old controller, following a series of joking posts through social media that showed strong consumer desire for the controller.

Most Xbox game saves can be copied to the memory unit and moved to another console but some Xbox saves are digitally signed; each console has a unique signing key, and some games (e.g. Ninja Gaiden and Dead or Alive Xtreme Beach Volleyball) will not load saved games signed by a different Xbox, limiting the utility of the memory card.

Some game saves can be tagged as uncopyable (like Burnout 3: Takedown) or simply padded to over 8 MB (Star Wars: Knights of the Old Republic).

The signing mechanism has been reverse-engineered by the Xbox hacking community, who have developed tools to modify savegames to work in a different console, though the signing key of the recipient Xbox (the "HDkey") and the ramped-up title key of the game (the "authkey") must be known.

The Xbox controller features breakaway dongles to avoid damage to the console if the cord is tripped over.
