So, I didn't bring up Xbox earlier, because Microsoft has an official way to run homebrew on Xbox consoles.
All modern Xboxes have access to something called developer mode. This allows people to put whatever code they like on it, but removes the ability to play retail games. The change isn't permanent, however, and switching between the modes is perfectly safe.
This is a big part of the reason why Xbox 1 never had piracy; pirates couldn't piggyback on the back of homebrewers, who simply opted to use developer mode instead of cracking the console.
