- Backing up no longer asks for the key combo, just a button press, since reading a cart can't damage it
- Mistyping the key combo now offers a retry instead of silently starting over
- The startup and confirmation screens now warn about the risks before you back up or write
- Confirmation screens are centred and spaced out, so they're easier to read
- Every key combo prompt now gets a different sequence (two prompts in the same second used to get an identical one)
- When a cart can't be detected, the log now records why, making bug reports more useful
- The README now documents the real steps, the supported carts, and how to report a problem
