tools: let the submenu sweep target NEW GAME, for the DIFFICULTY reset question

DIFFICULTY opens on NORMAL, the second of four, so it is the screen that separates
'resets to the named item' from 'resets to the top item' -- the question
sylpheed-port has had open for several iterations.

The probe is safe on this path without modification: it presses A to enter, one
DOWN, then B to leave, and never presses A inside a submenu, so it cannot reach
SELECT DATA and the guest throw at PC 0x82307128. Noted in the source so nobody
adds one.
