Open the Radio Tower takeover, Ice Path, Blackthorn and Dragon's Den (#32)

The Rocket-held Radio Tower, the Underground's switch room and warehouse,
Ice Path, Blackthorn City and its gym, Routes 45 and 46, Dark Cave's
Blackthorn entrance, Dragon's Den and the Dragon Shrine are open. The story
plays through the Basement Key, the switches and the director, the Clear
Bell, Ice Path's falling boulder, Clair's gym and the shrine's test for the
RISINGBADGE, TM24 and the elder's Dratini.

New specials: GiveDratini and MoveDeletion. A save keeps an object that a
script made disappear (or appear against its flag) as Continue does, so the
Radio Tower director no longer blocks the 5F stairs after a reload. A
whiteout from a battle started in an scall no longer refuses.

The playthrough driver pushes boulders into their holes (planned breadth
first), clears whirlpools, chooses the move a TM replaces and heals with
the strongest potion; the run gains six stages to the Rising Badge.
