+//  line. 00.14c steps up onto (9, 6) and talks to Misty from beside her.
+//
+//  Misty beat a Lv20 Wartortle (console B, run m51), so first a GRIND to
+//  Lv23 on 00.15's patch. Gen 3 numbers (pokefirered: her mons have IV 0;
+//  Wartortle taken at IV 15, no EVs): Starmie Lv21 has 56 HP, Atk 36, SpA
+//  47, SpD 40. Bite is Dark, special in Gen 3, no STAB, x2 on Psychic: at
+//  Lv23 (SpA 39) it does 23..28, three hits (two on top rolls); at Lv20,
+//  20..24. Her Swift (physical, 60) does 9..11 to a Lv23 Wartortle (about
+//  67 HP, Def 45) and Water Pulse (STAB, resisted) 8..10: 6 or more hits,
+//  though m51 saw about 20 a turn. Her Recover (28) and Super Potion undo
+//  a Bite, so the margin is in Bite's damage.
+//
+//  The Mart comes before the GRIND: its wild battles are fought only with
+//  2 or more Potions, and 00.14's save has none (m51 met Misty with only
+//  the 5 this row bought). 5 Potions (row 3, 300 each), then up to 3 Super
+//  Potions (row 2, 700), last so they take the Items pocket's last row;
+//  the battle doesn't use them yet. The money box can't be read, so the
+//  floor stands for it, and a floor above the money fails the step (the
+//  quantity box wraps). Prizes (pokefirered: 4 x last level x the class's
+//  factor) from a new game's 3000, less Viridian's 2000 and the Magikarp's
+//  500: Liam 220, Brock 1400, Route 3's bug catchers 360, the Mt. Moon
+//  grunt 416 and Miguel 288 (the first rival's 80 only if won), at least
+//  3184 here. Floor and budget 3000: 5 Potions and 2 Super Potions, 2900.
+//  Misty's 2100 (4 x 21 x 25) then leaves 00.15 its floor of 1500. Then the
