Open Routes 35 to 37, the National Park and Ecruteak to the Fog Badge (#32)

Enable Route 35, Route 36, Route 37, the National Park and its gates,
Ecruteak City and its buildings, the Tin Tower entrance, the Wise Trio's
room and both floors of the Burned Tower. The story runs from Floria,
the SquirtBottle and Sudowoodo through the Kimono Girls' HM03 Surf, the
rival in the Burned Tower and the beasts' release to Ecruteak Gym,
Morty, the FOGBADGE and TM30.

Port roaming Pokémon (InitRoamMons, UpdateRoamMons, JumpRoamMons,
CheckEncounterRoamMon) with their state in the save; only Continue moves
them on restore, so a failed import's rollback keeps them in place.
Port the Bug-Catching Contest: registration on contest days, Park Balls,
contestants, the timer, QUIT, the catch-and-swap prompt, judging from
the ROM's contestant table, prizes and the saved contest state.

Port the Game Corner's SlotMachine and CardFlip on a new realtime tile
screen that advances two frames per tick with buffered buttons: reel
strips and scrolling, bias tables, the seven streak, Golem and Chansey,
payouts, the Card Flip board, cursor and navigation. Their tilemaps are
checked against the ROM's own data.

Also port getnum, a plain warp that continues its script on the new map,
and PokemonNames' EGG entry. A trainer whose script is ObjectEvent (the
Burned Tower rival) is no longer sighted once its own flag is set, as
the original's read of bit 1 of wNumKeyItems gives with the usual key
items.

The playthrough walks through the National Park and continues to Morty;
its driver chooses moves by type matchup, buys at Marts and uses Super
Potions and Awakenings in trainer battles. New tests cover roaming, the
contest, the Game Corner and Ecruteak's side content.

 Walk around your home, the town and its buildings at the original walking speed. Mom gives you the Pokégear and asks the day of the week. The teacher stops you from leaving town. Your rival shoves you away from the lab window. Professor Elm introduces his errand, and you choose Chikorita, Cyndaquil or Totodile. The Pokémon's picture and stats come from your ROM, and you can nickname it. Elm's aide then gives you a Potion. These scenes run the game's own event scripts and movement data, with native choices and naming.

Kurt makes balls from apricorns overnight. In the Ruins of Alph, solve the chamber puzzles to unlock wild Unown, which appear in their letters and fill the Unown Dex.

On Tuesdays, Thursdays and Saturdays, enter the Bug-Catching Contest: catch the best bug you can with the Park Balls before time runs out, then wait for the judging and the prizes. Water the odd tree on Route 36 with the SquirtBottle from Goldenrod's flower shop, then follow Route 37 to Ecruteak City. Beat the five Kimono Girls in the Dance Theater for HM03 Surf. In the Burned Tower, your rival challenges you before the floor gives way and three legendary Pokémon flee; Raikou and Entei then roam Johto's routes, where you may meet them in the grass. Morty is then back in his gym for the Fog Badge.
