# Section 19 - S.S. Aqua and Vermilion City Gym

Source: `../section-19-s-s-aqua-and-vermilion-city-gym.txt`
Maps covered: `NEW_BARK_TOWN`, `ELMS_LAB`, `OLIVINE_PORT_PASSAGE`, `OLIVINE_PORT`,
`FAST_SHIP_1F`, `FAST_SHIP_CABINS_NNW_NNE_NE`, `FAST_SHIP_CABINS_SW_SSW_NW`,
`FAST_SHIP_CABINS_SE_SSE_CAPTAINS_CABIN`, `FAST_SHIP_B1F`, `VERMILION_PORT`,
`VERMILION_PORT_PASSAGE`, `VERMILION_CITY`, `POKEMON_FAN_CLUB`, `VERMILION_GYM`
Badges / key milestones in this section: S.S. TICKET from Prof. Elm, first Kanto
crossing on the Fast Ship, METAL COAT from the grandpa on the S.S. Aqua,
`ENGINE_FLYPOINT_VERMILION`, RARE CANDY from the Fan Club Chairman,
**THUNDERBADGE** (`ENGINE_THUNDERBADGE`) from Lt. Surge.

This section begins immediately after the Hall of Fame. `maps/HallOfFame.asm`
`HallOfFameEnterScript` is what arms it: it sets `EVENT_BEAT_ELITE_FOUR`, sets
`EVENT_OLIVINE_PORT_SPRITES_BEFORE_HALL_OF_FAME` (hiding the "no entry" sailor
pair), clears `EVENT_OLIVINE_PORT_SPRITES_AFTER_HALL_OF_FAME` (revealing the
boarding sailor), and, if `EVENT_GOT_SS_TICKET_FROM_ELM` is still clear, queues
`specialphonecall SPECIALCALL_SSTICKET` (the Elm call the walkthrough mentions).

## 1. Route order

| # | Map constant | asm file | Enter via | Leaves via | Why (walkthrough beat) |
|---|---|---|---|---|---|
| 1 | `NEW_BARK_TOWN` | `maps/NewBarkTown.asm` | post-credits respawn | warp 1 `(6,3)` -> `ELMS_LAB` 1 | Elm phones you to come back |
| 2 | `ELMS_LAB` | `maps/ElmsLab.asm` | warp 1/2 `(4,11)`/`(5,11)` | same warps back to `NEW_BARK_TOWN` 1 | talk to `ProfElmScript` -> `ElmGiveTicketScript` -> S.S. TICKET |
| 3 | `OLIVINE_CITY` | `maps/OlivineCity.asm` | Fly (`ENGINE_FLYPOINT_OLIVINE`) | warp 10 `(19,27)` / warp 11 `(20,27)` -> `OLIVINE_PORT_PASSAGE` 1/2 | "go south from the Pokemon Center" to the port entrance |
| 4 | `OLIVINE_PORT_PASSAGE` | `maps/OlivinePortPassage.asm` | warps 1/2 `(15,0)`/`(16,0)` | warp 3 `(15,4)` -> warp 4 `(3,2)`, then warp 5 `(3,14)` -> `OLIVINE_PORT` 1 | "take the stairs down twice" |
| 5 | `OLIVINE_PORT` | `maps/OlivinePort.asm` | warp 1 `(11,7)` | coord_event `(7,15)` -> `OlivinePortWalkUpToShipScript` -> `warp FAST_SHIP_1F, 25, 1` | show the S.S. TICKET, board |
| 6 | `FAST_SHIP_1F` | `maps/FastShip1F.asm` | scripted warp to `(25,1)` | 12 warps (see below) | ship deck hub; grandpa bumps you at `(24,6)`/`(25,6)` |

| 10 | `FAST_SHIP_B1F` | `maps/FastShipB1F.asm` | 1F warps 11/12 (`(6,12)`, `(30,14)`) | same | on-duty sailor blocks; Fritz, Jeff, Debra |
| 11 | `VERMILION_PORT` | `maps/VermilionPort.asm` | `FastShip1FSailor1Script` -> `warp VERMILION_PORT, 7, 17` | warp 1 `(9,5)` -> `VERMILION_PORT_PASSAGE` 5 | ship docks in Kanto |
| 12 | `VERMILION_PORT_PASSAGE` | `maps/VermilionPortPassage.asm` | warp 5 `(3,14)` | warp 4 `(3,2)` -> warp 3 `(15,4)`, then warps 1/2 `(15,0)`/`(16,0)` -> `VERMILION_CITY` 8/9 | "down the stairs, then up the stairs and out the door" |
| 13 | `VERMILION_CITY` | `maps/VermilionCity.asm` | warps 8/9 `(19,31)`/`(20,31)` | warp 3 `(7,13)`, warp 7 `(10,19)` | first look at Kanto |

Spill-over note: the walkthrough's closing line ("Congrats on your first badge in
Kanto") ends the section; Saffron City / Route 6 are handled by the next
section's agent. `VERMILION_CITY` connects `north Route6 (+5)` and
`east Route11 (0)` (`data/maps/attributes.asm:342-344`), and warp 10 `(34,7)` to
`DIGLETTS_CAVE` sits behind the sleeping Snorlax; none of those are used here.

## 2. Maps

### MAP_ELMS_LAB

- Script: `maps/ElmsLab.asm`
- Blocks: `maps/ElmsLab.blk`
- Header: `data/maps/maps.asm:476` -> `map ElmsLab, TILESET_LAB, INDOOR, LANDMARK_NEW_BARK_TOWN, MUSIC_PROF_ELM, FALSE, PALETTE_DAY, FISHGROUP_SHORE`
- Dimensions: `constants/map_constants.asm:441` `map_const ELMS_LAB, 5, 6` (10 x 12 cells)
- Connections: none (indoor)

Only the S.S. TICKET beat is in scope. Full warp/object tables for the early-game
scenes belong to section 1; the rows below are the ones this section touches.

**Warps** (`def_warp_events`)

| idx | x | y | destination map | dest warp |
|---|---|---|---|---|
| 1 | 4 | 11 | `NEW_BARK_TOWN` | 1 |
| 2 | 5 | 11 | `NEW_BARK_TOWN` | 1 |

**Object events** (`def_object_events`) - relevant row only

| const | sprite | x | y | movement | type | script label | event flag |
|---|---|---|---|---|---|---|---|
| `ELMSLAB_ELM` | `SPRITE_ELM` | 5 | 2 | `SPRITEMOVEDATA_STANDING_DOWN` | `OBJECTTYPE_SCRIPT` | `ProfElmScript` | `-1` |

**Scripts of interest**

- `ProfElmScript` (`maps/ElmsLab.asm:50`, sym `60:427b` for `ElmGiveTicketScript`).
  First two opcodes after `faceplayer`/`opentext` are the ticket gate:
  `checkevent EVENT_GOT_SS_TICKET_FROM_ELM` / `iftrue ElmCheckMasterBall`, then
  `checkevent EVENT_BEAT_ELITE_FOUR` / `iftrue ElmGiveTicketScript`. So the ticket
  is handed out on the first post-Hall-of-Fame conversation and never again.
- `ElmGiveTicketScript`: `writetext ElmGiveTicketText1` ->
  `verbosegiveitem S_S_TICKET` -> `setevent EVENT_GOT_SS_TICKET_FROM_ELM` ->
  `writetext ElmGiveTicketText2` -> `closetext` / `end`.
  Note there is **no** `iffalse` bag-full guard on this `verbosegiveitem`, unlike
  every other Elm gift in the same file - the flag is set unconditionally.
- `engine/phone/scripts/elm.asm:69` `ElmPhoneCallerScript` routes
  `SPECIALCALL_SSTICKET` to `.gift`, which prints `ElmPhoneGiftText` and clears
  the pending call with `specialphonecall SPECIALCALL_NONE`. The call is only the
  nudge; it does not give the item.

**Flags and events**

| constant | defined in | read/written by | meaning for a bot |
|---|---|---|---|
| `EVENT_BEAT_ELITE_FOUR` | `constants/event_flags.asm:77` | set by `maps/HallOfFame.asm:33`; read by `ProfElmScript` | precondition for the ticket |
| `EVENT_GOT_SS_TICKET_FROM_ELM` | `constants/event_flags.asm:45` | set by `ElmGiveTicketScript`; read by `ProfElmScript` and `HallOfFame.asm:41` | one-time ticket guard |
| `SPECIALCALL_SSTICKET` | `constants/phone_constants.asm:49` | queued by `HallOfFame.asm:43`, consumed in `engine/phone/scripts/elm.asm` | the phone nudge; ignorable |

**Items**

| item | how obtained | source (label / bg_event / hidden) | one-time flag |
|---|---|---|---|
| `S_S_TICKET` | talk to Elm | `ElmGiveTicketScript` `verbosegiveitem S_S_TICKET` | `EVENT_GOT_SS_TICKET_FROM_ELM` |

### MAP_OLIVINE_PORT_PASSAGE

- Script: `maps/OlivinePortPassage.asm`
- Blocks: `maps/PortPassage.blk` (shared with `VermilionPortPassage`; there is no
  `OlivinePortPassage.blk`)
- Header: `data/maps/maps.asm:340` -> `map OlivinePortPassage, TILESET_UNDERGROUND, INDOOR, LANDMARK_OLIVINE_CITY, MUSIC_VIOLET_CITY, FALSE, PALETTE_DAY, FISHGROUP_SHORE`
- Dimensions: `constants/map_constants.asm:314` `map_const OLIVINE_PORT_PASSAGE, 10, 9` (20 x 18 cells)
- Connections: none

**Warps** (`def_warp_events`)

| idx | x | y | destination map | dest warp |
|---|---|---|---|---|
| 1 | 15 | 0 | `OLIVINE_CITY` | 10 |
| 2 | 16 | 0 | `OLIVINE_CITY` | 11 |
| 3 | 15 | 4 | `OLIVINE_PORT_PASSAGE` | 4 |
| 4 | 3 | 2 | `OLIVINE_PORT_PASSAGE` | 3 |
| 5 | 3 | 14 | `OLIVINE_PORT` | 1 |

**Coord events** - none.

**BG events** - none.

**Object events** (`def_object_events`)

| const | sprite | x | y | movement | type | script label | event flag |
|---|---|---|---|---|---|---|---|
| `OLIVINEPORTPASSAGE_POKEFAN_M` | `SPRITE_POKEFAN_M` | 17 | 1 | `SPRITEMOVEDATA_STANDING_LEFT` | `OBJECTTYPE_SCRIPT` | `OlivinePortPassagePokefanMScript` | `EVENT_OLIVINE_PORT_PASSAGE_POKEFAN_M` |

The Pokefan is hidden at new game (`InitializeEventsScript`,
`engine/events/std_scripts.asm:530` sets the flag) and revealed by
`VermilionPortLeaveShipScript` (`clearevent EVENT_OLIVINE_PORT_PASSAGE_POKEFAN_M`)
once you have made the crossing once. His text is the Monday/Friday schedule.

### MAP_OLIVINE_PORT

- Script: `maps/OlivinePort.asm`
- Blocks: `maps/OlivinePort.blk`
- Header: `data/maps/maps.asm:333` -> `map OlivinePort, TILESET_PORT, ROUTE, LANDMARK_OLIVINE_CITY, MUSIC_VIOLET_CITY, FALSE, PALETTE_AUTO, FISHGROUP_OCEAN`
- Dimensions: `constants/map_constants.asm:307` `map_const OLIVINE_PORT, 10, 18` (20 x 36 cells)
- Attributes: `data/maps/attributes.asm:586` `map_attributes OlivinePort, OLIVINE_PORT, $0a` - no connections

**Warps** (`def_warp_events`)

| idx | x | y | destination map | dest warp |
|---|---|---|---|---|
| 1 | 11 | 7 | `OLIVINE_PORT_PASSAGE` | 5 |
| 2 | 7 | 23 | `FAST_SHIP_1F` | 1 |

**Coord events** (`def_coord_events`)

| scene | x | y | script label | effect |
|---|---|---|---|---|
| `SCENE_OLIVINEPORT_ASK_ENTER_SHIP` (0) | 7 | 15 | `OlivinePortWalkUpToShipScript` (sym `5b:407d`) | boarding prompt + ticket check |

**BG events** (`def_bg_events`)

| x | y | type | script/item |
|---|---|---|---|
| 1 | 22 | `BGEVENT_ITEM` | `OlivinePortHiddenProtein` -> `hiddenitem PROTEIN, EVENT_OLIVINE_PORT_HIDDEN_PROTEIN` |

**Object events** (`def_object_events`)

| const | sprite | x | y | movement | type | script label | event flag |
|---|---|---|---|---|---|---|---|
| `OLIVINEPORT_SAILOR1` | `SPRITE_SAILOR` | 7 | 23 | `SPRITEMOVEDATA_STANDING_UP` | `OBJECTTYPE_SCRIPT` | `OlivinePortSailorAtGangwayScript` | `EVENT_OLIVINE_PORT_SAILOR_AT_GANGWAY` |
| `OLIVINEPORT_SAILOR2` | `SPRITE_SAILOR` | 7 | 15 | `SPRITEMOVEDATA_STANDING_UP` | `OBJECTTYPE_SCRIPT` | `OlivinePortSailorBeforeHOFScript` | `EVENT_OLIVINE_PORT_SPRITES_BEFORE_HALL_OF_FAME` |
| `OLIVINEPORT_SAILOR3` | `SPRITE_SAILOR` | 6 | 15 | `SPRITEMOVEDATA_STANDING_RIGHT` | `OBJECTTYPE_SCRIPT` | `OlivinePortSailorAfterHOFScript` | `EVENT_OLIVINE_PORT_SPRITES_AFTER_HALL_OF_FAME` |
| `OLIVINEPORT_FISHING_GURU1` | `SPRITE_FISHING_GURU` | 4 | 14 | `SPRITEMOVEDATA_STANDING_UP` | `OBJECTTYPE_SCRIPT` | `OlivinePortFishingGuru1Script` | `EVENT_OLIVINE_PORT_SPRITES_BEFORE_HALL_OF_FAME` |
| `OLIVINEPORT_FISHING_GURU2` | `SPRITE_FISHING_GURU` | 13 | 14 | `SPRITEMOVEDATA_STANDING_UP` | `OBJECTTYPE_SCRIPT` | `OlivinePortFishingGuru2Script` | `EVENT_OLIVINE_PORT_SPRITES_BEFORE_HALL_OF_FAME` |
| `OLIVINEPORT_YOUNGSTER` | `SPRITE_YOUNGSTER` | 4 | 15 | `SPRITEMOVEDATA_STANDING_DOWN` | `OBJECTTYPE_SCRIPT` | `OlivinePortYoungsterScript` | `EVENT_OLIVINE_PORT_SPRITES_AFTER_HALL_OF_FAME` |
| `OLIVINEPORT_COOLTRAINER_F` | `SPRITE_COOLTRAINER_F` | 11 | 15 | `SPRITEMOVEDATA_STANDING_DOWN` | `OBJECTTYPE_SCRIPT` | `OlivinePortCooltrainerFScript` | `EVENT_OLIVINE_PORT_SPRITES_AFTER_HALL_OF_FAME` |

Object event flags hide when **set**. Post-Hall-of-Fame, `SAILOR2` and the two
fishing gurus are gone and `SAILOR3` / youngster / cooltrainer are present.

**Scripts of interest**

- `OlivinePortWalkUpToShipScript` (coord event at `(7,15)`): turns `SAILOR3`
  right, bails via `.skip` if either `EVENT_TEMPORARY_UNTIL_MAP_RELOAD_1` or
  `_2` is set, else asks `OlivinePortAskBoardText` with `yesorno`.
  If `EVENT_FAST_SHIP_FIRST_TIME` is **clear** it jumps straight past the
  weekday gate (`.FirstTime`) - the maiden voyage sails any day.
  Otherwise `readvar VAR_WEEKDAY`: `SUNDAY`/`SATURDAY` -> `.NextShipMonday`,
  `TUESDAY`/`WEDNESDAY`/`THURSDAY` -> `.NextShipFriday`. So from Olivine the ship
  sails **Monday and Friday**.
  Then `checkitem S_S_TICKET`; `iffalse .NoTicket`. On success it sets
  `EVENT_TEMPORARY_UNTIL_MAP_RELOAD_2`, walks the player 7 steps down
  (`OlivinePortApproachFastShipFirstTimeMovement`) and `sjump`s into
  `OlivinePortSailorAtGangwayScript`.
- `OlivinePortSailorAtGangwayScript`: `disappear OLIVINEPORT_SAILOR1`, one step
  down, `special FadeOutToWhite`, then the passenger-roster bookkeeping.
  On repeat trips only (`checkevent EVENT_FAST_SHIP_FIRST_TIME` / `iffalse
  .FirstTime`) it does `clearevent EVENT_FAST_SHIP_PASSENGERS_EASTBOUND`,
  `setevent EVENT_FAST_SHIP_PASSENGERS_WESTBOUND` and clears the eight
  eastbound `EVENT_BEAT_*` rematch flags. Always:
  `clearevent EVENT_FAST_SHIP_DESTINATION_OLIVINE`,
  `appear OLIVINEPORT_SAILOR1`,
  `setmapscene FAST_SHIP_1F, SCENE_FASTSHIP1F_ENTER_SHIP`,
  `warp FAST_SHIP_1F, 25, 1`.
- `OlivinePortLeaveShipScript` (scene `SCENE_OLIVINEPORT_LEAVE_SHIP`, 1): the
  arrival cutscene for the return trip - one step up, `appear` the sailor,
  `setscene SCENE_OLIVINEPORT_ASK_ENTER_SHIP`,
  `setevent EVENT_TEMPORARY_UNTIL_MAP_RELOAD_1`, `blackoutmod OLIVINE_CITY`.

**Wild encounters**

`data/wild/johto_water.asm:278` `def_water_wildmons OLIVINE_PORT`, encounter rate
`2 percent`: `20 TENTACOOL / 15 TENTACOOL / 20 TENTACRUEL`.
Fishing group `FISHGROUP_OCEAN` (`data/wild/fish.asm:13`, `.Ocean_*` at lines
42-55). No grass, no headbutt table.

### MAP_FAST_SHIP_1F

- Script: `maps/FastShip1F.asm`
- Blocks: `maps/FastShip1F.blk`
- Header: `data/maps/maps.asm:335` -> `map FastShip1F, TILESET_LIGHTHOUSE, INDOOR, LANDMARK_FAST_SHIP, MUSIC_SS_AQUA, FALSE, PALETTE_DAY, FISHGROUP_SHORE`
- Dimensions: `constants/map_constants.asm:309` `map_const FAST_SHIP_1F, 16, 9` (32 x 18 cells)
- Connections: none

Scene ids are declared inline by `scene_script` (`macros/scripts/maps.asm:25`):
`SCENE_FASTSHIP1F_NOOP` = 0, `SCENE_FASTSHIP1F_ENTER_SHIP` = 1,
`SCENE_FASTSHIP1F_MEET_GRANDPA` = 2.

**Warps** (`def_warp_events`)

| idx | x | y | destination map | dest warp |
|---|---|---|---|---|
| 1 | 25 | 1 | `FAST_SHIP_1F` | -1 (arrival tile only) |
| 2 | 27 | 8 | `FAST_SHIP_CABINS_NNW_NNE_NE` | 1 |
| 3 | 23 | 8 | `FAST_SHIP_CABINS_NNW_NNE_NE` | 2 |
| 4 | 19 | 8 | `FAST_SHIP_CABINS_NNW_NNE_NE` | 3 |
| 5 | 15 | 8 | `FAST_SHIP_CABINS_SW_SSW_NW` | 1 |
| 6 | 15 | 15 | `FAST_SHIP_CABINS_SW_SSW_NW` | 2 |
| 7 | 19 | 15 | `FAST_SHIP_CABINS_SW_SSW_NW` | 4 |
| 8 | 23 | 15 | `FAST_SHIP_CABINS_SE_SSE_CAPTAINS_CABIN` | 1 |
| 9 | 27 | 15 | `FAST_SHIP_CABINS_SE_SSE_CAPTAINS_CABIN` | 3 |
| 10 | 3 | 13 | `FAST_SHIP_CABINS_SE_SSE_CAPTAINS_CABIN` | 5 |
| 11 | 6 | 12 | `FAST_SHIP_B1F` | 1 |
| 12 | 30 | 14 | `FAST_SHIP_B1F` | 2 |

Warp 5 `(15,8)` is "your cabin" (the one with the healing bed). Warp 10 `(3,13)`
is the staircase to the captain's cabin.

**Coord events** (`def_coord_events`)

| scene | x | y | script label | effect |
|---|---|---|---|---|
| `SCENE_FASTSHIP1F_MEET_GRANDPA` (2) | 24 | 6 | `WorriedGrandpaSceneLeft` (sym `5b:495d`) | grandpa runs in and bumps you |
| `SCENE_FASTSHIP1F_MEET_GRANDPA` (2) | 25 | 6 | `WorriedGrandpaSceneRight` | `moveobject FASTSHIP1F_GENTLEMAN, 20, 6` then falls through into `WorriedGrandpaSceneLeft` |

**BG events** - none.

**Object events** (`def_object_events`)

| const | sprite | x | y | movement | type | script label | event flag |
|---|---|---|---|---|---|---|---|
| `FASTSHIP1F_SAILOR1` | `SPRITE_SAILOR` | 25 | 2 | `SPRITEMOVEDATA_STANDING_DOWN` | `OBJECTTYPE_SCRIPT` | `FastShip1FSailor1Script` | `-1` |
| `FASTSHIP1F_SAILOR2` | `SPRITE_SAILOR` | 14 | 7 | `SPRITEMOVEDATA_STANDING_RIGHT` | `OBJECTTYPE_SCRIPT` | `FastShip1FSailor2Script` | `-1` |
| `FASTSHIP1F_SAILOR3` | `SPRITE_SAILOR` | 22 | 17 | `SPRITEMOVEDATA_WALK_LEFT_RIGHT` (radius 2,0) | `OBJECTTYPE_SCRIPT` | `FastShip1FSailor3Script` | `-1` |
| `FASTSHIP1F_GENTLEMAN` | `SPRITE_GENTLEMAN` | 19 | 6 | `SPRITEMOVEDATA_STANDING_RIGHT` | `OBJECTTYPE_SCRIPT` | `ObjectEvent` | `EVENT_FAST_SHIP_1F_GENTLEMAN` |

**Scripts of interest**

- `FastShip1FEnterShipScript` (sym `5b:48ad`, scene 1, run via `sdefer`): sailor
  steps aside, player walks 2 down, sailor steps back and blocks the door,
  `playsound SFX_BOAT`, `earthquake 30`,
  `blackoutmod FAST_SHIP_CABINS_SW_SSW_NW` (your blackout respawn becomes your
  cabin), `clearevent EVENT_FAST_SHIP_HAS_ARRIVED`. Then
  `checkevent EVENT_FAST_SHIP_FIRST_TIME` / `iftrue .SkipGrandpa`: on the first
  crossing it sets `SCENE_FASTSHIP1F_MEET_GRANDPA`, otherwise
  `SCENE_FASTSHIP1F_NOOP`.
- `WorriedGrandpaSceneLeft`: `appear FASTSHIP1F_GENTLEMAN`, four `big_step RIGHT`,
  `playsound SFX_TACKLE`, knocks the player one step right,
  `writetext FastShip1FGrandpaText` ("My granddaughter is missing!"), then the
  gentleman runs off, `disappear`s and the scene is reset to
  `SCENE_FASTSHIP1F_NOOP`. Purely informational - it sets no quest flag.
- `FastShip1FSailor1Script` (the door guard at `(25,2)`): if
  `EVENT_FAST_SHIP_HAS_ARRIVED` is clear it just says "en route", branching on
  `EVENT_FAST_SHIP_DESTINATION_OLIVINE` for the destination name. Once arrived it
  runs `.LetThePlayerOut` (`readvar VAR_FACING`, two step-up variants), then
  `setevent EVENT_VERMILION_PORT_SAILOR_AT_GANGWAY` (note: **set** hides that
  object), `setmapscene VERMILION_PORT, SCENE_VERMILIONPORT_LEAVE_SHIP` and
  `warp VERMILION_PORT, 7, 17`. The Olivine-bound mirror is `._Olivine` ->
  `warp OLIVINE_PORT, 7, 23`.

**Flags and events**

| constant | defined in | read/written by | meaning for a bot |
|---|---|---|---|
| `EVENT_FAST_SHIP_FIRST_TIME` | `constants/event_flags.asm:57` | set by `VermilionPortLeaveShipScript`; read by both port scripts, `FastShip1FEnterShipScript`, `FastShip1FSailor2Script`, `SSAquaCaptain`, `FastShipBed`, `FastShipB1FSailorScript` | "the maiden crossing is finished"; gates the weekday schedule and the grandpa quest |
| `EVENT_FAST_SHIP_HAS_ARRIVED` | `constants/event_flags.asm:58` | cleared on boarding, set by `SSAquaMetalCoatAndDocking` / `FastShipBed.CanArrive`; read by `FastShip1FSailor1Script` | the door guard will only let you off once this is set |
| `EVENT_FAST_SHIP_DESTINATION_OLIVINE` | `constants/event_flags.asm:56` | cleared at Olivine, set at Vermilion | which port the ship is heading for |
| `EVENT_FAST_SHIP_1F_GENTLEMAN` | `constants/event_flags.asm:1230` | set at new game (`std_scripts.asm:497`), `appear`/`disappear` in `WorriedGrandpaSceneLeft` | grandpa sprite visibility |

On the maiden voyage only `EVENT_FAST_SHIP_PASSENGERS_FIRST_TRIP` is clear, so
Hiker Noland is the only trainer visible on this map - exactly what the
walkthrough describes.

  - `checkevent EVENT_FAST_SHIP_LAZY_SAILOR` / `iftrue .LazySailor` -> thanks you;
    if `EVENT_FAST_SHIP_FOUND_GIRL` is still clear he also prints

    `clearevent EVENT_FAST_SHIP_CABINS_NNW_NNE_NE_SAILOR` - **this is what spawns
    the lazy sailor** in the NNW/NNE/NE cabins map.
- The physical block is the sailor object standing on `(30,6)` or `(31,6)`; the
  coord events at `(30,7)`/`(31,7)` shuffle whichever sailor is active onto the
  tile you approached. Once `FastShipLazySailorScript` runs
  `setmapscene FAST_SHIP_B1F, SCENE_FASTSHIPB1F_NOOP`, the coord events stop
  firing and only one of the two tiles stays occupied.

  block `$4c`, animation `0` (`data/collision/field_move_blocks.asm:31`). It is
  the only cut tree on the map. The hidden Full Heal bg_event at `(12,19)` is the

## 4. Bot checklist

1. `NEW_BARK_TOWN` -> walk to `(6,3)`, warp 1, enter `ELMS_LAB`.
   Pre: `EVENT_BEAT_ELITE_FOUR` set. (An `SPECIALCALL_SSTICKET` phone call may
   fire on the way; answering it is optional.)
2. `ELMS_LAB` -> walk to `(5,3)` and face up to talk to `ELMSLAB_ELM` at `(5,2)`.
   Intent: talk. Pre: `EVENT_BEAT_ELITE_FOUR`, `!EVENT_GOT_SS_TICKET_FROM_ELM`.
   Post: `EVENT_GOT_SS_TICKET_FROM_ELM`, bag holds `S_S_TICKET`.
3. Fly to `OLIVINE_CITY`; walk to warp 10 `(19,27)` -> `OLIVINE_PORT_PASSAGE`.
4. `OLIVINE_PORT_PASSAGE`: warp 3 `(15,4)` -> lands at warp 4 `(3,2)`; then walk
   to warp 5 `(3,14)` -> `OLIVINE_PORT` warp 1 at `(11,7)`.
5. `OLIVINE_PORT`: walk onto `(7,15)`. Intent: walk (coord event).
   Post: yes/no prompt -> answer **Yes**; `checkitem S_S_TICKET` passes; the
   script auto-walks you 7 south and warps you to `FAST_SHIP_1F (25,1)`.
   Post-flags: `EVENT_TEMPORARY_UNTIL_MAP_RELOAD_2`,
   `!EVENT_FAST_SHIP_DESTINATION_OLIVINE`, scene `FAST_SHIP_1F` = 1.
   (Alternative: talk to `OLIVINEPORT_SAILOR3` at `(6,15)` for the same flow.)
6. `FAST_SHIP_1F`: the boarding cutscene runs on entry (scene 1). Then walk south
   to `(24,6)` or `(25,6)`. Intent: walk (coord event `WorriedGrandpaSceneLeft`).
   Post: scene -> `SCENE_FASTSHIP1F_NOOP`; nothing else changes.
7. `FAST_SHIP_1F` warp 3 at `(23,8)` -> `FAST_SHIP_CABINS_NNW_NNE_NE (2,12)`.
   Battle `TrainerHikerNoland` at `(4,17)` (sight 3, faces up).
   Post: `EVENT_BEAT_HIKER_NOLAND`.
8. Back to 1F; warp 5 at `(15,8)` -> `FAST_SHIP_CABINS_SW_SSW_NW (2,0)`; face the
   bed bg_event at `(7,1)`/`(7,2)` to heal (`FastShipBed` -> `special HealParty`).
   Do **not** expect the ship to dock yet.
9. 1F warp 6 at `(15,15)` -> `..._SW_SSW_NW (2,19)`. Battle
   `TrainerFirebreatherLyle` at `(1,15)`. Post: `EVENT_BEAT_FIREBREATHER_LYLE`.
10. 1F warp 8 at `(23,15)` -> `..._SE_SSE (2,7)`. Battle `TrainerPokefanmColin`
    at `(5,6)` and the twins at `(2,4)`/`(3,4)`.
    Post: `EVENT_BEAT_POKEFANM_COLIN`, `EVENT_BEAT_TWINS_MEG_AND_PEG`.
11. 1F warp 9 at `(27,15)` -> `..._SE_SSE (2,19)`. Talk to `SSAquaGrandpa` at
    `(2,17)`. Post: `setmapscene FAST_SHIP_1F, SCENE_FASTSHIP1F_NOOP` (flavour
    only; the errand is not flagged here).
12. 1F warp 12 at `(30,14)` -> `FAST_SHIP_B1F (31,13)`. Walk north onto `(31,7)`
    (or `(30,7)`). Intent: walk (coord event) -> a sailor moves in front of you.
    Talk to him. Post: `EVENT_FAST_SHIP_INFORMED_ABOUT_LAZY_SAILOR` set,
    `EVENT_FAST_SHIP_CABINS_NNW_NNE_NE_SAILOR` cleared.
13. Back to 1F; warp 4 at `(19,8)` -> `..._NNW_NNE_NE (2,24)`. Talk to the sailor
    at `(4,26)`. Intent: talk -> forced battle `SAILOR STANLY`.
    Post: `EVENT_BEAT_SAILOR_STANLY`, `EVENT_FAST_SHIP_LAZY_SAILOR`,
    `FAST_SHIP_B1F` scene -> `SCENE_FASTSHIPB1F_NOOP`, party healed.
14. `FAST_SHIP_B1F` again (1F warp 12 -> `(31,13)`): the corridor is now passable.
    Battle `TrainerJugglerFritz` at `(26,9)`, `TrainerSailorJeff` at `(9,11)`,
    `TrainerPicnickerDebra` at `(6,4)`.
15. `FAST_SHIP_B1F` warp 1 at `(5,11)` -> `FAST_SHIP_1F (6,12)`; then 1F warp 10
    at `(3,13)` -> `..._SE_SSE (2,33)`, the captain's cabin.
16. Talk to the granddaughter (`..._TWIN2`) at `(2,25)`. Intent: talk.
    Pre: `!EVENT_FAST_SHIP_CABINS_SE_SSE_CAPTAINS_CABIN_TWIN_2`.

    You end up standing in the grandpa's sub-room; leave via warp 3/4 `(2,19)`/`(3,19)`.
17. `FAST_SHIP_1F`: walk to `(25,3)` and talk to `FASTSHIP1F_SAILOR1` at `(25,2)`.
    Pre: `EVENT_FAST_SHIP_HAS_ARRIVED`.
    Post: `warp VERMILION_PORT, 7, 17`, `VERMILION_PORT` scene ->
    `SCENE_VERMILIONPORT_LEAVE_SHIP`.
18. `VERMILION_PORT`: the arrival scene runs (one step up). Post-flags include
    `EVENT_FAST_SHIP_FIRST_TIME`, `EVENT_FAST_SHIP_PASSENGERS_FIRST_TRIP`,
    `blackoutmod VERMILION_CITY`, `ENGINE_FLYPOINT_VERMILION` (map callback).
    Optional: face `(16,13)` for the hidden `IRON`.
19. Walk to warp 1 `(9,5)` -> `VERMILION_PORT_PASSAGE (3,14)`; warp 4 `(3,2)` ->
    warp 3 `(15,4)`; walk to warps 1/2 `(15,0)`/`(16,0)` -> `VERMILION_CITY`
    `(19,31)`/`(20,31)`.
20. `VERMILION_CITY` -> warp 3 at `(7,13)` -> `POKEMON_FAN_CLUB (2,7)`. Talk to
    the chairman at `(3,1)`; answer **Yes**.
    Post: `EVENT_LISTENED_TO_FAN_CLUB_PRESIDENT`, bag holds `RARE_CANDY`.
21. Optional: `VERMILION_POKECENTER_1F` via warp 2 `(9,5)` to heal.
22. Optional: face cell `(13,18)` and use CUT (needs `ENGINE_HIVEBADGE`), then
    face `(12,19)` for the hidden `FULL_HEAL`.
23. `VERMILION_CITY` warp 7 at `(10,19)` -> `VERMILION_GYM (4,17)`.
24. Gym: `TrainerGuitaristVincent` at `(4,7)` (sight 3, faces down),
    `TrainerJugglerHorton` at `(0,10)` (sight 4, faces right),
    `TrainerGentlemanGregory` at `(8,8)` (sight 4, faces left).
    All three are optional - Surge's win script sets their flags.
25. Walk to `(5,3)` and talk to `VERMILIONGYM_SURGE` at `(5,2)`.
    Pre: `!ENGINE_THUNDERBADGE`. Intent: talk -> battle `LT_SURGE, LT_SURGE1`.
    Post: `EVENT_BEAT_LTSURGE`, `EVENT_BEAT_GENTLEMAN_GREGORY`,
    `EVENT_BEAT_GUITARIST_VINCENT`, `EVENT_BEAT_JUGGLER_HORTON`,
    `ENGINE_THUNDERBADGE`. **Section complete.**

## 5. Port coverage

Everything in this section is data-driven: the Gen 2 side of this repo extracts
map headers, blocks, warps, coord/bg/object events and scene scripts generically
(`src/import/RomExtractorGen2.lua:804-977`) and runs the scripts through
`src/script/gen2/Vm.lua`. There is no per-map hand-port for any of these maps, so
"implemented" below means the generic mechanism exists and the ROM data drives
it, not that the beat has been played through.

| Beat | Port file | Status |
|---|---|---|
| Map load: blocks, collision quads, warps by cell | `src/world/gen2/Map.lua` | implemented (generic) |
| Warp / coord / bg event dispatch | `src/world/gen2/World.lua:5013` (coord), `:5148` (bg), `:1183` + `:5026` (scene scripts) | implemented (generic) |
| `verbosegiveitem` (S.S. TICKET, METAL COAT, RARE CANDY) | `src/script/gen2/Vm.lua:490-522` | implemented |
| `checkitem S_S_TICKET` boarding gate | `src/script/gen2/Vm.lua:523` | implemented |
| `loadtrainer` / `startbattle` (Stanly, Lt. Surge) | `src/script/gen2/Vm.lua:806`, `:918` (`winlosstext`) | implemented |
| `OBJECTTYPE_TRAINER` sight lines (ship + gym trainers) | `src/world/gen2/Trainers.lua:98` `Trainers.sees` | implemented |
| `TRAINERTYPE_MOVES` parties (Lt. Surge) and `TRAINERTYPE_ITEM` (Colin) | `src/import/RomExtractorGen2.lua:3900-3968` | implemented |
| `setmapscene` / `sdefer` scene plumbing (ports, ship, B1F) | `src/script/gen2/Vm.lua:92`, `:279` | implemented |
| `moveobject` + `appear` sailor-shuffle on B1F | `src/script/gen2/Vm.lua:337-350` (the comment calls out exactly this pattern) | implemented |
| `showemote` (grandpa's `!`) and `earthquake` (boarding) | `src/script/gen2/Vm.lua:961`, `:1799` | implemented |
| `blackoutmod` (cabin / Vermilion respawn) | `src/script/gen2/Vm.lua:1136` | implemented |
| `special HealParty` (bed, post-Stanly), `FadeOutToWhite/Black`, `ReloadSpritesNoPalettes`, `RestartMapMusic` | `src/script/gen2/Specials.lua:450`, `:998`, `:1025`, `:1059` | implemented |
| `specialphonecall SPECIALCALL_SSTICKET` | `src/script/gen2/Vm.lua:1364`; roster entry `src/core/gen2/Phone.lua:395` (`[5] = SPECIALCALL_SSTICKET`, condition `anywhere`) | implemented |
| CUT on the Vermilion tree (`TILESET_KANTO` `$35` -> `$4c`, anim 0) | `src/world/gen2/FieldMoves.lua:191-208`, `:242` | implemented |
| Hidden items (`PROTEIN`, `IRON`, `FULL_HEAL`) | `src/world/gen2/HiddenItems.lua:64`, `:112` | implemented |
| `ENGINE_FLYPOINT_VERMILION` from the map callback | `src/world/gen2/FieldMoves.lua:361` (`LANDMARK_VERMILION_CITY` -> `SPAWN_VERMILION`, flag 57) | implemented |
| `readvar VAR_BADGES` (Vermilion badge guy) | `src/world/gen2/World.lua:117`, `:1240` | implemented |
| `special SnorlaxAwake` | `src/script/gen2/Specials.lua:1562` | implemented |
| Water encounters / `FISHGROUP_OCEAN` at the ports | `src/battle/gen2/Encounter.lua` | not verified in this pass - no port-specific check was run |
| A driver that exercises the crossing end to end | `tests/drivers/gold_*.lua` | **missing** - no `gold_fastship_*`, `gold_vermilion_*` or `gold_surge_*` driver exists |
| Any hand-ported script for these 14 maps | - | **missing by design**; all behaviour comes from the extracted ROM script bytes |

Note: the many `Vermilion*` hits under `src/world/OverworldController.lua` and
`src/world/FieldDefaults.lua` are the **Gen 1** (pokered) Vermilion Gym trash-can
puzzle. That puzzle does not exist in Gold, and none of that code is on the Gen 2
path.

## 6. Unresolved / verify by hand

- **"cut down the tree blocking the gym" is wrong.** `maps/VermilionCity.blk` has
  exactly one cuttable block, `$35` at block `(6,9)`, whose `CUT_TREE` quadrant is
  cell `(13,18)`. The gym door is the `DOOR` quadrant of block `$12` at
  `(5,9)` = cell `(10,19)`, and the tiles south of it (`(10,20)`, `(11,20)`,
  `(12,20)`) are all `FLOOR`. Walking a straight path from the port entrance to
  the gym door never touches the tree. Cutting it only opens cell `(13,18)`, which
  is beside the hidden `FULL_HEAL` at `(12,19)`. Verified against
  `data/tilesets/kanto_collision.asm` rows `$12`, `$35`, `$4c`, `$31`.
- **"Meal Coat"** in the walkthrough's item list is a typo for `METAL_COAT`
  (`SSAquaMetalCoatAndDocking`). No `MEAL_*` item exists.
- **Lt. Surge's party order** in the walkthrough (Raichu, Magneton, Electabuzz,
  Electrode, Electrode) does not match `data/trainers/parties.asm:289-296`
  (Raichu, Electrode, Magneton, Electrode, Electabuzz).
- **Juggler Fritz's party order**: asm is Mr. Mime / Magmar / Machoke; the
  walkthrough says Mr. Mime / Machoke / Magmar.
- **"Lt. Surge has a Full Restore"** - the party entry is `TRAINERTYPE_MOVES`,
  which carries **no** held item. Gym-leader item use is AI behaviour
  (`data/trainers/attributes.asm` / the trainer-class AI item list), which was not
  opened in this pass. Verify before relying on it.
- **Prize money figures** ("You get: 1056G", "4600G", "???G" for Colin) are not
  stored anywhere in the asm as literals - Gen 2 computes them from base money x
  level. Not reproduced here.
- **EXP values** quoted per Pokemon are party- and level-dependent runtime
  calculations, not table data. Not reproduced here.
- **`EVENT_LISTENED_TO_FAN_CLUB_PRESIDENT_BUT_BAG_WAS_FULL`** is read by
  `PokemonFanClubChairmanScript` but is never `setevent`'d anywhere in
  `maps/PokemonFanClub.asm`. Either it is set elsewhere (nothing found by grep) or
  it is dead in this revision; a full-bag player appears to have to sit through
  the Rapidash speech again.
- **"Note the new Pokemon music for Kanto"**: the Vermilion maps use
  `MUSIC_VERMILION_CITY` (`data/maps/maps.asm:296`). Whether that is the "Kanto
  remix" the walkthrough means was not checked against the audio engine.
- The walkthrough's cabin-by-cabin narration ("two cabins to the right", "the
  cabin next to yours") was reconciled against the 1F warp `x` positions
  (north row `x` = 27/23/19/15, south row `x` = 15/19/23/27) and is consistent,
  but the prose ordering of trainers within `FAST_SHIP_B1F` ("head left, then
  down") was not re-walked tile by tile.
