# Section 16 - Routes 45, 46, 26 and 27
Source: `../section-16-routes-45-46-26-and-27.txt`
Maps covered: `MAP_ROUTE_45`, `MAP_ROUTE_46`, `MAP_ROUTE_27`, `MAP_TOHJO_FALLS`,
`MAP_ROUTE_27_SANDSTORM_HOUSE`, `MAP_ROUTE_26`, `MAP_ROUTE_26_HEAL_HOUSE`,
`MAP_DAY_OF_WEEK_SIBLINGS_HOUSE`, `MAP_VICTORY_ROAD_GATE` (gate only)
Badges / key milestones in this section: no badge. The milestones are the
MASTER BALL and EVERSTONE from Prof. Elm, TM37 SANDSTORM, TM22 SOLARBEAM, the
Tohjo Falls MOON STONE, and the eight-badge check at the Victory Road gate that
opens the Pokemon League.
Coordinate convention reminder: `warp_event` / `bg_event` / `object_event` rows
are in map **cells** (16 px walk grid). `map_const NAME, W, H` in
`constants/map_constants.asm` is in **blocks** (32 px), so a map is `W*2` by
`H*2` cells. Route 45 is `10, 45` blocks = 20 x 90 cells, which is why object
rows there run to y = 82.
---
## 1. Route order
| # | Map constant | asm file | Enter via | Leaves via | Why (walkthrough beat) |
|---|---|---|---|---|---|
| 1 | `MAP_ROUTE_45` | `maps/Route45.asm` | south connection from `BLACKTHORN_CITY` (`data/maps/attributes.asm`: `connection north, BlackthornCity, BLACKTHORN_CITY, 0`) | west connection to `ROUTE_46` (offset 36); optional warp 1 to `DARK_CAVE_BLACKTHORN_ENTRANCE` | Descend the mountain road, three forks, six trainers, four item balls |
| 2 | `MAP_ROUTE_46` | `maps/Route46.asm` | east connection from `ROUTE_45` (offset -36) | south connection to `ROUTE_29` (offset -10) or warps 1/2 to `ROUTE_29_ROUTE_46_GATE`; warp 3 to `DARK_CAVE_VIOLET_ENTRANCE` | Camper Ted, Picnicker Erin, Hiker Bailey, Dire Hit, two fruit trees |
| 3 | `MAP_NEW_BARK_TOWN` | `maps/NewBarkTown.asm` | FLY | warp 1 to `ELMS_LAB`, warp 2 to `PLAYERS_HOUSE_1F`; east connection to `ROUTE_27` | Elm hands the MASTER BALL (needs RISINGBADGE) and the EVERSTONE (needs Togepi shown). Map tables for New Bark Town belong to section 00; only the two Elm scripts are transcribed below. |
| 4 | `MAP_ROUTE_27` | `maps/Route27.asm` | west connection from `NEW_BARK_TOWN` (offset 0) - the crossing itself is water, so SURF | warp 2 / warp 3 into `TOHJO_FALLS`; warp 1 into `ROUTE_27_SANDSTORM_HOUSE`; east connection to `ROUTE_26` (offset -45) | "First step into KANTO" coord event, Rare Candy, then the eastern trainer gauntlet |
| 5 | `MAP_TOHJO_FALLS` | `maps/TohjoFalls.asm` | `Route27` warp 2 (26, 5) -> Tohjo warp 1 | Tohjo warp 2 (25, 15) -> `Route27` warp 3 | Cross the falls; MOON STONE item ball the walkthrough does not mention |
| 6 | `MAP_ROUTE_27` | `maps/Route27.asm` | Tohjo warp 2 | east connection to `ROUTE_26` | Megan ambush on exit, Sandstorm house, Blake/Brian/Gilbert, whirlpool island (Jose + TM22), Reena |
| 7 | `MAP_ROUTE_27_SANDSTORM_HOUSE` | `maps/Route27SandstormHouse.asm` | `Route27` warp 1 (33, 7) | warps 1/2 back to `Route27` warp 1 | Happiness check -> TM37 SANDSTORM |
| 8 | `MAP_ROUTE_26` | `maps/Route26.asm` | west connection from `ROUTE_27` (offset 45) | warp 1 (7, 5) to `VICTORY_ROAD_GATE` warp 3 | Scott, Richard, heal house, Joyce, Ice Berry, Gaven, Jake, Max Elixer, Beth |
| 9 | `MAP_ROUTE_26_HEAL_HOUSE` | `maps/Route26HealHouse.asm` | `Route26` warp 2 (15, 57) | warps 1/2 back to `Route26` warp 2 | Free full heal, repeatable |
| 10 | `MAP_DAY_OF_WEEK_SIBLINGS_HOUSE` | `maps/DayOfWeekSiblingsHouse.asm` | `Route26` warp 3 (5, 71) | warps 1/2 back to `Route26` warp 3 | Monica's journal (the day-of-week sibling roster) |
| 11 | `MAP_VICTORY_ROAD_GATE` | `maps/VictoryRoadGate.asm` | `Route26` warp 1 | warps 5/6 to `VICTORY_ROAD` | Eight-badge check. Victory Road itself belongs to section 17; only the gate's badge check is transcribed here because it is this section's terminal gate. |
Spill-over note: `DARK_CAVE_BLACKTHORN_ENTRANCE` / `DARK_CAVE_VIOLET_ENTRANCE`
are the "left path" the walkthrough points at from Routes 45 and 46; they are
section 15's maps. Their return warps are `DarkCaveBlackthornEntrance.asm`
`warp_event 23, 3, ROUTE_45, 1` and `DarkCaveVioletEntrance.asm`
`warp_event 35, 33, ROUTE_46, 3`.

## 2. Maps
### MAP_ROUTE_45
- Script: `maps/Route45.asm`
- Blocks: `maps/Route45.blk`
- Header: `data/maps/maps.asm:185` -> `map Route45, TILESET_JOHTO, ROUTE, LANDMARK_ROUTE_45, MUSIC_ROUTE_36, FALSE, PALETTE_AUTO, FISHGROUP_DRATINI_2`
- Dimensions: `constants/map_constants.asm:170` -> `map_const ROUTE_45, 10, 45` (20 x 90 cells)
- Connections (`data/maps/attributes.asm:243`): `connection north, BlackthornCity, BLACKTHORN_CITY, 0`; `connection west, Route46, ROUTE_46, 36`
- Symbols: `4d:4e75 Route45_MapScripts`, `4d:54ad Route45_MapEvents`
**Warps** (`def_warp_events`)
| idx | x | y | destination map | dest warp |
|---|---|---|---|---|
| 1 | 2 | 5 | `DARK_CAVE_BLACKTHORN_ENTRANCE` | 1 |
**Coord events** (`def_coord_events`)
None. Route 45 has no trip-wires; every scripted beat is an A press.
**BG events** (`def_bg_events`)
| x | y | type | script/item |
|---|---|---|---|
| 10 | 4 | `BGEVENT_READ` | `Route45Sign` ("ROUTE 45 / MOUNTAIN RD. AHEAD") |
| 13 | 80 | `BGEVENT_ITEM` | `Route45HiddenPpUp` -> `hiddenitem PP_UP, EVENT_ROUTE_45_HIDDEN_PP_UP` |
**Object events** (`def_object_events`)

|---|---|---|---|---|---|---|---|
| `ROUTE45_POKEFAN_M1` | `SPRITE_POKEFAN_M` | 10 | 16 | `STANDING_RIGHT` | `TRAINER` (sight 1) | `TrainerHikerErik` | -1 |
| `ROUTE45_POKEFAN_M2` | `SPRITE_POKEFAN_M` | 15 | 64 | `STANDING_RIGHT` | `TRAINER` (sight 2) | `TrainerHikerMichael` | -1 |
| `ROUTE45_POKEFAN_M3` | `SPRITE_POKEFAN_M` | 5 | 28 | `STANDING_LEFT` | `TRAINER` (sight 3) | `TrainerHikerParry` | -1 |
| `ROUTE45_POKEFAN_M4` | `SPRITE_POKEFAN_M` | 9 | 64 | `STANDING_LEFT` | `TRAINER` (sight 1) | `TrainerHikerTimothy` | -1 |

| `ROUTE45_COOLTRAINER_F` | `SPRITE_COOLTRAINER_F` | 4 | 36 | `STANDING_RIGHT` | `TRAINER` (sight 3) | `TrainerCooltrainerfKelly` | -1 |
| `ROUTE45_FRUIT_TREE` | `SPRITE_FRUIT_TREE` | 16 | 82 | `STILL` | `SCRIPT` | `Route45FruitTree` (`fruittree FRUITTREE_ROUTE_45`) | -1 |
| `ROUTE45_POKE_BALL1` | `SPRITE_POKE_BALL` | 6 | 51 | `STILL` | `ITEMBALL` | `Route45XSpecial` (`itemball X_SPECIAL`) | `EVENT_ROUTE_45_X_SPECIAL` |
| `ROUTE45_POKE_BALL2` | `SPRITE_POKE_BALL` | 6 | 66 | `STILL` | `ITEMBALL` | `Route45Revive` (`itemball REVIVE`) | `EVENT_ROUTE_45_REVIVE` |
| `ROUTE45_POKE_BALL3` | `SPRITE_POKE_BALL` | 4 | 21 | `STILL` | `ITEMBALL` | `Route45Elixer` (`itemball ELIXER`) | `EVENT_ROUTE_45_ELIXER` |
| `ROUTE45_POKE_BALL4` | `SPRITE_POKE_BALL` | 8 | 33 | `STILL` | `ITEMBALL` | `Route45MaxPotion` (`itemball MAX_POTION`) | `EVENT_ROUTE_45_MAX_POTION` |
**Scripts of interest**
- `TrainerBlackbeltKenji` (`4d:4e77`). Header is
`trainer BLACKBELT_T, KENJI3, EVENT_BEAT_BLACKBELT_KENJI, BlackbeltKenjiSeenText, BlackbeltKenjiBeatenText, 0, .Script`.
Post-battle `.Script`: `endifjustbattled` / `opentext` /
`checkevent EVENT_KENJI_READY_FOR_REMATCH` (rematch branch) /
`checkcellnum PHONE_BLACKBELT_KENJI` (already registered -> jump to the
"number accepted" std) / `checkevent EVENT_KENJI_ASKED_FOR_PHONE_NUMBER`.
First pass sets `EVENT_KENJI_ASKED_FOR_PHONE_NUMBER` and calls
`askforphonenumber PHONE_BLACKBELT_KENJI`; the return value is compared
against `PHONE_CONTACTS_FULL` and `PHONE_CONTACT_REFUSED`. This is the
walkthrough's "talk to him again and he will give you his phone number" -
the number is offered on the **second** A press, not the first.
`.WantsBattle` picks the rematch party by
`checkevent EVENT_RESTORED_POWER_TO_KANTO` -> `KENJI2`, else
`checkevent EVENT_BEAT_ELITE_FOUR` -> `KENJI1`, else `KENJI3`; then
`loadtrainer` / `startbattle` / `reloadmapafterbattle` /
`clearevent EVENT_KENJI_READY_FOR_REMATCH`.
- `TrainerHikerParry` (`4d:4f2d`) is the same shape with
`PHONE_HIKER_PARRY`, `EVENT_PARRY_ASKED_FOR_PHONE_NUMBER`,
`EVENT_PARRY_READY_FOR_REMATCH`, and `PARRY3` as the first-meeting party
(`PARRY1` after the Elite Four, `PARRY2` after Kanto's power is restored).
Note `gettrainername STRING_BUFFER_3, HIKER, PARRY1` - the displayed name is
read off `PARRY1` even though the fight is `PARRY3`.
- `TrainerHikerErik`, `TrainerHikerMichael`, `TrainerHikerTimothy`,
`TrainerCooltrainermRyan`, `TrainerCooltrainerfKelly`: plain
`endifjustbattled` / `opentext` / `writetext ...AfterBattleText` /
`waitbutton` / `closetext` / `end`. No flags beyond the `trainer` header's
own beat flag.
- `Route45FruitTree` = `fruittree FRUITTREE_ROUTE_45`. Index 12 in
`constants/script_constants.asm:218`; `data/items/fruit_trees.asm` row 12 is
`MYSTERYBERRY` - the walkthrough's "Mystery Berry".
- `Route45HiddenPpUp` = `hiddenitem PP_UP, EVENT_ROUTE_45_HIDDEN_PP_UP`, at
cell (13, 80). Not mentioned by the walkthrough at all.

---
### MAP_NEW_BARK_TOWN (Elm's Lab beats only)
The New Bark Town / Elm's Lab map tables belong to section 00. What this
section needs is the two `ProfElmScript` branches the walkthrough triggers.
- `maps/ElmsLab.asm:50` `ProfElmScript`:
`faceplayer` / `opentext` / `checkevent EVENT_GOT_SS_TICKET_FROM_ELM`
(-> `ElmCheckMasterBall`) / `checkevent EVENT_BEAT_ELITE_FOUR`
(-> `ElmGiveTicketScript`).
- `ElmCheckMasterBall`: `checkevent EVENT_GOT_MASTER_BALL_FROM_ELM` /
`checkflag ENGINE_RISINGBADGE` -> `ElmGiveMasterBallScript`. **This is the
actual gate on the Master Ball: the eighth Johto badge, not "eight badges"
counted.** `constants/engine_flags.asm:45` is `ENGINE_RISINGBADGE`.
- `ElmGiveMasterBallScript` (`60:4268`): `verbosegiveitem MASTER_BALL` /
`iffalse .notdone` / `setevent EVENT_GOT_MASTER_BALL_FROM_ELM`. A full bag
means the flag is never set, so a bot must have a free slot.
- `ElmCheckEverstone`: `checkevent EVENT_GOT_EVERSTONE_FROM_ELM` /
`checkevent EVENT_SHOWED_TOGEPI_TO_ELM` -> `ElmGiveEverstoneScript` /
`checkevent EVENT_TOLD_ELM_ABOUT_TOGEPI_OVER_THE_PHONE`, then
`setval TOGEPI` + `special FindPartyMonThatSpeciesYourTrainerID`, and the
same for `TOGETIC`. That special is why the walkthrough tells you to
**withdraw Togepi into the party first** - the check is a party scan, and it
additionally requires the mon to be your own OT.
- `ShowElmTogepiScript` sets `EVENT_SHOWED_TOGEPI_TO_ELM` and falls into
`ElmGiveEverstoneScript` (`60:424f`): `verbosegiveitem EVERSTONE` /
`iffalse ElmScript_NoRoomForEverstone` / `setevent EVENT_GOT_EVERSTONE_FROM_ELM`.
- Mom's savings: `maps/PlayersHouse1F.asm:85` `MomScript`, `.BankOfMom` at
line 115 runs `special BankOfMom`.
---

`writetext Route27FisherHeyText`, `writetext Route27FisherText` ("You've taken
your first step into KANTO"), then `setscene SCENE_ROUTE27_NOOP` (1) so it never
fires again. The scene constants are generated by the `def_scene_scripts` /
`scene_script` macros in `macros/scripts/maps.asm`; the sym table confirms
`SCENE_ROUTE27_FIRST_STEP_INTO_KANTO = 00` and `SCENE_ROUTE27_NOOP = 01`.

### MAP_DAY_OF_WEEK_SIBLINGS_HOUSE
- Script: `maps/DayOfWeekSiblingsHouse.asm`

`DayOfWeekSiblingsHousePokedexScript` is two nested `yesorno` prompts over
`DayOfWeekSiblingsHousePokedexText1/2/3`. Text 3 is Monica's roster, and it
matches the walkthrough exactly: Monday MONICA / ROUTE 40, Tuesday TUSCANY /
ROUTE 29, Wednesday WESLEY / LAKE OF RAGE, Thursday ARTHUR / ROUTE 36, and so
on. Pure text - no flags, no items.

### MAP_VICTORY_ROAD_GATE (badge check only)
Victory Road itself is section 17. Transcribed here because the gate is this
section's terminal blocker.
- Script: `maps/VictoryRoadGate.asm`

`_VictoryRoadGateBadgeCheckScript`:
```

applymovement PLAYER, VictoryRoadGateStepDownMovement ; one step DOWN
end
.AllEightBadges:
writetext VictoryRoadGateEightBadgesText / waitbutton / closetext
setscene SCENE_VICTORYROADGATE_NOOP
end
```
`readvar VAR_BADGES` is a **popcount of the Johto badge byte**, not a badge
index. `setscene SCENE_VICTORYROADGATE_NOOP` (1) permanently disarms the coord
event once you pass. The two black belts are hidden until
`EVENT_OPENED_MT_SILVER` / `EVENT_FOUGHT_SNORLAX`
(`constants/event_flags.asm:1265`, `:1266`), so on a first pass neither is
present.

Nothing on Routes 45, 46 or 26 is gated by an `EVENT_*` or a badge. Route 27 is
the only map in this section where a field move blocks forward progress.

## 6. Unresolved / verify by hand
1. **"Camper Quentin" does not exist in pokegold.** The walkthrough puts a
Camper Quentin on Route 45 with 27 FEAROW / 30 PRIMEAPE / 30 TAUROS. There
is no `QUENTIN` constant anywhere in the checkout
(`grep -rn QUENTIN /Users/bryanbassett/Documents/development/pokegold` is
empty), no camper object on `maps/Route45.asm`, and the only TAUROS line in
`data/trainers/parties.asm` is a level 35 one in `CooltrainerMGroup` "SEAN".
The Route 45 trainer the walkthrough is probably confusing this with is
Hiker Michael (25 GEODUDE / 25 GRAVELER / 25 GOLEM), whom it never mentions.
2. **"A Revive and a Nugget" on Route 45.** There is no NUGGET on Route 45.
The four item balls are X_SPECIAL, REVIVE, ELIXER and MAX_POTION, and the
only hidden item is `hiddenitem PP_UP, EVENT_ROUTE_45_HIDDEN_PP_UP` at
(13, 80). Treat "Nugget" as an error and pick up the PP UP instead.
3. **Route 27 Rare Candy placement.** The walkthrough says to surf "southeast
of the cave entrance" *before* entering Tohjo Falls. The item ball is at
cell (53, 12), which is east of the *eastern* Tohjo exit (36, 5) and far
east of the western entrance (26, 5). Whether the southern water is
continuous from the landing point (~x 18-21) all the way to x 53 was not
verified - it would need reading `maps/Route27.blk` against the
`TILESET_JOHTO` collision table. A bot should simply grab it on the way to
Blake rather than trusting the stated ordering.
4. **Cooltrainer Gaven's second mon.** The walkthrough says Krabby; the asm
says `db 32, KINGLER` in `CooltrainerMGroup` entry 10.
5. **Cooltrainer Reena's party order.** Walkthrough: STARMIE, STARMIE,
NIDOQUEEN. Asm (`CooltrainerFGroup` entry 10): 31 STARMIE, 33 NIDOQUEEN,
31 STARMIE.
6. **Hiker Erik's party order.** Walkthrough: Machop, Machop, Graveler. Asm
(`HikerGroup` entry 7): 24 MACHOP, 27 GRAVELER, 27 MACHOP.
7. **Wild lists are incomplete in the walkthrough.** Route 46 also has
JIGGLYPUFF (3 and 5); Tohjo Falls also has ZUBAT, GOLBAT, RATICATE and
GOLDEEN; Route 26/27's ARBOK entries are Silver-only while SANDSLASH and
DODRIO are the Gold slots. The walkthrough's per-route lists appear to be a
Gold/Silver merge.
8. **Tohjo Falls MOON STONE is never mentioned.** `TohjoFallsMoonStone` at
(2, 6) is the only object on the map.
9. **"Head down the other waterfall".** There is no downward WATERFALL move in
the engine. Descending is a `COLL_CURRENT_DOWN` ($3b) tile that carries the
surfing player; `CheckWaterfallTile` (`home/map_objects.asm:185`) accepts
both `COLL_WATERFALL` and `COLL_CURRENT_DOWN` precisely so the climb loop
keeps running. Whether the port's `World:waterfallStep` handles the descend
direction as well as the climb was not verified.
10. **Kenji's phone number timing.** The walkthrough says "talk to him again
and he will give you his phone number", which matches - but the asm needs
*two* post-battle talks: the first sets
`EVENT_KENJI_ASKED_FOR_PHONE_NUMBER` and runs `AskNumber1MScript`, and
`askforphonenumber` only runs after that `scall` returns. Bots should
budget two A-press cycles per phone trainer, not one.
11. The walkthrough's Route 45 "LEFT PATH ... Elixir ... one trainer (Hiker
Parry)" reads as if the Elixir is inside Dark Cave. Both the Elixir
(4, 21) and Parry (5, 28) are on Route 45 itself. There *is* a separate
hidden Elixer inside Dark Cave (`maps/DarkCaveVioletEntrance.asm`
`bg_event 26, 3, BGEVENT_ITEM, DarkCaveVioletEntranceHiddenElixer`), which
belongs to section 15.
