# Section 08 - Olivine Lighthouse and Cianwood City Gym
Source: `../section-08-olivine-lighthouse-and-cianwood-city-gym.txt`
Maps covered: `MAP_ROUTE_38_ECRUTEAK_GATE`, `MAP_ROUTE_38`, `MAP_ROUTE_39`,
`MAP_ROUTE_39_BARN`, `MAP_ROUTE_39_FARMHOUSE`, `MAP_OLIVINE_CITY`,
`MAP_OLIVINE_POKECENTER_1F`, `MAP_OLIVINE_GOOD_ROD_HOUSE`, `MAP_OLIVINE_CAFE`,
`MAP_OLIVINE_MART`, `MAP_OLIVINE_LIGHTHOUSE_1F` .. `MAP_OLIVINE_LIGHTHOUSE_6F`,
`MAP_ROUTE_40`, `MAP_ROUTE_41`, `MAP_CIANWOOD_CITY`, `MAP_MANIAS_HOUSE`,
`MAP_CIANWOOD_PHARMACY`, `MAP_CIANWOOD_PHOTO_STUDIO`,
`MAP_CIANWOOD_POKECENTER_1F`, `MAP_CIANWOOD_LUGIA_SPEECH_HOUSE`,
`MAP_CIANWOOD_GYM`
Badges / key milestones in this section: **Storm Badge** (`ENGINE_STORMBADGE`,
badge 5, from `CianwoodGymChuckScript`). Other milestones, in the order the
walkthrough hits them: `EVENT_GOT_GOOD_ROD`, `EVENT_GOT_HM04_STRENGTH`
(HM04 = the Cianwood Gym boulder puzzle and every later Strength rock),
`EVENT_JASMINE_EXPLAINED_AMPHYS_SICKNESS` (the flag that unlocks the Cianwood
pharmacist), `EVENT_GOT_SHUCKIE`, `EVENT_GOT_SECRETPOTION_FROM_PHARMACY`,
`EVENT_BEAT_CHUCK`, `EVENT_GOT_TM01_DYNAMICPUNCH`, `EVENT_GOT_HM02_FLY`, and
the two fly-point engine flags `ENGINE_FLYPOINT_OLIVINE` /
`ENGINE_FLYPOINT_CIANWOOD`.
Coordinate note: every `warp_event` / `coord_event` / `bg_event` /
`object_event` x,y below is copied verbatim from the map asm. Those are 0-based
walk-grid cells (2 per map block, so a `W`-block-wide map runs x = 0..2W-1),
the same grid `src/world/gen2/Map.lua` calls a cell.

## 1. Route order
| # | Map constant | asm file | Enter via | Leaves via | Why (walkthrough beat) |
|---|---|---|---|---|---|
| 1 | `MAP_ROUTE_38_ECRUTEAK_GATE` | `maps/Route38EcruteakGate.asm` | warp 3/4 at (9,4)/(9,5) from `ECRUTEAK_CITY` warps 14/15 | warp 1/2 at (0,4)/(0,5) | "Well, go through the building into Route 38" |
| 2 | `MAP_ROUTE_38` | `maps/Route38.asm` | warp 1/2 at (35,8)/(35,9) | west connection to `ROUTE_39` (`data/maps/attributes.asm:215`) | "You're heading west. There are trainers" - Toby, Harry, Dana, Valerie, Chad, plus the Berry tree |

| 10 | `MAP_OLIVINE_LIGHTHOUSE_6F` | `maps/OlivineLighthouse6F.asm` | warp 1 at (9,15) | warps 2/3 at (16,5)/(17,5) - the right-wall drop chain | "Talk to the person on that level, and it is Gym Leader Jasmine" |
| 11 | `MAP_OLIVINE_CITY` | `maps/OlivineCity.asm` | lighthouse 1F warps 1/2 at (10,17)/(11,17) | west connection to `ROUTE_40` (`data/maps/attributes.asm:145`) | heal, restock at the Mart (warp 8 at (19,17)), teach HM03 Surf |
| 12 | `MAP_ROUTE_40` | `maps/Route40.asm` | east connection from `OLIVINE_CITY` | south connection to `ROUTE_41` (`data/maps/attributes.asm:223`) | "activate Surf by clicking A at the water" - Simon, Elaine, Paula, Randall |
| 13 | `MAP_ROUTE_41` | `maps/Route41.asm` | north connection from `ROUTE_40` | west connection to `CIANWOOD_CITY` (`data/maps/attributes.asm:227`) | the nine open-sea swimmers; the four Whirl Islands warps are optional detours |
| 14 | `MAP_CIANWOOD_CITY` | `maps/CianwoodCity.asm` | east connection from `ROUTE_41` (`data/maps/attributes.asm:136`) | warp 2 at (8,43) | "You will reach land after that battle. Welcome to Cianwood City." |
| 14a | `MAP_CIANWOOD_POKECENTER_1F` | `maps/CianwoodPokecenter1F.asm` | Cianwood warp 3 at (23,43) | warp 1/2 at (3,7)/(4,7) | "Heal at the Pokémon Center and clear a space so you can acquire another Pokémon" |
| 14b | `MAP_MANIAS_HOUSE` | `maps/ManiasHouse.asm` | Cianwood warp 1 at (17,41) | warp 1/2 at (2,7)/(3,7) | "a PokeManiac will give you Level 15 Shuckie the Shuckle" |
| 14c | `MAP_CIANWOOD_PHARMACY` | `maps/CianwoodPharmacy.asm` | Cianwood warp 4 at (15,47) | warp 1/2 at (2,7)/(3,7) | "It's the Pharmacy. A guy inside the house, wearing sunglasses will give you some medicine" |
| 14d | `MAP_CIANWOOD_PHOTO_STUDIO` | `maps/CianwoodPhotoStudio.asm` | Cianwood warp 5 at (9,31) | warp 1/2 at (2,7)/(3,7) | "he will offer to take pictures of your Pokémon" (optional) |
| 15 | `MAP_CIANWOOD_GYM` | `maps/CianwoodGym.asm` | Cianwood warp 2 at (8,43) | warp 1/2 at (4,17)/(5,17) | "face Chuck, the fighting gym leader" -> Storm Badge + TM01 |
| 16 | `MAP_CIANWOOD_CITY` | `maps/CianwoodCity.asm` | gym warp 1/2 | (section ends) | "Talk to the lady outside the gym and she will give you HM02 Fly" |
Spills into the next section: the walkthrough's last line, "You'll want to
return to Olivine now so that you can give the medicine to Jasmine and the
Ampharos", starts the Olivine Gym / `MAP_OLIVINE_GYM` beat. The Secretpotion
hand-off itself is `OlivineLighthouseJasmine` on `MAP_OLIVINE_LIGHTHOUSE_6F`
(documented below, because the flag it clears is what makes Jasmine appear in
the gym), but the gym fight belongs to section 09. Likewise the walkthrough's
"Items found in Olivine City: … TM23" is Jasmine's TM in `maps/OlivineGym.asm`,
not anything reachable on `MAP_OLIVINE_CITY`.

- Dimensions (`constants/map_constants.asm:50`): `map_const ROUTE_38, 20, 9` (40x18 cells)
- Connections (`data/maps/attributes.asm:215`): west `Route39` / `ROUTE_39` offset 0; east `EcruteakCity` / `ECRUTEAK_CITY` offset -5

**Scripts of interest**
- `Route38FruitTree`: single opcode `fruittree FRUITTREE_ROUTE_38`.
`data/items/fruit_trees.asm:6` maps that index to `BERRY`. This is the
walkthrough's "Go left and you'll get a Berry".
- `TrainerLassDana1.Script`: after the win it runs the standard phone-number
offer. `checkevent EVENT_DANA_READY_FOR_REMATCH` -> rematch arm;
`checkcellnum PHONE_LASS_DANA` -> already registered; otherwise it prints
`LassDanaMoomooMilkText`, sets `EVENT_DANA_ASKED_FOR_PHONE_NUMBER`, and calls
`askforphonenumber PHONE_LASS_DANA`. The rematch arm picks the party by
progress: `checkevent EVENT_CLEARED_RADIO_TOWER` -> `LASS, DANA3`, else
`checkflag ENGINE_FLYPOINT_CIANWOOD` -> `LASS, DANA2`, else `LASS, DANA1`.
Note that flag: the moment a bot walks into Cianwood in this section, Dana's
rematch upgrades to `DANA2`.
- `TrainerSchoolboyChad1.Script`: same shape, `PHONE_SCHOOLBOY_CHAD`, rematch
tier keyed on `EVENT_CLEARED_RADIO_TOWER` -> `CHAD3`, else
`checkflag ENGINE_FLYPOINT_MAHOGANY` -> `CHAD2`, else `CHAD1`.
- Toby, Valerie and Harry are plain `endifjustbattled / opentext / writetext /
waitbutton / closetext / end` after-battle scripts. No flags beyond their own
`EVENT_BEAT_*`.
**Flags and events**
| constant | defined in | read/written by | meaning for a bot |

**Wild encounters**
`data/wild/johto_grass.asm:2014`, `def_grass_wildmons ROUTE_38`, rates
`10 percent, 10 percent, 10 percent` (morn/day/nite). Gold build
(`IF DEF(_GOLD)`):
- morn and day, in slot order: 16 RATTATA, 16 RATICATE, 16 MAGNEMITE,
16 FARFETCH_D, 13 MILTANK, 13 TAUROS, 13 SNUBBULL
- nite: identical except slot 4 is 16 RATTATA instead of FARFETCH_D
Silver swaps RATTATA for MEOWTH in slots 1 and (at night) 4. Headbutt:

`PHONE_POKEFANM_DEREK`; rematch tier is `EVENT_BEAT_ELITE_FOUR` -> `DEREK3`,
else `checkflag ENGINE_FLYPOINT_LAKE_OF_RAGE` -> `DEREK2`, else `DEREK1`.
- Ruth, Eugene and Norman are plain after-battle scripts.
**Flags and events** - trainer `EVENT_BEAT_*` bits plus
`EVENT_ROUTE_39_HIDDEN_NUGGET` (`constants/event_flags.asm:180`),
`EVENT_DEREK_ASKED_FOR_PHONE_NUMBER` / `EVENT_DEREK_READY_FOR_REMATCH`.
**Items**
| item | how obtained | source | one-time flag |
|---|---|---|---|
| `MINT_BERRY` | fruit tree at (9,3) | `Route39FruitTree` | none (daily) |
| `NUGGET` | hidden, stand on/face (5,13) and press A | `Route39HiddenNugget` bg_event | `EVENT_ROUTE_39_HIDDEN_NUGGET` |
The walkthrough does not mention the Nugget.

**Wild encounters**
`data/wild/johto_grass.asm:2069`, `def_grass_wildmons ROUTE_39`. Gold rates are
`2 percent, 2 percent, 10 percent` (Silver: 2/2/2 - Gold gets a much higher
night rate here).
- morn and day: 16 RATTATA, 17 RATICATE, 16 MAGNEMITE, 16 FARFETCH_D,
15 MILTANK, 15 TAUROS, 15 TAUROS

`ifequal 3` / `ifequal 5` / `ifequal 7` for the three progress texts.
At **7** berries it plays `MUSIC_HEAL` and
`setevent EVENT_HEALED_MOOMOO`.

The rival object sits on the gym door tile and is **masked** while
`EVENT_RIVAL_OLIVINE_CITY` is set (`CheckObjectFlag`,
`engine/overworld/map_objects_2.asm:32` - a set flag hides the object).
`InitializeEventsScript` sets it on a new game
(`engine/events/std_scripts.asm:520`), so the rival is invisible until the
scene's `appear` clears it.
**Scripts of interest**
- `OlivineCityFlypointCallback` (`callback MAPCALLBACK_NEWMAP`,
`pokegold.sym` 49:400f): a single `setflag ENGINE_FLYPOINT_OLIVINE`.
Walking into Olivine at all registers the fly point.
- `OlivineCityRivalSceneTop` (`pokegold.sym` 49:4013) and
`OlivineCityRivalSceneBottom` (49:404b). Both:

`special RestartMapMusic` /
`variablesprite SPRITE_OLIVINE_RIVAL, SPRITE_SWIMMER_GUY` /
`special LoadUsedSpritesGFX`.
**There is no battle.** The walkthrough is right: he only talks.
The `variablesprite` at the end is load-bearing - it re-points the
`SPRITE_OLIVINE_RIVAL` slot at `SPRITE_SWIMMER_GUY`, which is why the Route 40
and Route 41 swimmers use `SPRITE_OLIVINE_RIVAL` in their `object_event` rows.
Movements: top variant approach `DOWN, RIGHT, RIGHT`, player steps
`DOWN` + `turn_head UP`, rival leaves `RIGHT x6, UP x6`. Bottom variant
approach `DOWN, DOWN, RIGHT, RIGHT`, player steps `UP` + `turn_head DOWN`,
rival leaves `RIGHT x6, UP x5`.

Floor-to-floor structure, from the six `def_warp_events` blocks. There are two
vertical routes: the interior stairs (varying coordinates) and a right-wall
column at x = 16/17 that the walkthrough calls "the holes on the right side of
every floor". Each right-wall pair is mirrored at identical coordinates on the
floor it links to.

| 6F w2/w3 | 16,5 / 17,5 | 5F | 6 / 7 | start of the descent chain out |
Descent chain the walkthrough describes, in order:
6F (16,5) -> 5F (16,5); walk to 5F (16,7) -> 4F (16,7); walk to 4F (16,9) ->
3F (16,9); walk to 3F (16,11) -> 2F (16,11); walk to 2F (16,13) ->
1F (16,13); then 1F warp 1/2 at (10,17)/(11,17) back to Olivine.

`EVENT_OLIVINE_LIGHTHOUSE_JASMINE` is **not** set by
`InitializeEventsScript`, so Jasmine is visible from the start; the script's
own `disappear` sets it once she leaves.
**Scripts of interest**
- `OlivineLighthouseJasmine` (`pokegold.sym` 44:6ccd). Three arms:
1. `checkitem SECRETPOTION` -> `.BroughtSecretpotion` (the cure scene).
2. Otherwise `checkevent EVENT_JASMINE_EXPLAINED_AMPHYS_SICKNESS` ->
`.ExplainedSickness` (short reminder text).
3. First visit: `writetext JasmineCianwoodPharmacyText`, `promptbutton`,
**`setevent EVENT_JASMINE_EXPLAINED_AMPHYS_SICKNESS`**, then the reminder.
This flag is the whole point of the lighthouse climb: it is what
`CianwoodPharmacist` checks before it will hand over the Secretpotion.
4. `.BroughtSecretpotion`: `yesorno` (NO -> `.Refused`, nothing lost), then
`takeitem SECRETPOTION`, the healing cut-scene (`playmusic MUSIC_HEAL`,
`cry AMPHAROS`, `special FadeOutToWhite` / `FadeInFromWhite`), then
**`setevent EVENT_JASMINE_RETURNED_TO_GYM`** and
**`clearevent EVENT_OLIVINE_GYM_JASMINE`** (the latter un-masks her object
in `maps/OlivineGym.asm`; `InitializeEventsScript` sets it at
`engine/events/std_scripts.asm:511`). Finally it branches on
`readvar VAR_FACING` (DOWN / RIGHT / other) to pick one of three exit
movement scripts and `disappear OLIVINELIGHTHOUSE6F_JASMINE`.
- `OlivineLighthouseAmphy`: `checkevent EVENT_JASMINE_RETURNED_TO_GYM` picks
the weak cry (`special PlaySlowCry`) or the healthy one.
**Flags and events**
| constant | defined in | read/written by | meaning for a bot |
|---|---|---|---|
| `EVENT_JASMINE_EXPLAINED_AMPHYS_SICKNESS` | `constants/event_flags.asm:64` | set by `OlivineLighthouseJasmine`, read by `CianwoodPharmacist` | **hard gate** on the Secretpotion |
| `EVENT_JASMINE_RETURNED_TO_GYM` | `constants/event_flags.asm:41` | set after the cure | gates the Olivine Gym fight (section 09) |
| `EVENT_OLIVINE_GYM_JASMINE` | `constants/event_flags.asm:1141` | set by `InitializeEventsScript`, cleared here | while set, Jasmine's gym object is masked |
| `EVENT_OLIVINE_LIGHTHOUSE_JASMINE` | `constants/event_flags.asm:1140` | set by `disappear` at the end | removes her from 6F afterwards |
**Items**

- Dimensions (`constants/map_constants.asm:412`): `map_const MANIAS_HOUSE, 4, 4`
- Attributes (`data/maps/attributes.asm:651`): no connections
**Warps**: 1 (2,7) -> `CIANWOOD_CITY` 1; 2 (3,7) -> `CIANWOOD_CITY` 1.
**Coord events / BG events** - none.
**Object events**
| const | sprite | x | y | movement | type | script label | event flag |
|---|---|---|---|---|---|---|---|
| `MANIASHOUSE_ROCKER` | `SPRITE_ROCKER` | 2 | 4 | `SPRITEMOVEDATA_SPINRANDOM_SLOW` | `OBJECTTYPE_SCRIPT` | `ManiaScript` | -1 |
**Scripts of interest**
- `ManiaScript` (`pokegold.sym` 5d:4f6d):
1. `checkevent EVENT_MANIA_TOOK_SHUCKIE_OR_LET_YOU_KEEP_HIM` -> happiness
speech, done forever.
2. `checkevent EVENT_GOT_SHUCKIE` -> `.alreadyhaveshuckie`, which checks
`checkflag ENGINE_GOT_SHUCKIE_TODAY` (`constants/engine_flags.asm:102`);
if that daily flag is clear he asks for Shuckie back
(`.returnshuckie`).
3. First time: `writetext ManiaText_AskLookAfterShuckle`, `yesorno`,
**`special GiveShuckle`** (`iffalse .partyfull`), then
`setevent EVENT_GOT_SHUCKIE`.
4. `.returnshuckie`: `special ReturnShuckie` and a five-way `ifequal` on
`SHUCKIE_WRONG_MON` / `SHUCKIE_REFUSED` / `SHUCKIE_HAPPY` /
`SHUCKIE_FAINTED` (constants in `constants/script_constants.asm`).
`SHUCKIE_HAPPY` is the "it likes you enough, keep it" arm the
walkthrough's Thard_Verad note describes, and it also sets
`EVENT_MANIA_TOOK_SHUCKIE_OR_LET_YOU_KEEP_HIM`.
**Flags and events**
| constant | defined in | read/written by | meaning for a bot |
|---|---|---|---|
| `EVENT_GOT_SHUCKIE` | `constants/event_flags.asm:78` | `ManiaScript` | Shuckie is in your party |
| `EVENT_MANIA_TOOK_SHUCKIE_OR_LET_YOU_KEEP_HIM` | `constants/event_flags.asm:79` | `.returnshuckie` arms | the encounter is finished |
| `ENGINE_GOT_SHUCKIE_TODAY` | `constants/engine_flags.asm:102` | daily flag, read by `.alreadyhaveshuckie` | he will not ask for it back on the day you got it |
**Items** - Shuckie is a party member, not a bag item. A bot must have a free
party slot: `GiveShuckle` returns false and the script prints
`ManiaText_PartyFull` otherwise. This is what "clear a space so you can acquire
another Pokémon" means.

`checkevent EVENT_GOT_SECRETPOTION_FROM_PHARMACY / iftrue .Mart`, then

Only with that flag set does it run `giveitem SECRETPOTION`,
`playsound SFX_KEY_ITEM`, `itemnotify`,
`setevent EVENT_GOT_SECRETPOTION_FROM_PHARMACY`. Otherwise it just opens the
shop: `pokemart MARTTYPE_PHARMACY, MART_CIANWOOD` -> `MartCianwood`
(`data/items/marts.asm:84`): POTION, SUPER_POTION, HYPER_POTION, FULL_HEAL,
REVIVE.
**Gate for a bot**: you must talk to Jasmine on Lighthouse 6F *before* the
pharmacist will give you anything. Skipping the lighthouse and sailing
straight to Cianwood silently gets you a shop menu and no Secretpotion.
**Items**
| item | how obtained | source | one-time flag |

The puzzle the walkthrough describes is `BOULDER2`/`BOULDER3`/`BOULDER4`, the
row at y = 7, x = 3/4/5. `BOULDER1` at (5,1) is Chuck's prop: he throws it as
part of his intro. Blackbelt Lung at (5,5) is behind the boulder row - the
walkthrough's "Use Strength to push your way to the last trainer before the gym
leader".
**Scripts of interest**

it only matters if you took Chuck out of order.

**Bot-critical**: collecting the TM marks all four Blackbelts as beaten.
Fight them *before* Chuck or their EXP and money are gone.
- `CianwoodGymBoulder`: `jumpstd StrengthBoulderScript` ->
`farsjump AskStrengthScript` (`engine/events/std_scripts.asm:196`,

| Secretpotion from the Cianwood pharmacist | `maps/CianwoodPharmacy.asm:CianwoodPharmacist` - `checkevent EVENT_JASMINE_EXPLAINED_AMPHYS_SICKNESS / iffalse .Mart` | that flag | talk to Jasmine on `MAP_OLIVINE_LIGHTHOUSE_6F` (`OlivineLighthouseJasmine`) |
| HM02 Fly from Chuck's wife | `maps/CianwoodCity.asm:CianwoodCityChucksWife` - `checkevent EVENT_BEAT_CHUCK` | Chuck beaten | `CianwoodGymChuckScript` |
| Using Fly in the field | `engine/events/overworld.asm:545` `FlyFunction.TryFly` - `ld de, ENGINE_STORMBADGE` | Storm Badge | the same gym win |
| Route 41 whirlpool tiles (Whirl Islands access only) | `engine/events/overworld.asm:1077` `WhirlpoolFunction.TryWhirlpool` / `:1171` `TryWhirlpoolOW` - `ld de, ENGINE_GLACIERBADGE` | Glacier Badge + `WHIRLPOOL` | Pryce, much later. **Not** required to reach Cianwood - the walkthrough's route only passes whirlpools, it never crosses one |
| Moomoo Farm berry feeding | `maps/Route39Barn.asm:MoomooScript` - `checkevent EVENT_TALKED_TO_FARMER_ABOUT_MOOMOO` | talk to `PokefanM_DairyFarmer` first | `PokefanM_DairyFarmer` sets it unconditionally |
| TM13 SNORE | `maps/Route39Farmhouse.asm:FarmerFScript_GiveSnore` - `checkevent EVENT_HEALED_MOOMOO` | 7 Berries fed to Moomoo | `MoomooScript.SevenBerries` |
| Shuckie | `maps/ManiasHouse.asm:ManiaScript` - `special GiveShuckle` returns false on a full party | one free party slot | box a mon at the Pokecenter first |
| Olivine rival cut-scene | `coord_event 13,12` / `13,13` gated on `SCENE_OLIVINECITY_RIVAL_ENCOUNTER` (`wOlivineCitySceneID` = 0) | none - it is unavoidable if you walk those cells | `setscene SCENE_OLIVINECITY_NOOP` at the end of either scene script |
Nothing in this section blocks the *walk* into Olivine City or up the
lighthouse. The only true forward gates are Surf (to leave Olivine westward),
the Jasmine-then-pharmacist flag chain, and Strength for the gym boulders.
## 4. Bot checklist
Preconditions carried in from earlier sections: `ENGINE_FOGBADGE`,
`ENGINE_PLAINBADGE`, `ENGINE_HIVEBADGE`, a mon that can learn `SURF`, a mon
that can learn `STRENGTH`, and ideally a stack of `BERRY` for Moomoo.

## 5. Port coverage
The Gen 2 port is engine-level and data-driven: every map header, `.blk`,
warp/coord/bg/object table and script bytecode in this section is read out of
the ROM by `src/import/RomExtractorGen2.lua` (`readMapEvents` at lines 785-862,
map records written at 973-976) rather than hand-transcribed, so "implemented"
below means the *opcodes and specials these particular scripts use* are
implemented, not that anyone has walked the maps.
| Beat | Port file | Status |
|---|---|---|
| Map headers, warps, coord events, bg events, object events for all 21 maps | `src/import/RomExtractorGen2.lua`, `src/world/gen2/Map.lua`, `src/world/gen2/World.lua` | implemented (generic, ROM-driven) |

| Phone registration and rematch tiers (Dana, Chad, Derek, Huey) | `src/core/gen2/Phone.lua`; `checkcellnum` / `askforphonenumber` in `src/script/gen2/Opcodes.lua` | implemented |
| Item balls (`OBJECTTYPE_ITEMBALL`) and hidden items (`BGEVENT_ITEM`) | `src/world/gen2/World.lua` (bg-event jumptable), `src/world/gen2/HiddenItems.lua` | implemented |
| Fruit trees (`fruittree FRUITTREE_ROUTE_38/39`) | `fruittree` opcode in `src/script/gen2/Opcodes.lua` | implemented |
| Moomoo Farm berry counter (`readmem`/`addval`/`writemem wMooMooBerries`) | `src/script/gen2/Vm.lua:711` and `:1657` (`scriptMem`), persisted by `src/core/gen2/Save.lua:187` | implemented - the port names this exact WRAM slot |
| `verbosegiveitem` / `giveitem` / `takeitem` / `checkitem` / `itemnotify` (Good Rod, HM04, TM13, Secretpotion, HM02, TM01) | `src/script/gen2/Opcodes.lua` | implemented |
| Moomoo Milk purchase (`checkmoney` / `takemoney` / `giveitem`) | `src/script/gen2/Opcodes.lua` | implemented |
| Marts: `MARTTYPE_STANDARD` (`MART_OLIVINE`) and `MARTTYPE_PHARMACY` (`MART_CIANWOOD`) | `src/ui/gen2/MartMenu.lua` (`PHARMACY` table at :212) | implemented |
| Shuckie: `special GiveShuckle` / `special ReturnShuckie`, OT MANIA id 518, happiness arms, `ENGINE_GOT_SHUCKIE_TODAY` | `src/script/gen2/Specials.lua:1191` onward | implemented |
| Cianwood photo studio `special PhotoStudio` | `src/script/gen2/Specials.lua:2122`, `src/ui/gen2/PhotoStudio.lua` | implemented |
| Jasmine cure scene: `special PlaySlowCry`, `special FadeOutToWhite`/`FadeInFromWhite`, `cry AMPHAROS`, `readvar VAR_FACING` branch | `src/script/gen2/Specials.lua` (998, 1000, 1079), `src/script/gen2/Opcodes.lua` | implemented |
| Surf field move + `ENGINE_FOGBADGE` gate | `src/world/gen2/FieldMoves.lua` (`surfFromMenu`, `TrySurfOW` port), driver `tests/drivers/gold_water_moves.lua` (its `WHIRL` fixture is literally `ROUTE_41` (22,11)) | implemented |
| Strength field move + `ENGINE_PLAINBADGE` gate + `STRENGTH_BOULDER` pushing | `src/world/gen2/FieldMoves.lua` (`strengthFromMenu`, the 3-way `TryStrengthOW` result at :689), driver `tests/drivers/gold_icepath_boulder.lua` | implemented |
| Fly field move + `ENGINE_STORMBADGE` gate, fly points | `src/world/gen2/FieldMoves.lua:330` (`flypoints.asm` transcribed), `:504` `flyFromMenu` | implemented |

| Chuck's boulder throw: `earthquake 80`, `set_sliding`/`big_step`/`fast_jump_step` | `earthquake` in `src/script/gen2/Opcodes.lua`, movement verbs in `src/script/gen2/Movement.lua` | implemented |
| Water wild encounters for Route 40 / 41 / Olivine / Cianwood, Gold-vs-Silver Mantine split | `src/battle/gen2/Encounter.lua`, tables from `RomExtractorGen2.lua` | implemented |
| Good Rod fishing (`FISHGROUP_SHORE` / `FISHGROUP_OCEAN`, `TimeFishGroups`) | `src/battle/gen2/Encounter.lua` (`Encounter.fish`), extractor `readRod` | implemented |
| Headbutt trees on Route 38/39 (`TREEMON_SET_FOREST`) | `src/battle/gen2/Encounter.lua:114` onward, `RomExtractorGen2.lua:3780` | implemented |
| **Rock Smash wild encounters (`RockMonMaps` -> `TREEMON_SET_ROCK`, i.e. Shuckle/Krabby on Route 40 and Cianwood City)** | `src/script/gen2/CallAsm.lua:526` explicitly stubs `RockMonEncounter` with "ROCK SMASH has no field-move path yet; RockMonMaps is unported"; `RomExtractorGen2.lua` extracts `TreeMonMaps` only | **missing** |
| Roaming / phone-call flavour beats the walkthrough mentions (Arnie, Liz, Todd, Mom's doll) | `src/core/gen2/Phone.lua` (incoming/special call machinery), `src/core/gen2/MomShopping.lua` | implemented (generic); no per-call verification done for this section |
| Any driver that actually walks Route 38 -> Cianwood end to end | - | **missing** - no `tests/drivers/gold_*` covers this stretch. `gold_water_moves.lua` touches `ROUTE_41` (22,11) only as a whirlpool fixture |
## 6. Unresolved / verify by hand
1. **"Beauty Olivia" on Route 38.** The walkthrough says "Now move southward
now to face Beauty Olivia." There is no `OLIVIA` in
`constants/trainer_constants.asm` (the `BEAUTY` class runs VICTORIA,
SAMANTHA, JULIE, JACLYN, BRENDA, CASSIE, CAROLINE, CARLENE, JESSICA,
RACHAEL, ANGELICA, KENDRA, VERONICA, JULIA, THERESA, VALERIE), no `OLIVIA`
string in `data/trainers/parties.asm`, and `maps/Route38.asm` has exactly
five trainer objects. This trainer does not exist in pokegold.
2. **"#100 Voltorb" listed under "Pokémon found in Olivine City".** Olivine
City has no grass encounter table at all, and its water table
(`data/wild/johto_water.asm:239`) is TENTACOOL / TENTACOOL / TENTACRUEL.
Voltorb is not reachable on this map by any table I could find. Unverified.
3. **"#213 Shuckle" listed under Route 40 *and* Route 41.** Route 40 is correct
but by Rock Smash, not by surfing: `data/wild/treemon_maps.asm:45` puts it
in `RockMonMaps` with `TREEMON_SET_ROCK` (10% SHUCKLE 15). Route 41 is
**not** in `RockMonMaps`, has `TREEMON_SET_NONE` for headbutt, and its
`Route41Rock` script is marked `; unreferenced` in the asm. Shuckle appears
unobtainable on Route 41.
4. **Swimmer Charlie's second Pokemon.** Walkthrough: "Level 21 Tentacool".
`data/trainers/parties.asm` `SwimmerMGroup` "CHARLIE" (`SWIMMERM` 4) reads
`db 21, SHELLDER / db 19, TENTACOOL / db 19, TENTACRUEL`. Level 19, not 21.
5. **Bird Keeper Denis's party order.** Walkthrough lists Spearow, Spearow,
Fearow; the asm order is `18 SPEAROW / 20 FEAROW / 18 SPEAROW`.
6. **Swimmer Kaylee** (`SWIMMERF` 3, 18 GOLDEEN / 20 GOLDEEN / 20 SEAKING) at
`ROUTE_41` (17,4) is a real trainer the walkthrough never mentions.
7. **Whether the x = 16/17 lighthouse pairs are one-way holes or two-way
passages.** The warp tables are symmetric (every pair points back at the
coordinates it came from), so warp data alone cannot tell you. Whichever it
is lives in the block collision for `TILESET_LIGHTHOUSE` and the `.blk`
files, which I did not decode. The walkthrough treats them as one-way drops
and the geometry is consistent with that, but treat "can I climb back up
through (16,7)?" as unverified.
8. **"You can avoid fighting the next trainer" (Bird Keeper Theo, 3F).** Theo
has sight range 3 at (3,9); whether a walkable lane exists outside that
cone depends on the 3F `.blk`, not the object table.
9. **The exact spot the walkthrough means by "Now, swim south onto Route 41"
and the "left side / right side" split.** Route 41's two branches are
geometry in `maps/Route41.blk`; the object coordinates above are the only
hard data. A bot should path by trainer coordinates rather than by the
prose.
10. **Phone-call timing claims** ("Arnie calls again", "Liz then calls you
about her Nidoran", "Todd will now call", "Mom calls saying she bought you
an adorable doll"). These come from `CheckPhoneCall` in
`engine/overworld/time.asm` plus `data/phone/*.asm`, not from any script in
these maps, and the walkthrough's own quoted note says the caller and topic
are random. Nothing in this section's asm schedules them.
11. **"3000G" from Chuck.** Prize money is computed from the trainer class base
in `data/trainers/attributes.asm` times the last mon's level, not written
anywhere in `maps/CianwoodGym.asm`. I did not verify the arithmetic.
12. **"TM23" under "Items found in Olivine City".** TM23 is Jasmine's gym
reward in `maps/OlivineGym.asm`, which belongs to section 09; nothing on
`MAP_OLIVINE_CITY` itself yields it.
