Section 11 - Team Rocket Hideout and Mahogany Town Gym

Source: ../section-11-team-rocket-hideout-and-mahogany-town-gym.txt (the FAQ's own heading is "17 > Team Rocket Hideout and Mahogany Town Gym")

Maps covered: MAP_MAHOGANY_TOWN, MAP_MAHOGANY_POKECENTER_1F, MAP_MAHOGANY_MART_1F, MAP_TEAM_ROCKET_BASE_B1F, MAP_TEAM_ROCKET_BASE_B2F, MAP_TEAM_ROCKET_BASE_B3F, MAP_MAHOGANY_GYM

Badges / key milestones in this section:

• EVENT_UNCOVERED_STAIRCASE_IN_MAHOGANY_MART - the hideout entrance exists
• EVENT_LEARNED_SLOWPOKETAIL, EVENT_LEARNED_RATICATE_TAIL - Giovanni's-office door
• EVENT_LEARNED_HAIL_GIOVANNI - transmitter-room door
• EVENT_GOT_HM06_WHIRLPOOL (HM06 = HM_WHIRLPOOL)
• EVENT_CLEARED_ROCKET_HIDEOUT + clearflag ENGINE_ROCKET_SIGNAL_ON_CH20
• ENGINE_GLACIERBADGE (GLACIERBADGE, badge 7) + EVENT_GOT_TM16_ICY_WIND (TM16 = TM_ICY_WIND)

Entry precondition, set in the previous section: maps/LakeOfRage.asm LakeOfRageLanceScript.AgreedToHelp runs clearevent EVENT_MAHOGANY_MART_LANCE_AND_DRAGONITE, setevent EVENT_DECIDED_TO_HELP_LANCE, setmapscene MAHOGANY_MART_1F, SCENE_MAHOGANYMART1F_LANCE_UNCOVERS_STAIRS. Without that scene set, the mart is an ordinary shop and there is no staircase.

2. Maps

MAP_MAHOGANY_TOWN

• Script: maps/MahoganyTown.asm
• Blocks: maps/MahoganyTown.blk
• Header: data/maps/maps.asm:74 -> map MahoganyTown, TILESET_JOHTO, TOWN, LANDMARK_MAHOGANY_TOWN, MUSIC_CHERRYGROVE_CITY, FALSE, PALETTE_AUTO, FISHGROUP_SHORE
• Dimensions: constants/map_constants.asm -> map_const MAHOGANY_TOWN, 10, 9 (group MAHOGANY = 2, map id 7); 10x9 blocks = 20x18 map cells
• Connections: data/maps/attributes.asm:152-155 -> north Route43, west Route42, east Route44
• Scene ids (declared inline by scene_script): SCENE_MAHOGANYTOWN_TRY_RAGECANDYBAR = 0, SCENE_MAHOGANYTOWN_NOOP = 1
• Callback: MAPCALLBACK_NEWMAP, MahoganyTownFlypointCallback -> setflag ENGINE_FLYPOINT_MAHOGANY

SCENE_MAHOGANYTOWN_TRY_RAGECANDYBAR (0)	19	9	MahoganyTownTryARageCandyBarScript	same

The script never calls setscene, so the pitch re-fires every time you cross x=19 until RadioTowerRocketsScript (engine/events/std_scripts.asm:263) runs setmapscene MAHOGANY_TOWN, SCENE_MAHOGANYTOWN_NOOP.

Object-event flag polarity (verified in engine/overworld/map_objects_2.asm CheckObjectFlag): the flag being set masks (hides) the object; -1 means always visible. So EVENT_MAHOGANY_TOWN_POKEFAN_M_BLOCKS_GYM clear = the fisher stands on 6,14, one cell south of the gym warp at 6,13, blocking it. That flag is set by RocketBaseElectrodeScript at the end of the hideout, which is the real gate on the Mahogany gym (see section 3).

Scripts of interest

MahoganyMart1FLanceUncoversStaircaseScript (45:4046), reached as scene_script ... SCENE_MAHOGANYMART1F_LANCE_UNCOVERS_STAIRS via sdefer, so it fires on map entry without any player input:

1. Dragonite big_step LEFT / big_step RIGHT into the Black Belt, disappear MAHOGANYMART1F_DRAGONITE
2. Lance walks over (MahoganyMart1FLanceApproachPlayerMovement), follow MAHOGANYMART1F_LANCE, PLAYER, shoves the pharmacist aside
3. changeblock 6, 2, $1e + refreshmap + setevent EVENT_UNCOVERED_STAIRCASE_IN_MAHOGANY_MART
4. disappear MAHOGANYMART1F_LANCE, setscene SCENE_MAHOGANYMART1F_NOOP

changeblock's operands are map cell coordinates, not block coordinates (Script_changeblock at engine/overworld/scripting.asm:2031 adds 4 to each and calls GetBlockLocation, which halves them - home/map.asm:2099). 6,2 is therefore block (3,1), covering cells (6..7, 2..3); block $1e in data/tilesets/traditional_house_collision.asm is FLOOR, FLOOR, FLOOR, LADDER, putting the LADDER on cell 7,3 - exactly the warp row above.

Marts: MahoganyMart1FPharmacistScript -> pokemart MARTTYPE_STANDARD, MART_MAHOGANY_1 (closed once EVENT_DECIDED_TO_HELP_LANCE is set), MahoganyMart1FGrannyScript -> pokemart MARTTYPE_STANDARD, MART_MAHOGANY_2.

MAP_TEAM_ROCKET_BASE_B1F

• Script: maps/TeamRocketBaseB1F.asm (45:430c TeamRocketBaseB1F_MapScripts)
• Blocks: maps/TeamRocketBaseB1F.blk
• Header: data/maps/maps.asm:119 -> TILESET_UNDERGROUND, DUNGEON, LANDMARK_MAHOGANY_TOWN, MUSIC_ROCKET_HIDEOUT, TRUE, PALETTE_DAY, FISHGROUP_SHORE
• Dimensions: map_const TEAM_ROCKET_BASE_B1F, 15, 9 (group 3, map id 41) = 30x18 cells
• Scene ids: SCENE_TEAMROCKETBASEB1F_TRAPS = 0 (the only one)
• Callback: MAPCALLBACK_OBJECTS, TeamRocketBaseB1FHideSecurityGruntCallback -> disappear TEAMROCKETBASEB1F_ROCKET1 (the camera grunt is parked off-screen at 0,0 and teleported in by moveobject)

The whole floor is one connected walkable region (flood-filled from maps/TeamRocketBaseB1F.blk against data/tilesets/underground_collision.asm).

The Electrodes on the right (22,5/7/9) mirror the left three and share their flags; RocketElectrodeN disappears both of a pair, so Lance's three "count" without ever being battled.

Scripts of interest

• LanceHealsCommon (45:4d4c): special FadeOutToWhite, playsound SFX_FULL_HEAL, special HealParty, special FadeInFromWhite, setscene SCENE_TEAMROCKETBASEB2F_ROCKET_BOSS, setevent EVENT_LANCE_HEALED_YOU_IN_TEAM_ROCKET_BASE, then readvar VAR_FACING picks one of two exit movements and disappear TEAMROCKETBASEB2F_LANCE. This is a hard ordering dependency: the boss ambush coord events only exist on scene 1, so the transmitter room cannot be entered until Lance has healed you.
• TeamRocketBaseB2FLockedDoor (45:4e8f): conditional_event on EVENT_OPENED_DOOR_TO_ROCKET_HIDEOUT_TRANSMITTER; .Script checks EVENT_LEARNED_HAIL_GIOVANNI. If known: playsound SFX_ENTER_DOOR, changeblock 14, 12, $07, refreshmap, setevent EVENT_OPENED_DOOR_TO_ROCKET_HIDEOUT_TRANSMITTER.
• RocketBaseBossFScript (45:4c67): cutscene, then loadtrainer EXECUTIVEF, EXECUTIVEF_2 + startbattle; sets EVENT_TEAM_ROCKET_BASE_B2F_EXECUTIVE, ..._GRUNT_WITH_EXECUTIVE, ..._LANCE, EVENT_BEAT_ROCKET_EXECUTIVEF_2; then setscene SCENE_TEAMROCKETBASEB2F_ELECTRODES, clearevent EVENT_TEAM_ROCKET_BASE_B2F_LANCE (re-showing Lance), the Electrode briefing, disappear TEAMROCKETBASEB2F_LANCE.
• RocketElectrode1/2/3: cry ELECTRODE, loadwildmon ELECTRODE, 23, startbattle. iftrue TeamRocketBaseB2FReloadMap covers the "you lost/fled" path. After all three events are set, the player is auto-walked out by RocketBasePlayerLeavesElectrodesMovement1/2/3 into RocketBaseElectrodeScript. No BATTLETYPE_* is armed here, so these are catchable ordinary wild battles.

The Murkrow the walkthrough talks to is the object using SPRITE_MOLTRES at 7,2; its script is RocketBaseMurkrow and its text says MURKROW. The sprite constant is the generic large-bird overworld sprite, not a Moltres encounter.

Scripts of interest

• LanceGetPasswordScript (45:5cb4): both the sdefer scene script for scene 0 and the Lance object's own script. Runs on entry to the right region, prints LanceGetPasswordText, disappear TEAMROCKETBASEB3F_LANCE (which sets EVENT_TEAM_ROCKET_BASE_B3F_LANCE_PASSWORDS), setscene SCENE_TEAMROCKETBASEB3F_RIVAL_ENCOUNTER.

• RaticateTailGrunt -> trainer GRUNTM, GRUNTM_28, EVENT_BEAT_ROCKET_GRUNTM_28, ...; GruntM28Script does setevent EVENT_LEARNED_RATICATE_TAIL. Sight 3, SPINRANDOM_FAST (the "spinning Team Rocket member").
• TeamRocketBaseB3FLockedDoor (45:5da9): .Script requires EVENT_LEARNED_SLOWPOKETAIL and EVENT_LEARNED_RATICATE_TAIL; on success changeblock 10, 8, $07, refreshmap, setevent EVENT_OPENED_DOOR_TO_GIOVANNIS_OFFICE.

Sliding rule (engine/overworld/player_movement.asm): CheckIceTile on the tile you land on -> STEP_ICE; .CheckForced / CheckStandingOnIce re-injects the same d-pad direction, so a single press slides until you land on a non-ice tile, hit a wall, or hit an NPC.

Simulating that rule against the grid above (NPCs treated as blockers) reproduces the walkthrough's directions exactly:

from	press	lands on	who
4,17 (warp)	UP	4,16	-
4,16	LEFT, LEFT, LEFT	3,16 -> 2,16 -> 0,16	faces Boarder Ronald 0,17
0,16	UP,UP,RIGHT,DOWN,LEFT	0,8 -> 0,2 -> 6,2 -> 6,5 -> 2,5	faces Boarder Douglas 2,4
2,5	DOWN,RIGHT	2,10 -> 5,10	faces Boarder Brad 5,9
5,10	RIGHT,DOWN	9,10 -> 9,16	faces Skier Clarissa 9,17
9,16	UP,UP,LEFT	9,10 -> 9,7 -> 4,7	faces Skier Roxanne 4,6
4,7	DOWN	4,14	back toward the exit
2,14 ("just left of the left pillar", pillar block at 3,14/3,15)	UP,UP,RIGHT,DOWN,LEFT,UP,RIGHT	2,10 -> 2,5 -> 6,5 -> 6,13 -> 3,13 -> 3,4 -> 5,4	standing directly below Pryce 5,3

Reaching 2,14 from the entrance: UP (to 4,16), LEFT (3,16), LEFT (2,16), UP (2,15), UP (2,14) - 2,15/2,16/2,14 are ordinary floor, not ice, so those are single steps.

Scripts of interest

4. readvar VAR_BADGES; scall MahoganyGymActivateRockets - ifequal 7, .RadioTowerRockets / ifequal 6, .GoldenrodRockets. Badge count is read after GLACIERBADGE is set, so the normal route (Glacier as the 7th badge) takes jumpstd RadioTowerRocketsScript (engine/events/std_scripts.asm:255), which sets ENGINE_ROCKETS_IN_RADIO_TOWER, EVENT_GOLDENROD_CITY_CIVILIANS, EVENT_RADIO_TOWER_BLACKBELT_BLOCKS_STAIRS, EVENT_MAHOGANY_TOWN_POKEFAN_M_BLOCKS_EAST, specialphonecall SPECIALCALL_WEIRDBROADCAST, and setmapscene MAHOGANY_TOWN, SCENE_MAHOGANYTOWN_NOOP. Skipping Jasmine first (Glacier as the 6th) takes GoldenrodRocketsScript instead, which only clears EVENT_GOLDENROD_CITY_ROCKET_TAKEOVER.
5. .FightDone: if EVENT_GOT_TM16_ICY_WIND is set -> farewell text. Otherwise setevent EVENT_BEAT_SKIER_ROXANNE / _CLARISSA / _BOARDER_RONALD / _BRAD / _DOUGLAS (so the five gym trainers never battle again), PryceText_GlacierBadgeSpeech, verbosegiveitem TM_ICY_WIND, setevent EVENT_GOT_TM16_ICY_WIND.

5. Port coverage

Beat	Port file	Status
Map headers / warps / coord events / bg events / objects for all six maps	src/import/RomExtractorGen2.lua, src/world/gen2/Map.lua	implemented (generic extraction, nothing map-specific needed)
Map scenes + sdefer scene scripts	src/world/gen2/World.lua (World:scene, mapScenes), src/script/gen2/Vm.lua (sdefer, setscene, setmapscene)	implemented
Coord-event trip-wires	src/world/gen2/World.lua (coord event dispatch)	implemented
changeblock (mart staircase, both password doors)	src/script/gen2/Vm.lua:1006 - the comment cites MahoganyMart1F's changeblock 6, 2, $1e and cell (7,3) by name	implemented
BGEVENT_IFNOTSET / conditional_event (both password doors)	src/world/gen2/World.lua:5147 World:bgEventAt only matches (ev.kind or 0) == 0; src/world/gen2/HiddenItems.lua handles kind 7	missing - pressing A on the transmitter door or Giovanni's door does nothing in the port
Ice sliding (STEP_ICE, CheckStandingOnIce forced d-pad)	src/world/gen2/Permissions.lua:128 ICE exists but is only consumed by FieldMoves.canEncounterWildMon; World:movePlayer picks step frames from Bike.stepFrames only	missing - Mahogany Gym floor behaves as ordinary floor, so the puzzle and the trainer sight lines are wrong
Trainer sight range / approach	src/world/gen2/Trainers.lua (Trainers.sees, Trainers.approach)	implemented (sight 0 on GruntF5 falls out naturally)
itemball / hiddenitem	src/script/gen2/CallAsm.lua, src/world/gen2/HiddenItems.lua	implemented
verbosegiveitem HM_WHIRLPOOL	src/script/gen2/Vm.lua, src/script/gen2/Opcodes.lua	implemented
Whirlpool field move + GLACIERBADGE gate	src/world/gen2/FieldMoves.lua:109 (WHIRLPOOL = "GLACIER"), .somethingToWhirlpool, .whirlpoolFromMenu, .tryWhirlpoolOW, WHIRLPOOL_BLOCKS	implemented
loadwildmon + BATTLETYPE_TRAP	src/world/gen2/World.lua:4587 (names "TRAP 9 (the Rocket base)"), src/script/gen2/Vm.lua:699	implemented

jumpstd (TeamRocketOathScript, GymStatue1/2Script, PokecenterSignScript, RadioTowerRocketsScript)	src/script/gen2/Vm.lua:742, data/generated/std_scripts.lua via World.lua:635	implemented (generic)
readvar VAR_BADGES for MahoganyGymActivateRockets	src/world/gen2/World.lua:117,1240	implemented
specialphonecall SPECIALCALL_WEIRDBROADCAST	src/script/gen2/Vm.lua:1364 stores the id; src/core/gen2/Phone.lua delivers	implemented
ENGINE_ROCKET_SIGNAL_ON_CH20 radio behaviour	src/ui/gen2/Pokegear.lua:816-821, 1097	implemented
Driver coverage for this stretch	tests/drivers/gold_*.lua - none touches Mahogany, the hideout or Pryce (gold_icepath_boulder.lua is the only Mahogany-adjacent one, and it is Ice Path boulders)	missing

The two "missing" rows are the blocking ones: without BGEVENT_IFNOTSET the hideout cannot be completed, and without ice sliding the gym cannot be crossed.

6. Unresolved / verify by hand

• Floor labels in the walkthrough are wrong past the first password. It says "go up the stairs at the upper-right part of the floor, then head left on Negative Floor 2 ... Head up the stairs to Negative Floor 1. Head right and then before you reach the locked door, your rival will come." The rival coord event (8,10) and Giovanni's office are both on B3F, not B1F. The route is B3F(right) -> B2F(top) -> B3F(left). Verified by flood-filling maps/TeamRocketBaseB2F.blk / maps/TeamRocketBaseB3F.blk: the four B2F warps and four B3F warps sit in disconnected rooms, and B2F warp 2 (3,2) reaches B3F (3,2) which is the region containing 8,10.
• Boarder Ronald's party order. Walkthrough lists Seel 24 / Seel 24 / Dewgong 25; data/trainers/parties.asm BOARDER (1) is SEEL 24, DEWGONG 25, SEEL 24. Same three mon, different lead order. Same class of discrepancy for GRUNTM_18 (walkthrough Rattata/Rattata/Zubat, asm Rattata/Zubat/Rattata).
• Item list is incomplete. The walkthrough's "Items in the Team Rocket Hideout" block lists six; the asm has ten: the six named plus FULL_HEAL and DIRE_HIT item balls on B3F (mentioned later in the prose) and two hidden items the walkthrough never mentions - REVIVE at B1F (3,11) and FULL_HEAL at B2F (26,7).
• "Every time you pass one of those statues, two Team Rocket grunts will fight you" is right, but the walkthrough implies only two statues on the first floor. There are five (bg_event at 24,1, 6,1, 24,5, 8,15, 22,15) with eight trigger cells, i.e. up to ten grunt battles if none are skipped.
• EVENT_TEAM_ROCKET_BASE_POPULATION is dead. It is the shared visibility flag of eleven base NPCs and is read by all eight SecurityCamera* scripts, but a full-tree grep finds no setevent, clearevent or disappear that writes it. Those checkevent ... iftrue NoSecurityCamera arms therefore never take, and the Rocket NPCs stay on the maps forever - including after the hideout is cleared. Flagged in case a bot author expects the base to empty out.
• Lance's three right-hand Electrodes are never battled. RocketElectrodeN disappears both members of a mirrored pair, and the objects at 22,5/22,7/22,9 point at the no-op ObjectEvent script. The walkthrough's "Lance runs to the right to take the Electrodes on the right" is flavour; the game just hides them.
• Exact reachability of 19,11 (the secret switch) was checked by collision (19,11 is a WALL, 19,12 is FLOOR and in the single B1F region), but the in-game facing direction for the BGEVENT_READ was not observed running - the bg event type is BGEVENT_READ, not BGEVENT_UP, so any adjacent facing should work; worth confirming on hardware if a driver misses it.
• The gym slide table in section 2 was produced by simulating engine/overworld/player_movement.asm's ice rule against the decoded maps/MahoganyGym.blk, treating NPCs as blockers. It reproduces every direction string in the walkthrough, but it has not been executed in an emulator.
