Section 12 - Team Rocket Radio Tower

Source: ../section-12-team-rocket-radio-tower.txt (the FAQ's own heading is "18 > Team Rocket Radio Tower") Maps covered: MAP_GOLDENROD_CITY, MAP_RADIO_TOWER_1F, MAP_RADIO_TOWER_2F, MAP_RADIO_TOWER_3F, MAP_RADIO_TOWER_4F, MAP_RADIO_TOWER_5F, MAP_GOLDENROD_UNDERGROUND, MAP_GOLDENROD_UNDERGROUND_SWITCH_ROOM_ENTRANCES, MAP_GOLDENROD_UNDERGROUND_WAREHOUSE, MAP_GOLDENROD_DEPT_STORE_B1F

Badges / key milestones in this section:

  • No badge. The section is bracketed by two key items and one story flag: BASEMENT_KEY (from the fake director, RADIO_TOWER_5F), CARD_KEY (from the real director, GOLDENROD_UNDERGROUND_WAREHOUSE), and EVENT_CLEARED_RADIO_TOWER + RAINBOW_WING (Gold) / SILVER_WING (Silver) from RadioTower5FRocketBossScript.
  • The rival's fourth battle (RIVAL1_4_*) happens in the middle of it.
  • Entry condition is the 7th badge, not any item: see section 3.

Spill into the next section: the walkthrough's closing party-level lists and the video link's mention of Route 44 belong to whatever section follows; nothing after RadioTower5FRocketBossScript is covered here.

None of the city Rockets are trainers - they are all jumptextfaceplayer.

Scripts of interest

  • GoldenrodCityFlypointCallback (MAPCALLBACK_NEWMAP): setflag ENGINE_FLYPOINT_GOLDENROD / setflag ENGINE_REACHED_GOLDENROD. This is why the walkthrough can say "fly to the city".

Scripts of interest

  • RadioTower1FReceptionistScript - checkflag ENGINE_ROCKETS_IN_RADIO_TOWER; if set, the "no tours today" line. Pure flavour, no gate.
  • TrainerGruntM3 - trainer GRUNTM, GRUNTM_3, EVENT_BEAT_ROCKET_GRUNTM_3, .... Sight range 3 facing down from (14,1): he intercepts the walk to warp 3 at (15,0).
  • RadioTower1FRadioCardWomanScript / RadioTower1FLuckyNumberManScript are the Radio Card quiz and the Lucky Number Show. Both are hidden while EVENT_GOLDENROD_CITY_CIVILIANS is set, i.e. for the whole of this section.

Scripts of interest

  • RadioTower2FBlackBelt1Script at (0,1) is the pre-takeover stairs blocker ("Authorized personnel only beyond this point"). RadioTowerRocketsScript (engine/events/std_scripts.asm:255) does setevent EVENT_RADIO_TOWER_BLACKBELT_BLOCKS_STAIRS, and a SET object event flag MASKS the object (CheckObjectFlag, engine/overworld/map_objects_2.asm:32), so during the takeover he is gone and warp 1 at (0,0) is walkable.
  • Walkthrough order on this floor is TrainerGruntF2 (10,5) -> TrainerGruntM5 (8,4) -> TrainerGruntM6 (4,1) -> TrainerGruntM4 (1,4).

MAP_RADIO_TOWER_3F

TrainerGruntM9 at (16,6) sits behind the shutter: he is only reachable on the second pass.

Scripts of interest

  • RadioTower3FCardKeyShutterCallback (callback MAPCALLBACK_TILES, label at 43:5be1): checkevent EVENT_USED_THE_CARD_KEY_IN_THE_RADIO_TOWER; if true, changeblock 14, 2, $2a (open shutter) and changeblock 14, 4, $01 (floor). This is what makes the opening persist across map loads.
  • CardKeySlotScript (43:5c91, exported with :: so other maps can reach it): writes RadioTower3FCardKeySlotText, then checkevent EVENT_USED_THE_CARD_KEY_IN_THE_RADIO_TOWER (already used -> just close), else checkitem CARD_KEY. With the key: InsertedTheCardKeyText, setevent EVENT_USED_THE_CARD_KEY_IN_THE_RADIO_TOWER, playsound SFX_ENTER_DOOR, the same two changeblocks, refreshmap.
  • RadioTower3FCooltrainerFScript - after EVENT_CLEARED_RADIO_TOWER, verbosegiveitem TM_SUNNY_DAY and setevent EVENT_GOT_SUNNY_DAY_FROM_RADIO_TOWER. The walkthrough does not mention this reward.

Scripts of interest - the shutter puzzle

This is the load-bearing part of the section, and the asm behaves differently from how the walkthrough describes it.

The eleven shutters are declared at the top of the file by the local ugdoor_def macro (coordinates are changeblock coordinates, i.e. the same cell units the script uses):

door x, y closed block open block second half (x, y, closed, open)
1 16, 6 $3e $2d -
2 10, 6 $3e $2d -
3 2, 6 $3e $2d -
4 2, 10 $3e $2d -
5 10, 10 $3e $2d -
6 16, 10 $3e $2d -
7 12, 6 $3f $2a 12, 8, $3d, $2d
8 6, 6 $3f $2a 6, 8, $3d, $2d
9 12, 10 $3f $2a 12, 12, $3d, $2d
10 6, 10 $3f $2a 6, 12, $3d, $2d
11 18, 10 $3f $2a 18, 12, $3d, $2d

Switch1Script / Switch2Script / Switch3Script each readmem wUndergroundSwitchPositions (01:d6a8), addval +N when turning ON or addval -N when turning OFF (N = 1, 2, 3 respectively), writemem it back, set/clear EVENT_SWITCH_N, then sjump GoldenrodUndergroundSwitchRoomEntrances_UpdateDoors (46:4c57).

EmergencySwitchScript at (20,11) is different: ON does setval 7 (not an add), sets EVENT_EMERGENCY_SWITCH and all three EVENT_SWITCH_*; OFF does setval 0 and clears all four.

..._UpdateDoors dispatches on the stored byte. Crucially each position only touches SOME doors - the rest keep whatever state the previous position left them in, which is the entire reason order matters:

value opens closes untouched
0 - 1..11 -
1 1, 7, 10 6, 8, 9, 11 2, 3, 4, 5
2 2, 8, 9 5, 7, 10, 11 1, 3, 4, 6
3 3, 7, 10 4, 8, 9, 11 1, 2, 5, 6
4 4, 8, 9 3, 7, 10, 11 1, 2, 5, 6
5 5, 7, 10 2, 8, 9, 11 1, 3, 4, 6
6 6, 8, 9, 11 1, 7, 10 2, 3, 4, 5
7 (emergency) 3, 5, 6, 8, 9, 11 1, 2, 4, 7, 10 -

The emergency arm ends with setval 6 / writemem, so the stored byte becomes 6 afterwards even though the door layout is the emergency one.

Consequences a bot needs (derived by tracing the table, from the reset state where the stored byte is 0 and all doors closed):

  • Flip 1, then 2, then 3 (values 1 -> 3 -> 6). Final open doors: 3, 6, 8, 9, 11. Door 8 at (6,6)/(6,8) is what lets you drop south from the switch-3 alcove to TrainerBurglarEddie at (4,8).
  • From there flip 3 off then 2 off (values 6 -> 3 -> 1). Final open doors: 1, 3, 7, 10. Door 7 at (12,6)/(12,8) is what opens the way to the Full Heal ball at (14,9).
  • Reset (leave via a warp so the MAPCALLBACK_NEWMAP reset runs) and flip 3, then 2, then 1 (values 3 -> 5 -> 6). Final open doors: 3, 5, 6, 8, 9, 11 - the same set as 1/2/3 PLUS door 5 at (10,10). Door 5 is the one that opens the route south to TrainerBurglarDuncan (9,12), TrainerGruntF3 (19,12) and the warehouse warps at (22,10)/(23,10).

So the walkthrough's "turn them on in the opposite direction" is correct in effect, but the mechanism is not "order is remembered": the stored byte is a plain SUM (1+2+3 = 3+2+1 = 6), and what differs is which doors the intermediate positions left untouched.

Scripts of interest

  • GoldenRodDeptStoreB1FClearBoxesCallback (MAPCALLBACK_TILES) - checkevent EVENT_RECEIVED_CARD_KEY -> changeblock 16, 4, $0d (floor). Then the crate layout: EVENT_GOLDENROD_DEPT_STORE_B1F_LAYOUT_2 -> changeblock 4, 10, $0d; ..._LAYOUT_3 -> changeblock 10, 12, $0d; default (LAYOUT_1) -> changeblock 10, 8, $0d.
  • GoldenRodDeptStoreUnblockCallback (MAPCALLBACK_NEWMAP) - clearevent EVENT_GOLDENROD_UNDERGROUND_WAREHOUSE_BLOCKED_OFF. That event starts SET (InitializeEventsScript, engine/events/std_scripts.asm:518) and is what GoldenrodDeptStoreElevatorScript (maps/GoldenrodDeptStoreElevator.asm:15) checks before rotating the crate layout - so the layout only ever changes once you have entered B1F on foot from the warehouse.

Neither Executive fight nor the fake director fight has a loss text (winlosstext ..., 0), so a whiteout there is a normal blackout, not a scripted loss. The rival fight DOES have one (UndergroundRivalLossText).

Wild encounters

None. Grepping data/wild/johto_grass.asm, johto_water.asm, fish.asm and treemons.asm for RADIO_TOWER or GOLDENROD returns nothing: every map in this section is INDOOR or DUNGEON with no wild table.

That script sets ENGINE_ROCKETS_IN_RADIO_TOWER, clears EVENT_RADIO_TOWER_ROCKET_TAKEOVER (spawns every Grunt) and queues SPECIALCALL_WEIRDBROADCAST. ifequal 6 instead runs GoldenrodRocketsScript, which only clears EVENT_GOLDENROD_CITY_ROCKET_TAKEOVER.

No HM field move is required anywhere in this section - no Cut, Surf, Strength, Whirlpool, Waterfall or Flash check appears in any of these maps.

4. Bot checklist

Coordinates are asm cell coordinates. "talk" means face the target and press A.

Pass 1 - Radio Tower up to the Basement Key:

  1. MAP_GOLDENROD_CITY: precondition ENGINE_ROCKETS_IN_RADIO_TOWER set (7 badges). Walk to (5,15), warp 12 -> RADIO_TOWER_1F (2,7).
  2. RADIO_TOWER_1F: walk toward (15,0). TrainerGruntM3 at (14,1) sights you (range 3, facing down). Battle GRUNTM_3. Post: EVENT_BEAT_ROCKET_GRUNTM_3.
  3. Warp 3 at (15,0) -> RADIO_TOWER_2F (15,0).
  4. RADIO_TOWER_2F: walk left. Fight in this order: TrainerGruntF2 (10,5), TrainerGruntM5 (8,4), TrainerGruntM6 (4,1), TrainerGruntM4 (1,4). Precondition for all: EVENT_RADIO_TOWER_ROCKET_TAKEOVER clear.
  5. Warp 1 at (0,0) -> RADIO_TOWER_3F (0,0).
  6. RADIO_TOWER_3F: TrainerGruntM8 (6,2), TrainerGruntM7 (5,1), TrainerScientistMarc (9,6, sight 5). Do NOT try (14,2) yet - no Card Key.
  7. Warp 2 at (7,0) -> RADIO_TOWER_4F (9,0).
  8. RADIO_TOWER_4F: TrainerGruntM10 (5,6), TrainerScientistRich (4,2).
  9. Warp 1 at (0,0) -> RADIO_TOWER_5F (0,0). Walk DOWN to (0,3): coord event fires FakeDirectorScript on scene 0. Battle EXECUTIVEM_3 (6 mons, four of them know Selfdestruct/Explosion). Post: BASEMENT_KEY in bag, EVENT_BEAT_ROCKET_EXECUTIVEM_3, 5F scene = 1.
  10. Retrace: 5F warp 1 -> 4F warp 1 -> 4F warp 2 (9,0) -> 3F warp 2 -> 3F warp 1 (0,0) -> 2F warp 1 -> 2F warp 2 (15,0) -> 1F warp 3 -> 1F warps 1/2 (2,7) -> GOLDENROD_CITY (5,15).

Pass 2 - Underground to the Card Key:

  1. GOLDENROD_CITY: heal at warp 7 (15,27) if wanted. Walk to (9,5), warp 14 -> GOLDENROD_UNDERGROUND_SWITCH_ROOM_ENTRANCES (20,29).
  2. Walk to (21,25), warp 7 -> GOLDENROD_UNDERGROUND (3,2).
  3. Optional: haircut brothers at (7,14)/(7,15) (day-gated); Coin Case ball at (7,25) if not taken.
  4. Walk to the tile below/beside (18,6) and A-press it: BasementDoorScript with BASEMENT_KEY -> EVENT_USED_BASEMENT_KEY. Then step onto (18,6) -> warp 3 -> GOLDENROD_UNDERGROUND (21,31).
  5. Walk to (22,27), warp 6 -> GOLDENROD_UNDERGROUND_SWITCH_ROOM_ENTRANCES (23,3). SAVE HERE (the walkthrough's advice; the rival battle is losable).
  6. Walk west to (19,4) or (19,5): UndergroundRivalScene1/2 fires on scene 0. Battle RIVAL1, member RIVAL1_4_CHIKORITA / _CYNDAQUIL / _TOTODILE picked by which starter you took. Post: EVENT_RIVAL_GOLDENROD_UNDERGROUND, scene -> 1. (Side effect: EVENT_RIVAL_BURNED_TOWER + Burned Tower scene.)
  7. Fight TrainerGruntM13 (17,2), TrainerGruntM11 (11,2), TrainerGruntM25 (3,2) - west along the top corridor.
  8. Switch byte starts at 0. A-press Switch1Script at (16,1) -> ON (byte 1), then Switch2Script at (10,1) -> ON (byte 3), then Switch3Script at (2,1) -> ON (byte 6). Doors 3, 6, 8, 9, 11 now open.
  9. Go south through door 8 at (6,6)/(6,8) to TrainerBurglarEddie at (4,8). Battle BURGLAR EDDIE.
  10. A-press Switch3 (2,1) -> OFF (byte 3), then Switch2 (10,1) -> OFF (byte 1). Doors 1, 3, 7, 10 open. Take the FULL_HEAL ball at (14,9).
  11. Leave and re-enter the map so ..._ResetSwitchesCallback zeroes everything (e.g. warp 1 at (23,3) into GOLDENROD_UNDERGROUND and back through (22,27)).
  12. Now A-press Switch3 (2,1) ON (byte 3), Switch2 (10,1) ON (byte 5), Switch1 (16,1) ON (byte 6). Doors 3, 5, 6, 8, 9, 11 open - door 5 at (10,10) is the new one.
  13. Go south through door 5 to TrainerBurglarDuncan (9,12), then east to TrainerGruntF3 (19,12). Optionally the SMOKE_BALL ball at (1,12) and the two hidden items at (8,9) and (1,8).
  14. Warps 2/3 at (22,10)/(23,10) -> GOLDENROD_UNDERGROUND_WAREHOUSE (2,12).
  15. Warehouse: TrainerGruntM14 (8,15), MAX_ETHER ball at (18,15), TrainerGruntM15 (14,3). Optional side trip: warp 3 at (17,2) -> GOLDENROD_DEPT_STORE_B1F (17,2), take AMULET_COIN at (14,2), warp back.
  16. TrainerGruntM24 (9,8). Take TM_SLEEP_TALK (TM35) at (13,9). Talk to the Director at (12,8): verbosegiveitem CARD_KEY, post EVENT_RECEIVED_CARD_KEY + EVENT_GOLDENROD_DEPT_STORE_B1F_LAYOUT_1.
  17. Exit back through warps 1/2 (2,12)/(3,12). If a shutter blocks the way out, A-press EmergencySwitchScript at (20,11) (forces doors 3,5,6,8,9,11 open). Then warp 1 at (23,3) or warps 8/9 at (20,29)/(21,29) to leave.

Pass 3 - retake the tower:

  1. GOLDENROD_CITY -> RADIO_TOWER_1F (warp 12) -> 2F -> 3F as in steps 2-5.
  2. RADIO_TOWER_3F: stand at (14,3) FACING UP and press A on (14,2) (BGEVENT_UP). CardKeySlotScript -> EVENT_USED_THE_CARD_KEY_IN_THE_RADIO_TOWER, blocks (14,2)/(14,4) rewritten.
  3. Walk east/south to TrainerGruntM9 at (16,6). Battle GRUNTM_9.
  4. Warp 3 at (17,0) -> RADIO_TOWER_4F (17,0). Battle TrainerGruntF4 (12,4), then TrainerExecutivem2 (14,1) who guards warp 3.
  5. Warp 3 at (12,0) -> RADIO_TOWER_5F (12,0). Battle TrainerExecutivef1 (17,2).
  6. Walk to (16,5): coord event on scene 1 fires RadioTower5FRocketBossScript. The script moves the PLAYER two cells left first. Battle EXECUTIVEM_1.
  7. Post-conditions: EVENT_CLEARED_RADIO_TOWER, ENGINE_ROCKETS_IN_RADIO_TOWER cleared, all Rocket objects masked, civilians restored, Blackthorn gym blocker swapped, RAINBOW_WING (Gold) or SILVER_WING (Silver) received, 5F scene -> 2.
  8. Optional pickups now unlocked: TM_SUNNY_DAY from the 3F cooltrainer at (11,3); PINK_BOW from DJ Mary at (14,6) on 4F.

5. Port coverage

The Gen 2 side of this repo is data-driven: maps, warps, coord events, bg events, object events and scripts all come out of src/import/RomExtractorGen2.lua and run through src/script/gen2/Vm.lua, so "implemented" below means the generic machinery this section needs exists, not that anyone has walked the section.

Beat Port file Status

Card Key slot (bg_event ... BGEVENT_UP) src/world/gen2/World.lua:5147 World:bgEventAt matches only (ev.kind or 0) == 0, i.e. BGEVENT_READ missing - the directional bg-event arms (BGEVENT_UP/DOWN/RIGHT/LEFT, and BGEVENT_IFSET/IFNOTSET/COPY) are not dispatched, so CardKeySlotScript can never fire and the 3F shutter cannot be opened. This blocks pass 3 entirely.
Ground item balls (OBJECTTYPE_ITEMBALL) extracted as obj.itemball (src/import/RomExtractorGen2.lua:2968) but nothing consumes it: World:interact (src/world/gen2/World.lua:5257) has arms for trainers, strength boulders, scriptKey NPCs, BGEVENT_READ and BGEVENT_ITEM only missing - Smoke Ball, Full Heal, Max Ether, TM35 Sleep Talk and Amulet Coin are all unobtainable. src/script/gen2/CallAsm.lua:547 stubs TryReceiveItem on the assumption this path exists.

6. Unresolved / verify by hand

  1. "He gives you a Clear Bell." The asm does not give a Clear Bell here. RadioTower5FRocketBossScript (maps/RadioTower5F.asm:122-139) branches on checkver: Silver gets SILVER_WING, Gold gets RAINBOW_WING. The Clear Bell is a Crystal item and does not appear in this script. Treat the walkthrough line as wrong for Gold/Silver.
  2. Switch ordering explanation. The walkthrough says the shutters remember the ORDER you flipped the switches in. wUndergroundSwitchPositions is a single byte that switches 1/2/3 add 1/2/3 to, so 1-2-3 and 3-2-1 both end at 6. The observable difference comes from which doors the INTERMEDIATE positions left untouched (position 3 vs position 5 differ on door 5 at (10,10)). The end result the walkthrough describes is correct; the stated reason is not. The derivation above was done by hand from the .PositionN arms - worth re-checking on hardware or an emulator before a bot depends on it.
  3. Party orderings. The walkthrough lists GRUNTF_4 as Ekans/Ekans/Gloom/Oddish and EXECUTIVEF_1 as Arbok/Murkrow/Vileplume. The asm orders are 21 EKANS, 23 ODDISH, 21 EKANS, 24 GLOOM and 32 ARBOK, 32 VILEPLUME, 32 MURKROW. Same mons, different send-out order; a bot that hard-codes lead expectations should use the asm order.
  4. "the northwesternmost building" - resolved to warp_event 9, 5, GOLDENROD_UNDERGROUND_SWITCH_ROOM_ENTRANCES, 8 and the adjacent bg_event 8, 6 GoldenrodCityUndergroundSignNorth, but the walkthrough never names it, so this is an inference from the map geometry rather than a quoted label.
  5. EXP and money figures ("595 EXP", "960G", etc.) were not verified. Money is base money x level from the trainer class table, which was not opened; EXP depends on the player's party. Nothing in this document depends on them.
  6. EVENT_TEAM_ROCKET_DISBANDED is set only on the Gold branch of RadioTower5FRocketBossScript (line 130), not on the Silver branch. Its only other consumers are maps/PewterCity.asm:51 (also setevent) and the TIN_TOWER_1F sage object mask at maps/TinTower1F.asm:56. This looks intentional (Gold gets the Rainbow Wing and therefore Ho-Oh access), but it is an asymmetry a port could easily get wrong, so it is flagged rather than asserted.
  7. verbosegiveitem with no iffalse in FakeDirectorScript (Basement Key) and GoldenrodUndergroundWarehouseDirectorScript (Card Key). If the Key Items pocket were full the scripts would continue as if the item had been given. Gen 2's Key Items pocket is large enough that this is presumably unreachable, but the guard genuinely is not there.
  8. Radio Tower 3F TrainerGruntM9 reacts with "Why did the shutter open?" and his after-battle text mentions the Underground, which confirms he is meant for the post-Card-Key pass; but nothing in the asm prevents reaching (16,6) some other way if the block edit were bypassed. Not verified against the .blk collision data.
