Section 07 - Burned Tower and Ecruteak City Gym

Source: ../section-07-burned-tower-and-ecruteak-city-gym.txt Maps covered: ROUTE_37, ECRUTEAK_CITY, ECRUTEAK_POKECENTER_1F, DANCE_THEATER, ECRUTEAK_ITEMFINDER_HOUSE, BILLS_FAMILYS_HOUSE, BURNED_TOWER_1F, BURNED_TOWER_B1F, ECRUTEAK_GYM (plus one line on ECRUTEAK_TIN_TOWER_ENTRANCE, which this section only unlocks). Badges / key milestones in this section: FOGBADGE (ENGINE_FOGBADGE), HM03 SURF, ITEMFINDER, EEVEE, TM30 SHADOW BALL, TIME CAPSULE (ENGINE_TIME_CAPSULE), Ecruteak fly point, the three roaming beasts (EVENT_RELEASED_THE_BEASTS).

Note on naming: pokegold's map_const rows carry no MAP_ prefix, so the constants below are written exactly as constants/map_constants.asm spells them.

Note on coordinates: every table below is transcribed verbatim from the map asm. warp_event / coord_event / bg_event / object_event all take x, y as their first two arguments (see the macro comments in macros/scripts/maps.asm), even though the macros emit y first. Coordinates are 16x16 walk cells, origin top-left, so a map_const W, H map spans x = 0 .. 2W-1, y = 0 .. 2H-1.

1. Route order

# Map constant asm file Enter via Leaves via Why (walkthrough beat)
0 VIOLET_CITY maps/VioletCity.asm (carried in from section 06) south to ROUTE_36 Heal after Sudowoodo; swap Togepi for Sudowoodo. Belongs to section 06.
1 ROUTE_36 maps/Route36.asm west from Violet City north connection to ROUTE_37 Pass-through only in this section; Route 36's own items/trainers are section 06's.
2 ROUTE_37 maps/Route37.asm south connection from ROUTE_36 north connection to ECRUTEAK_CITY Twins Ann & Anne, Psychic Greg, three apricorn trees, Sunny (Sundays).
3 ECRUTEAK_CITY maps/EcruteakCity.asm south connection from ROUTE_37 warp 6 (Pokecenter) First arrival; sets ENGINE_FLYPOINT_ECRUTEAK.
4 ECRUTEAK_POKECENTER_1F maps/EcruteakPokecenter1F.asm Ecruteak warp 6 at (23,27) same warp Bill cutscene, Time Capsule, heal, deposit apricorns/berries.
5 ROUTE_37 -> ROUTE_36 -> NATIONAL_PARK -> ROUTE_35 -> GOLDENROD_CITY - biking back south - Backtrack for the apricorn trees and Bill's Eevee. Only Route 37 is owned here.
6 BILLS_FAMILYS_HOUSE maps/BillsFamilysHouse.asm Goldenrod warp 4 at (5,25) same warp givepoke EEVEE, 20.
7 ECRUTEAK_CITY maps/EcruteakCity.asm back north via Route 35/36/37 warp 8 (Dance Theater) Return with Eevee.
8 DANCE_THEATER maps/DanceTheater.asm Ecruteak warp 8 at (23,21) warps 1/2 at (5,13)/(6,13) Five Kimono Girls, then HM03 SURF from the gentleman.
9 ECRUTEAK_ITEMFINDER_HOUSE maps/EcruteakItemfinderHouse.asm Ecruteak warp 11 at (13,27) warps 1/2 at (3,7)/(4,7) ITEMFINDER for answering yesorno with YES.
10 BURNED_TOWER_1F maps/BurnedTower1F.asm Ecruteak warp 13 at (5,5) warps 1/2 at (9,15)/(10,15) Rival battle on entry; Rock Smash gates; drop to B1F.
11 BURNED_TOWER_B1F maps/BurnedTowerB1F.asm fall through a 1F pit ladder at (7,15) HP UP, TM ENDURE, and the ReleaseTheBeasts coord event.
12 ECRUTEAK_GYM maps/EcruteakGym.asm Ecruteak warp 10 at (6,27) warps 1/2 at (4,17)/(5,17) Four ghost trainers on the invisible floor, then Morty.

Spill into the next section: after FOGBADGE the walkthrough points at Olivine Lighthouse and at Union Cave for Lapras. EcruteakGymMortyScript also does setmapscene ECRUTEAK_TIN_TOWER_ENTRANCE, SCENE_ECRUTEAKTINTOWERENTRANCE_NOOP, which is what un-blocks Tin Tower - that map is the next section's problem.

2. Maps

ROUTE_37

  • Script: maps/Route37.asm
  • Blocks: maps/Route37.blk
  • Header: data/maps/maps.asm:250 -> TILESET_JOHTO, ROUTE, LANDMARK_ROUTE_37, MUSIC_ROUTE_36, phone FALSE, PALETTE_AUTO, FISHGROUP_SHORE

  • Connections: data/maps/attributes.asm:211 -> north EcruteakCity (offset -5), south Route36 (offset -10). No east/west.

ROUTE37_FRUIT_TREE3 SPRITE_FRUIT_TREE 15 7 STILL OBJECTTYPE_SCRIPT Route37FruitTree3 -1

The two twin objects really are declared SPRITE_WEIRD_TREE with object consts named ROUTE37_WEIRD_TREE1/2; engine/events/std_scripts.asm carries variablesprite SPRITE_WEIRD_TREE, SPRITE_SUDOWOODO, so the sprite slot is shared with Sudowoodo. Flagged under section 6 as well - see "Unresolved".

Scripts of interest

  • Route37SunnyCallback (MAPCALLBACK_OBJECTS): readvar VAR_WEEKDAY, ifequal SUNDAY -> appear ROUTE37_SUNNY, otherwise disappear ROUTE37_SUNNY. This is the only reason Sunny exists on the map, so a bot must fake or wait for Sunday.
  • SunnyScript (4c:404d): checkevent EVENT_GOT_MAGNET_FROM_SUNNY -> already done; else readvar VAR_WEEKDAY, ifnotequal SUNDAY -> refusal text; else setevent EVENT_MET_SUNNY_OF_SUNDAY, verbosegiveitem MAGNET, setevent EVENT_GOT_MAGNET_FROM_SUNNY.
  • TrainerTwinsAnnandanne1 / TrainerTwinsAnnandanne2: both use the same EVENT_BEAT_TWINS_ANN_AND_ANNE flag, so beating either twin marks both beaten and the second never battles. EVENT_BEAT_TWINS_ANN_AND_ANNE2 exists in constants/event_flags.asm:610 but nothing on this map references it.
  • Route37FruitTree1/2/3 -> fruittree FRUITTREE_ROUTE_37_1/2/3. data/items/fruit_trees.asm:20-22 gives RED_APRICORN, BLU_APRICORN, BLK_APRICORN in that order.

Wild encounters

Grass: none (data/wild/johto_grass.asm has no ECRUTEAK_CITY entry). Water: data/wild/johto_water.asm:246 -> def_water_wildmons ECRUTEAK_CITY, 2% encounter rate, L20 POLIWAG / L15 POLIWAG / L20 POLIWHIRL. Reachable only after SURF is usable, i.e. after Morty. Fishing group FISHGROUP_POND (data/maps/maps.asm:173), see data/wild/fish.asm. Headbutt: data/wild/treemon_maps.asm:35 -> TREEMON_SET_CITY.

ECRUTEAK_POKECENTER_1F

Scripts of interest

  • Scene table: scene_script EcruteakPokecenter1FMeetBillScene, SCENE_ECRUTEAKPOKECENTER1F_MEET_BILL (scene id 0, the wram default) then ..._NOOP (scene id 1). Scene constants are generated positionally by the def_scene_scripts / scene_script macros in macros/scripts/maps.asm:12-33; there is no SCENE_* constants file.
  • EcruteakPokecenter1FMeetBillScene -> sdefer EcruteakPokcenter1FBillActivatesTimeCapsuleScript (52:4299). This is the "you cannot move for a second" the walkthrough describes: it fires on map load, not on a coord trip-wire.
  • EcruteakPokcenter1FBillActivatesTimeCapsuleScript: appear ECRUTEAKPOKECENTER1F_BILL -> applymovement BILL (UP x4, RIGHT x3, turn_head UP) and applymovement PLAYER (UP x3) -> two text blocks -> applymovement BILL (RIGHT, DOWN x4) -> disappear -> clearevent EVENT_MET_BILL -> setflag ENGINE_TIME_CAPSULE -> setscene SCENE_ECRUTEAKPOKECENTER1F_NOOP.

EVENT_MET_BILL is set by the new-game initialisation block in engine/events/std_scripts.asm (the long setevent run around line 514), so Bill's object in BILLS_FAMILYS_HOUSE is masked until this cutscene clears it. Talking to Bill in Goldenrod is impossible before this scene runs - this is the hard ordering constraint behind the walkthrough's backtrack.

Flags and events

constant defined in read/written by meaning for a bot
EVENT_ECRUTEAK_POKE_CENTER_BILL constants/event_flags.asm:1205 appear/disappear in the cutscene Set = Bill hidden here. Set at new game.

BILLS_FAMILYS_HOUSE

Not an Ecruteak map - it is in Goldenrod, warp 4 of GOLDENROD_CITY at (5,25). Included because this section's Eevee comes from here and is ordering-locked by the Ecruteak Pokecenter cutscene.

  • Script: maps/BillsFamilysHouse.asm
  • Header: data/maps/maps.asm:273 -> TILESET_HOUSE, INDOOR, LANDMARK_GOLDENROD_CITY, MUSIC_GOLDENROD_CITY, phone FALSE, PALETTE_DAY
  • Dimensions: constants/map_constants.asm:251 -> map_const BILLS_FAMILYS_HOUSE, 4, 4

Do not confuse with maps/BillsHouse.asm (BILLS_HOUSE, Kanto Route 25, constants/map_constants.asm:197) - that is Bill's grandfather and the stone-for-showing-a-mon chain, nothing to do with Eevee.

It is harmless (each ball still disappears exactly once) but a bot reading flags to decide "do I already have the Burn Heal" must use the row's flag, not the item name.

The two SPRITE_GROWLITHE triples are the same three beasts drawn twice: the ..._1 set (SPRITEMOVEDATA_POKEMON, coloured PAL_NPC_BROWN/RED/BLUE) is the animated set, the ..._2 set (STANDING_DOWN, PAL_NPC_EMOTE) is the static set. EVENT_BURNED_TOWER_B1F_BEASTS_1 is set by the new-game init block in engine/events/std_scripts.asm:525, so the static set is what you first see; ReleaseTheBeasts does appear/disappear to swap them.

Movement note: B1F is built on HOP_* ledge tiles (data/tilesets/cave_collision.asm). Landing anchors (17,7) and (10,8) are themselves ledge tiles; walking off a ledge tile in the ledge's direction becomes a two-cell jump (.TryJump / .ledge_table, engine/overworld/player_movement.asm:350-392). The route to the beasts is: fall through 1F's centre pit at (10,7) -> land at B1F (10,8) -> walk UP to (10,7), (10,6) -> LEFT to (9,6) -> UP onto (9,5) -> ReleaseTheBeasts.

Every hole (warps 4-33) dumps you at warp 3, i.e. (4,14), just inside the door - the walkthrough's "fall off the path anywhere and it'll drop you back to the gym entrance". Warp 3's own destination (warp 4 at (2,4)) is never used, because (4,14) is a FLOOR tile and CheckWarpCollision only fires on pit/warp collisions.

(rows 15-17 above are schematic for the statue/door area; the pit rows 4-13 are exact.)

Two data quirks, both verified by diffing the warp rows against the block collision:

  • (6,7) has a warp row but is a FLOOR tile, so it never triggers. This is what makes the walkthrough's "go right 3" step from (3,7) land safely on (6,7).
  • (6,4) is a PIT tile with no warp row at all. CheckWarpCollision sets carry, GetDestinationWarpNumber finds no match, CheckWarpTile returns no carry, so you simply stand on it. This is what makes "move up two squares to get past the platform" work. It looks like the (6,4) row was mistyped as (6,7).

The verified zig-zag path (every cell below is FLOOR unless noted):

4. Bot checklist

Preconditions carried in from section 06: Sudowoodo beaten/caught, bicycle owned (EVENT_GOT_BICYCLE), ENGINE_BIKE_SHOP_CALL_ENABLED set.

  1. ROUTE_37, walk from the ROUTE_36 south connection. Optional: fight TrainerTwinsAnnandanne1 at (6,12) (sight 1) - pre EVENT_BEAT_TWINS_ANN_AND_ANNE clear, post set (this also disables the twin at (7,12)).
  2. ROUTE_37 (9,6): fight TrainerPsychicGreg (sight 3). Post EVENT_BEAT_PSYCHIC_GREG.
  3. ROUTE_37: talk to the fruit trees at (13,5), (16,5), (15,7) -> RED / BLU / BLK apricorn. Precondition: bag space. No flag; resets daily.
  4. ROUTE_37 (4,2): ITEMFINDER-less hidden ETHER, flag EVENT_ROUTE_37_HIDDEN_ETHER.
  5. Optional, Sundays only: ROUTE_37 (16,8) talk SunnyScript -> MAGNET. Precondition VAR_WEEKDAY == SUNDAY; post EVENT_GOT_MAGNET_FROM_SUNNY.
  6. Walk north into ECRUTEAK_CITY. Postcondition ENGINE_FLYPOINT_ECRUTEAK set by EcruteakCityFlypointCallback (MAPCALLBACK_NEWMAP).
  7. ECRUTEAK_CITY warp 6 at (23,27) -> ECRUTEAK_POKECENTER_1F. On map load the scene script fires (scene 0). Do not press anything for the length of the cutscene. Post: EVENT_MET_BILL cleared, ENGINE_TIME_CAPSULE set, scene -> 1. Then heal at the nurse (3,1) and deposit apricorns/berries at the PC.
  8. Ride back south: ROUTE_37 -> ROUTE_36 -> NATIONAL_PARK -> ROUTE_35 -> GOLDENROD_CITY. Somewhere in here the bike-shop call fires (DoBikeStep, 1024 bike steps).
  9. GOLDENROD_CITY warp 4 at (5,25) -> BILLS_FAMILYS_HOUSE. Precondition: party count < 6. Talk to Bill at (2,3), answer YES. Post EVENT_GOT_EEVEE, L20 EEVEE in party.
  10. Optional: talk to the twin at (5,4) to register PHONE_BILL.
  11. Ride back north to ECRUTEAK_CITY.
  12. ECRUTEAK_CITY warp 8 at (23,21) -> DANCE_THEATER.
  13. In DANCE_THEATER, walk adjacent and press A on each Kimono Girl - they all have sight 0 and will not start a battle themselves: (0,2) NAOKO / FLAREON, (2,1) SAYO / ESPEON, (6,2) ZUKI / UMBREON, (9,1) KUNI / VAPOREON, (11,2) MIKI / JOLTEON. Each posts its own EVENT_BEAT_KIMONO_GIRL_*.
  14. DANCE_THEATER (7,10): talk to the gentleman. Precondition: all five flags set and bag space for an HM. Post EVENT_GOT_HM03_SURF + HM_SURF in bag. Teach SURF now; it will not work in the field until step 24.
  15. Leave via warp 1/2 at (5,13)/(6,13).
  16. ECRUTEAK_CITY warp 11 at (13,27) -> ECRUTEAK_ITEMFINDER_HOUSE. Talk to (2,3), answer YES to the yesorno. Post EVENT_GOT_ITEMFINDER.
  17. Optional: with ITEMFINDER, pick up the hidden HYPER_POTION at ECRUTEAK_CITY (23,14).
  18. Heal, stock Escape Ropes / Repels / Great Balls, then ECRUTEAK_CITY warp 13 at (5,5) -> BURNED_TOWER_1F.
  19. On entry the rival scene fires immediately (scene 0 -> sdefer BurnedTower1FRivalBattleScript). Precondition: EVENT_RIVAL_BURNED_TOWER clear (i.e. the Goldenrod Underground rival fight has not happened). Battle is RIVAL1 / RIVAL1_3_{CHIKORITA|CYNDAQUIL|TOTODILE} chosen from EVENT_GOT_TOTODILE_FROM_ELM / EVENT_GOT_CHIKORITA_FROM_ELM. Post: rival disappears, scene -> SCENE_BURNEDTOWER1F_FIREBREATHER_DICK.
  20. BURNED_TOWER_1F: walk (9,15) -> (9,14) -> row 13 west to (2,13), north up column 2/3 to the (4,3) rock. Use ROCK_SMASH on it (field move or AskRockSmashScript yes-prompt). This opens the whole north half.
  21. Step on the (8,1) tile to trigger FirebreatherDickFight (FIREBREATHER/DICK, L17 CHARMELEON). Post EVENT_BEAT_FIREBREATHER_DICK, scene -> SCENE_BURNEDTOWER1F_NOOP.
  22. Pick up X_SPEED at (7,5) and the hidden ETHER at (8,7). Then step onto the pit at (10,7) -> BURNED_TOWER_B1F warp 3 at (10,8).
  23. BURNED_TOWER_B1F: walk UP to (10,7), (10,6), LEFT to (9,6), UP to (9,5). Precondition scene 0. This runs ReleaseTheBeasts. Post EVENT_RELEASED_THE_BEASTS, scene -> 1, special InitRoamMons seeds the three roamers.
  24. Optional B1F loot: NUGGET hidden at (8,3). Then leave by the ladder at (7,15) (the only exit).
  25. Optional, back on 1F: smash the (16,13) rock to open the east loop - FIREBREATHER/NED at (16,8) and the BURN_HEAL ball at (15,2).
  26. Optional HP UP: from 1F step on any of the NW pits (5,4), (5,5), (5,6), (4,6) -> B1F (3,3), grab HP_UP at (4,3), hop the ledges south and out via the (7,15) ladder.
  27. Leave BURNED_TOWER_1F via warp 1/2 at (9,15)/(10,15). Heal at the Pokecenter, save.
  28. ECRUTEAK_CITY warp 10 at (6,27) -> ECRUTEAK_GYM. Walk the exact path in the ECRUTEAK_GYM section above. Fight, in order: SAGE/PING at (3,13), MEDIUM/GRACE at (7,9), SAGE/JEFFREY at (2,7), MEDIUM/MARTHA at (7,5).
  29. Talk to Morty at (5,1) from (5,2). Battle MORTY/MORTY1. Post EVENT_BEAT_MORTY, ENGINE_FOGBADGE set, setmapscene ECRUTEAK_TIN_TOWER_ENTRANCE, ...NOOP.
  30. Keep talking to Morty (same script, .FightDone arm) with bag space to get TM_SHADOW_BALL. Post EVENT_GOT_TM30_SHADOW_BALL. If the bag was full the flag is not set and the give can be retried.
  31. Field SURF is now legal (TrySurfOW CheckEngineFlag ENGINE_FOGBADGE passes). The Ecruteak water encounter table (ECRUTEAK_CITY, 2%, POLIWAG / POLIWHIRL) becomes reachable.

6. Unresolved / verify by hand

  1. "Head left and all the way around the spiral and you will now fight your rival." The asm disagrees. BurnedTower1FRivalBattleScene is scene 0 (the wram default) and sdefers the battle script, so it runs on map load; the rival object sits at (9,12), three cells straight up from the (9,15) door, and walks two steps DOWN to meet you. The battle happens as soon as you step inside.
  2. "Equipping the TM Rock Smash will give you the HP Up at the northeastern part of the floor." Conflated. The northeast item on 1F is a BURN_HEAL ball at (15,2) behind the (16,13) rock. The HP_UP is on B1F at (4,3), reached by falling through the northwest pits - which the walkthrough gets right later ("grab a HP Up by dropping down the northwest hole").
  3. Rock Smash is not optional if you want the beasts. Flood-filling maps/BurnedTower1F.blk against data/tilesets/tower_collision.asm from the (9,15) door shows that with both rocks intact you can only reach the four northwest pits, the ladder, and the (4,14)/(5,14)/(14,14)/(15,14) pits - not the centre pit at (10,7), which is the only route to B1F's (9,5) beast trigger. This is a derived result, not a line of asm; worth confirming on hardware/emulator before a bot depends on it.
  4. Ecruteak Gym (6,7) carries a warp_event row but its block collision is FLOOR, so the warp never fires. (6,4) is the mirror image: a PIT tile with no warp_event row, so you can stand on it. Both are consistent with the walkthrough's step counts working, and both look like one transposed row in the source data. Derived from the .blk; verify visually.
  5. Morty's party order. The walkthrough lists "L21 Gastly, L23 Haunter, L25 Gengar, L23 Haunter". MortyGroup in data/trainers/parties.asm:35 is L21 GASTLY, L21 HAUNTER, L25 GENGAR, L23 HAUNTER. The second Haunter is level 21, and its EXP figure in the walkthrough (567) is therefore suspect.
  6. DanceTheaterSurfGuy.GetSurf has no iffalse after verbosegiveitem HM_SURF. Every other give in this section (ITEMFINDER, TM_SHADOW_BALL, the Bill's-grandpa stones) checks the return. If the bag genuinely cannot take an HM the flag would still be set. Whether the bag can ever be full for the HM pocket in GS is worth checking before a bot risks it - keep at least one free slot.
  7. Twins Ann & Anne share one flag. Both objects use EVENT_BEAT_TWINS_ANN_AND_ANNE; EVENT_BEAT_TWINS_ANN_AND_ANNE2 (constants/event_flags.asm:610) is defined but unreferenced by this map. A bot that expects two battles on Route 37 will hang.
  8. Route 37's twins are declared SPRITE_WEIRD_TREE with object consts ROUTE37_WEIRD_TREE1/2, and SPRITE_WEIRD_TREE is variablesprited to SPRITE_SUDOWOODO by the new-game init block. Transcribed verbatim from maps/Route37.asm:237-238; what actually renders on screen was not verified.
  9. Burned Tower 1F item ball flags are crossed (BURN_HEAL ball carries EVENT_BURNED_TOWER_1F_X_SPEED and vice versa). Verbatim from maps/BurnedTower1F.asm:311-312. Functionally harmless, but do not infer the item from the flag name.
  10. Ledge (HOP_*) traversal on B1F could not be found in the port. The asm side is engine/overworld/player_movement.asm:350-392 (.TryJump / .ledge_table, a two-cell jump when leaving a ledge tile in its direction). Marked "unverified" in the port table above.
  11. EcruteakGymActivateRockets branches on VAR_BADGES == 6 / == 7. On a linear run Fog is the fourth badge so neither arm fires; a badge-skipping bot will trigger GoldenrodRocketsScript / RadioTowerRocketsScript out of order. Not exercised in this section.
  12. Walkthrough EXP and money figures were not checked against engine/battle/ at all; they are reproduced nowhere in this document for that reason.
