Section 23 - Routes 11-19 and Fuchsia City Gym

Source: ../section-23-routes-11-19-and-fuchsia-city-gym.txt Maps covered: MAP_ROUTE_12, MAP_ROUTE_11, MAP_ROUTE_12_SUPER_ROD_HOUSE, MAP_ROUTE_13, MAP_ROUTE_14, MAP_ROUTE_15, MAP_ROUTE_15_FUCHSIA_GATE, MAP_FUCHSIA_CITY, MAP_FUCHSIA_POKECENTER_1F, MAP_ROUTE_16, MAP_ROUTE_16_GATE, MAP_ROUTE_16_FUCHSIA_SPEECH_HOUSE, MAP_ROUTE_17, MAP_ROUTE_17_ROUTE_18_GATE, MAP_ROUTE_18, MAP_FUCHSIA_GYM

Badges / key milestones in this section:

  • ENGINE_SOULBADGE (Kanto badge 5) from FuchsiaGymJanineScript in maps/FuchsiaGym.asm
  • EVENT_GOT_TM06_TOXIC -> TM_TOXIC (item id $c5, constants/item_constants.asm:226)
  • EVENT_GOT_SUPER_ROD -> SUPER_ROD from maps/Route12SuperRodHouse.asm
  • ENGINE_FLYPOINT_FUCHSIA armed on first entry to MAP_FUCHSIA_CITY
  • Cycling Road forced-bike state (ENGINE_ALWAYS_ON_BIKE, ENGINE_DOWNHILL)

Despite the section title, the walkthrough text never enters MAP_ROUTE_19 (see "Unresolved").

Cut trees (block-level, not objects)

Scanned maps/Route12.blk against the TILESET_KANTO rows of data/collision/field_move_blocks.asm (CutTreeBlockPointers.kanto), quadrant taken from data/tilesets/kanto_collision.asm:

block (bx, by) block id cut quadrant walk cell to face
(3, 22) $35 top-right (7, 44)
(3, 24) $33 bottom-right (7, 49)

The (7, 44) tree is the one guarding the Calcium ball at (5, 43).

Scripts of interest

  • TrainerFisherKyle / TrainerFisherMartin / TrainerFisherStephen / TrainerFisherBarney - each is a bare trainer FISHER, <NAME>, EVENT_BEAT_*, <seen>, <beaten>, 0, .Script; .Script is endifjustbattled / opentext / writetext <after> / waitbutton / closetext / end. No flags beyond the beat event, no items, no movement.
  • Route12Calcium / Route12Nugget - itemball rows; the object's own event flag is what makes them one-shot.
  • Route12HiddenElixer - hiddenitem ELIXER, EVENT_ROUTE_12_HIDDEN_ELIXER.

All four are TRAINERTYPE_NORMAL (no custom moves/items). FISHER base reward is 10 (data/trainers/attributes.asm:223).

Wild encounters

  • Grass: none. ROUTE_12 has no def_grass_wildmons row in data/wild/kanto_grass.asm.
  • Water (data/wild/kanto_water.asm:33): def_water_wildmons ROUTE_12, 6% rate - L25 Tentacool, L25 Quagsire, L25 Tentacruel (no time split; water tables are single-slot-set).
  • Fishing group FISHGROUP_QWILFISH_NO_SWARM (data/wild/fish.asm:177-193, the .Qwilfish_NoSwarm_* labels alias .Qwilfish_*):
    • Old: Magikarp 10 (70%+1), Magikarp 10 (85%+1), Tentacool 10
    • Good: Magikarp 20 (35%), Tentacool 20 (70%), Tentacool 20 (90%+1), time_group 20 = Tentacool 20 day / Tentacool 20 nite
    • Super: Tentacool 40 (40%), time_group 21 = Tentacool 40, Magikarp 40 (90%+1), Qwilfish 40

Scripts of interest

  • Route11FruitTree - single fruittree FRUITTREE_ROUTE_11. data/items/fruit_trees.asm gives index 24 ($18) = BERRY. Fruit trees are day-tracked, not one-shot events.
  • Route11HiddenRevive - hiddenitem REVIVE, EVENT_ROUTE_11_HIDDEN_REVIVE, faced from cell (32, 5), directly below the fruit tree.
  • The four trainer scripts are the plain endifjustbattled pattern.

Wild encounters

data/wild/kanto_grass.asm:728 def_grass_wildmons ROUTE_11, 10%/10%/10%. Morn, day and nite are the same seven slots: L14 Drowzee, L15 Rattata, L15 Magnemite, L16 Drowzee, L16 Hypno, L16 Hypno, L16 Hypno.

No water table, no def_grass_wildmons time split. The walkthrough's species list omits Magnemite.

Cut trees

maps/Route16.blk block (7, 2) = $32 (CUT_TREE top-right) -> face walk cell (15, 4). This is the tree the walkthrough calls "north of the route-changing building". Cut trees are not persisted: leaving the map (for example into ROUTE_16_FUCHSIA_SPEECH_HOUSE) reloads the block from Route16.blk and the tree is back, which is exactly the behaviour the walkthrough describes.

Scripts of interest

Route16AlwaysOnBikeCallback (4e:5a8f), a MAPCALLBACK_NEWMAP callback:

readvar VAR_YCOORD
ifless 5, .CanWalk
readvar VAR_XCOORD
ifgreater 13, .CanWalk
setflag ENGINE_ALWAYS_ON_BIKE
endcallback
.CanWalk:
clearflag ENGINE_ALWAYS_ON_BIKE
endcallback

So the north-west corner of Route 16 (y < 5, or x > 13) is walkable; the rest of the map forces the bike. Because this is a MAPCALLBACK_NEWMAP, it only re-evaluates on a map load, not while walking.

Flags and events

SCENE_ROUTE16GATE_BICYCLE_CHECK is generated by the scene_script macro (macros/scripts/maps.asm:25, which emits scene_const into a const_def starting at 0), so its value is 0. Nothing anywhere calls setmapscene on this map, so the scene never changes and the coord event fires on every pass.

Note the y-order: Riley (17) -> Joel (32) -> Glenn (53) -> Charles (80). The walkthrough fights Riley, Glenn, Joel, Charles; Joel at (16, 32) is on the right bank (the walkthrough's "bridge across the river to the right") and Glenn at (3, 53) is further down the left, so the asm ordering by y is Riley -> Joel -> Glenn -> Charles.

Scripts of interest

Route17AlwaysOnBikeCallback (4e:5822), a MAPCALLBACK_NEWMAP callback:

setflag ENGINE_ALWAYS_ON_BIKE
setflag ENGINE_DOWNHILL
endcallback

Unconditional for the whole map. ENGINE_DOWNHILL is what engine/overworld/player_movement.asm:13 .GetDPad reads (the bit BIKEFLAGS_DOWNHILL_F, [hl] at line 20): on a downhill map a frame with no d-pad held is rewritten to PAD_DOWN, i.e. the bike coasts south on its own; and player_movement.asm:277-292 downgrades any non-DOWN bike step from STEP_BIKE to STEP_WALK, which is the "uphill is slower" behaviour.

Route17Route18GateBicycleCheck (5e:69ef) is byte-for-byte the same shape as the Route 16 one, with Route17Route18GateCannotPassText.

Important asymmetry for a bot: the shove movement is step RIGHT, so the check only actually blocks the west-to-east direction (walking off Route 17 into the gate at x=5). Coming from Route 18 you enter at x=9 and the coord event at x=5 still fires, but the shove pushes you further right, back the way you came.

Every gym trainer here is OBJECTTYPE_SCRIPT, not OBJECTTYPE_TRAINER - there are no sight lines, so a bot must walk up and press A. The walkthrough's route order matches: Linda (5, 11) -> Cindy (9, 4) -> Barry (4, 2) -> Alice (5, 7) -> Janine (1, 10).

Scripts of interest

LassAliceScript / LassLindaScript / PicnickerCindyScript / CamperBarryScript share one shape:

.BecomesJanine:

end

Script_startbattle (engine/overworld/scripting.asm:1065) copies wBattleResult & ~BATTLERESULT_BITMASK into wScriptVar, so iftrue after startbattle means "did not win". Losing to an impostor leaves its beat-event clear and repaints it as SPRITE_JANINE.

Three bot-critical facts:

  1. There is no iftrue after Janine's startbattle. The badge, the four impostor beat-events and ENGINE_SOULBADGE are set unconditionally on the line after reloadmapafterbattle. Losing to Janine routes through Script_reloadmapafterbattle -> Script_BattleWhiteout (engine/overworld/scripting.asm:1080-1090) and the script never reaches those lines, so the flags are only ever set on a win.
  2. Beating Janine retroactively sets EVENT_BEAT_LASS_ALICE, EVENT_BEAT_LASS_LINDA, EVENT_BEAT_PICNICKER_CINDY and EVENT_BEAT_CAMPER_BARRY, so the four impostors can be skipped entirely.
  3. TM_TOXIC is handed out on a separate checkevent from the badge. If the TM pocket is full the badge is still awarded and the TM is retried the next time you talk to her.

FuchsiaGymStatue - checkflag ENGINE_SOULBADGE / iftrue .Beaten / jumpstd GymStatue1Script, .Beaten does gettrainername STRING_BUFFER_4, JANINE, JANINE1 / jumpstd GymStatue2Script.

Gate Enforced by (file:label) Requirement Unlock condition
Cut trees on Routes 12 (cells (7,44), (7,49)), 13 ((44,4)), 14 ((5,8), (11,14), (3,24)), 16 ((15,4)), Fuchsia ((16,11), (18,19)) engine/events/overworld.asm:117 CutFunction.CheckAble (menu use, 03:47e1) and engine/events/overworld.asm:1741 TryCutOW (walk-into prompt, 03:5193) CheckBadge ENGINE_HIVEBADGE and a party member knowing CUT and CheckMapForSomethingToCut (facing collision COLL_CUT_TREE + block id in CutTreeBlockPointers) Hive Badge, already held long before this section. Cut is not persisted: the block reverts on map reload.

Belongs to a later section; nothing in section 23 clears it.
Safari Zone none - maps/FuchsiaCity.asm warp 7 at (18, 3) is commented ; inaccessible and no script or flag ever opens it n/a never opens in Gold/Silver

Nothing in this section gates on ENGINE_SOULBADGE itself; the badge is the output, not a prerequisite.

  56. Steps 52-55 are optional: step 57 sets all four flags anyway.
  57. MAP_FUCHSIA_GYM, talk to object 2 at (1, 10) (FuchsiaGymJanineScript). Pre: ENGINE_SOULBADGE clear. Post on win: EVENT_BEAT_JANINE, EVENT_BEAT_LASS_ALICE, EVENT_BEAT_LASS_LINDA, EVENT_BEAT_PICNICKER_CINDY, EVENT_BEAT_CAMPER_BARRY, ENGINE_SOULBADGE, then verbosegiveitem TM_TOXIC -> EVENT_GOT_TM06_TOXIC (only if the TM pocket has room; otherwise re-talk).
  58. Exit via warps 1/2 at (4, 17)/(5, 17) -> MAP_FUCHSIA_CITY warp 3.

Prize money for every trainer above is 4 x <class base reward> x <level of the trainer's LAST party mon> (ComputeTrainerReward in engine/battle/read_trainer_party.asm:300 gives base x level, and engine/battle/core.asm:2341 adds that amount four times via the ld c, 4 loop). This reproduces every G figure in the walkthrough exactly.

5. Port coverage

The Gen 2 side of this repo is data-driven: src/import/RomExtractorGen2.lua reads each map's def_warp_events / def_coord_events / def_bg_events / def_object_events tables and the script bytecode straight out of the ROM (readMapEvents, src/import/RomExtractorGen2.lua:787-980), and src/script/gen2/Vm.lua executes the original opcodes. So there is no per-map hand-port to audit for this section; what matters is whether the mechanics each beat needs are implemented.

Prize money x4 loop not located in src/battle/gen2/Prize.lua during this pass unverified - see Unresolved
Any driver that walks this section tests/drivers/gold_*.lua (24 files; none touches Routes 11-19 or Fuchsia) missing

Summary: every mechanic this section needs already exists in the port, but nothing in tests/drivers/ exercises Kanto's south-east loop, the Cycling Road forced-bike state or the Fuchsia Gym impostor script. A gold_cycling_road.lua and a gold_fuchsia_gym.lua driver would be the cheapest way to prove it.

6. Unresolved / verify by hand

  1. Route 19 is never visited. The section is titled "Routes 11-19" but the text stops at Fuchsia City after Route 18. MAP_ROUTE_19 and MAP_ROUTE_19_FUCHSIA_GATE exist (constants/map_constants.asm:178-180, data/maps/attributes.asm:287) and Fuchsia warps 10/11 at (7, 35)/(8, 35) lead there, but no walkthrough beat uses them.
  2. "Cut the tree on your way west" on Route 15. maps/Route15.blk contains none of the five TILESET_KANTO cut-tree block ids. The nearest real cut tree on that path is the Route 14 one at walk cell (3, 24). The Route 15 sentence is most likely a duplicate reference to it.
  3. Janine "Strategy VERSUS Espeon". The walkthrough includes an Espeon strategy paragraph. Janine (1) in data/trainers/parties.asm has no Espeon: the five mons are Crobat, Weezing, Weezing, Ariados, Venomoth. The paragraph appears to be copy-paste residue from another gym.
  4. Party ordering differences. The walkthrough lists several parties in a different order than the ROM. Confirmed divergences: Psychic Herman (asm: Exeggcute, Exeggcute, Exeggutor; guide: Exeggcute, Exeggutor, Exeggcute); Schoolboy Johnny (asm: Bellsprout, Weepinbell, Victreebel; guide: Bellsprout, Victreebel, Weepinbell); PokeFan Carter (asm: Bulbasaur, Charmander, Squirtle; guide: Bulbasaur, Squirtle, Charmander); Bird Keeper Boris (asm: L30 Doduo, L28 Doduo, L32 Dodrio; guide: L30 Doduo, L32 Dodrio, L28 Doduo); Biker Charles (asm: Koffing, Charmeleon, Weezing; guide: Koffing, Weezing, Charmeleon); Lass Linda (asm: Bulbasaur, Ivysaur, Venusaur; guide: Bulbasaur, Venusaur, Ivysaur); Janine (asm order given above). Levels and species sets always match; only the order differs, so lead-mon predictions from the guide are unreliable.
  5. Route 12 items. The walkthrough lists only Calcium and the Super Rod. The map also has a NUGGET itemball at (5, 51) and a hidden ELIXER at (14, 13). Route 13's hidden CALCIUM at (30, 13) and Route 17's hidden MAX_ETHER / MAX_ELIXER are likewise unlisted.
  6. Route 17 fight order. The guide's order (Riley, Glenn, Joel, Charles) does not match the map's y-order (Riley 17, Joel 32, Glenn 53, Charles 80). Since these are OBJECTTYPE_TRAINER objects with sight lines rather than scripted encounters, a bot coasting south will hit them in y-order, not the guide's order.
  7. Prize-money x4 in the port. The disassembly's four-fold payout (engine/battle/core.asm:2341, the ld c, 4 add loop) was not located in src/battle/gen2/Prize.lua during this pass. Worth a direct read before trusting any money-based bot assertion.
  8. Fuchsia City cut trees. Blocks (8, 5) and (9, 9) of maps/FuchsiaCity.blk are $60 cut trees (walk cells (16, 11) and (18, 19)). Neither is mentioned in the walkthrough and neither was traced to a reward; they may simply be scenery on the Safari Zone approach.
  9. Fuchsia warp 7 walkability. maps/FuchsiaCity.asm:135 marks the Safari Zone gate warp ; inaccessible in a comment; the block data behind (18, 3) was not decoded to confirm the tile is impassable. The walkthrough's "even the door is gone" matches the comment, but the collision itself is unverified.
