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.

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.

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_*.

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

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.

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.

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.

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.

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.
