Notes for the walkthrough's Lavender claims

  • Mr. Fuji is MrFuji, object_event 4, 2, SPRITE_GRAMPS in maps/SoulHouse.asm:85 (warp 6 of Lavender Town), so the walkthrough is right that he is in the Soul House. MR_FUJIS_HOUSE (warp 2, maps/MrFujisHouse.asm) is the Volunteer Pokemon House and contains no Fuji object.
  • Name Rater is warp 4 -> LAVENDER_NAME_RATER (maps/LavenderNameRater.asm).

Wild encounters - none in town.

Note this is a flag, not a bag item - nothing enters the inventory.
  • The upstairs floors are blocked by dialogue only (LavRadioTower1FOfficerScript is flavour text); the map has no warp to 2F.

Two things a bot must know: beating Erika retroactively sets all four minor trainers' beaten flags, so a rematch sweep is impossible after the leader; and the TM is handed out in the same conversation, so a full bag silently skips it and you must talk to her again.

Celadon Gym is NOT Cut-gated in pokegold. maps/CeladonCity.blk contains a single kanto cut-tree block ($60) at block (14,17) = cell (28,34), in the bottom-right of the map, nowhere near the gym. The gym door is the DOOR quadrant of block $12 at block (5,14) = cell (10,29) (data/tilesets/kanto_collision.asm tilecoll WALL, WALL, DOOR, WALL ; 12), and the cell directly below it, block (5,15) = $79 (tilecoll FLOOR, FLOOR, FLOOR, WALL ; 79), is walkable floor. Nothing between the city and the gym requires Cut.

5. Port coverage

The Gen 2 port is data-driven: src/import/RomExtractorGen2.lua reads every map header, def_warp_events / def_coord_events / def_bg_events / def_object_events table and script pointer straight out of the ROM (RomExtractorGen2:readMapEvents, line 782), so per-map coverage is not a per-map Lua file. What follows is coverage of the mechanics this section needs.

Beat Port file Status
Map blocks, collision, warps, connections src/world/gen2/Map.lua, src/world/gen2/Permissions.lua implemented (generic)
Warp / object / bg / coord event extraction src/import/RomExtractorGen2.lua:782 readMapEvents implemented
Script VM (checkevent, setevent, checkflag, setflag, verbosegiveitem, giveitem, takeitem, loadtrainer, startbattle, winlosstext, applymovement, checktime, showemote, variablesprite, gettrainername) src/script/gen2/Opcodes.lua, src/script/gen2/Vm.lua implemented
Item balls (OBJECTTYPE_ITEMBALL) src/world/gen2/Events.lua, src/world/gen2/Npc.lua implemented
Hidden items (BGEVENT_ITEM -> hiddenitem) src/world/gen2/HiddenItems.lua implemented (the header notes World:bgEventAt previously only answered BGEVENT_READ)
Fruit trees (fruittree FRUITTREE_ROUTE_8) src/core/gen2/Apricorns.lua (tryResetFruitTrees, treePicked), VM fruittree branch src/script/gen2/Vm.lua:1191 implemented
Overworld trainers: eyesight, trainer struct, party build src/world/gen2/Trainers.lua implemented
Field moves Cut / Flash / Surf, badge order, CutTreeBlockPointers src/world/gen2/FieldMoves.lua (CUT = "HIVE", FLASH = "ZEPHYR", SURF = "FOG", cutFromMenu, flashFromMenu, surfFromMenu) implemented
Badge storage incl. RAINBOWBADGE src/inventory/Badges.lua:12, src/ui/gen2/TrainerCard.lua:67 implemented
Game Corner prize counters (TM + mon, coin case, party-full check) src/ui/gen2/PrizeMenu.lua, special GameCornerPrizeMonCheckDex in src/script/gen2/Specials.lua:964 implemented
Slot machine (Celadon Game Corner floor) src/ui/gen2/SlotMachine.lua implemented
Magnet Train ride src/core/gen2/MagnetTrain.lua, src/ui/gen2/MagnetTrainRide.lua implemented

special Diploma (mansion 3F) src/ui/gen2/Diploma.lua, src/script/gen2/Specials.lua:1853 implemented; special PrintDiploma is a stub
Headless driver coverage for this stretch tests/drivers/gold_*.lua missing - all 25 gold drivers are Johto-side (gold_walk_smoke.lua runs New Bark -> Route 29); nothing exercises Rock Tunnel, Route 8/7, Celadon, or the Erika fight

6. Unresolved / verify by hand

  1. "Head to the southwest part of town with a Pokemon that can use the HM01 Cut and you'll arrive at Erika's gym." Not supported by the asm. There is exactly one kanto cut-tree block in maps/CeladonCity.blk ($60 at block (14,17) = cell (28,34)) and it is not on the path to the gym. The gym door is block $12 at (5,14), approached from walkable block $79 at (5,15). This looks like a carry-over from Red/Blue. Verify in-game before writing a Cut step into a driver.
  2. Route 7 wild list. The walkthrough gives Pidgeotto / Vulpix / Meowth. data/wild/kanto_grass.asm def_grass_wildmons ROUTE_7 in the IF DEF(_GOLD) branch is Rattata / Spearow / Growlithe / Raticate / Murkrow / Houndour; Meowth and Vulpix only appear in the _SILVER branch, and Pidgeotto appears on Route 8, not Route 7. Treat the FAQ list as Silver-flavoured.
  3. Rock Tunnel item list. The walkthrough lists Iron, PP Up, Revive and TM47 and omits the ELIXER ball at ROCK_TUNNEL_1F (4,18), the hidden X_ACCURACY at 1F (24,4), the hidden X_DEFEND at 1F (21,15) and the hidden MAX_POTION at B1F (4,14).
  4. Erika's held items. The walkthrough says "three Full Restores". data/trainers/attributes.asm:125 gives the Erika class db HYPER_POTION, NO_ITEM. The count of AI item uses is engine behaviour, not a party field; the item is a Hyper Potion, not a Full Restore.
  5. Erika's lead order. parties.asm:331 orders Tangela, Jumpluff, Victreebel, Bellossom; the walkthrough's strategy section is ordered Tangela, Victreebel, Bellossom, Jumpluff.
  6. Bellossom's Synthesis "heals half its health every turn". Synthesis's actual healing fraction is weather-dependent in the move effect (engine/battle/effect_commands.asm); not pinned down here.
  7. "Rail Pass" vs "Magnet Train Pass". The walkthrough describes two separate rewards ("Rail Pass" first, then "Magnet Train Pass"). In the asm there is one item, PASS, given once by Copycat.GivePass; the "rail PASS" wording is just CopycatText_Male_2 / CopycatText_Male_3 flavour.
  8. "The Saffron City guard will check your Pokedex as ID." Route7SaffronGuardScript has no checkitem, no coord event and no blocking movement - it is a two-branch text switch on EVENT_RETURNED_MACHINE_PART. The gate is passable regardless.
  9. "You can play slots in the middle of town" - the slot machines' def_object_events / def_bg_events rows in maps/CeladonGameCorner.asm were not transcribed here (only its two warps); if a bot needs to sit at a specific machine, read that file.
  10. Exact experience and prize-money numbers quoted by the walkthrough (e.g. "1447 EXP", "1120G") were not verified; they are computed at runtime from base stats and data/trainers/attributes.asm base rewards, not stored as table values.
