- Hidden Items & Itemfinder (fixes#2314):
* Extract BG_EVENT_HIDDEN_ITEM (kind 7) from GBA ROM with proper flag calculation (0x3E8 + id), underfoot flags, and quantities.
* Implement overworld Itemfinder scan logic (7-tile radius, directional response, underfoot detection, SFX 65, and OEM text).
* Wire up Bag Menu Itemfinder dispatch to overworld field runtime.
- Opponent Battle HUD Caught Marker (fixes#2313):
* Add authentic Pokédex caught Poké Ball icon (B_INTERFACE_GFX_BALL_CAUGHT / tile 70) to opponent healthbox.
* Match pokefirered parity in TryAddPokeballIconToHealthbox (wild encounters only, non-tutorial, non-ghost, checked against Dex).
* Ensure status ailment icons (PSN, PAR, SLP, FRZ, BRN) take rendering priority over the caught ball marker.
- Level-Up Learnset & Movepool Assignment (fixes#2315):
* Fix wild and generated Pokémon moveset assignment to assign the 4 most recent level-up moves up to the current level instead of getting stuck on basic moves (e.g. Tackle).
- Easy Chat / Profile Quick Chat:
* Extract full word groups, categories, and dictionary entries from ROM.
* Build Easy Chat interface with group selection, paginated word lists, and alphabetized filtering.
* Fix dialog text overflowing when exiting profile / quick chat prompts.
- Nurse Joy & PC Storage / Map Polishing:
* Implement Nurse Joy healing tray animation flow and audio cues in standard scripts.
* Fix PC storage box header/wallpaper rendering and storage data extraction.
* Correct Sevii Islands / Island 1 map section lookups and region map coordinate handling.
* Fix circular dependency in battle residual handlers (partialTrap).

wire up Crystal PalMap tile attrs (bank 1, flips, BG_PRIO) through map bake,
attr grid, and BG-over-OAM blits instead of the gold/silver grassAtlasFor shortcut.

keyed grass over feet strip via attrmap, drawBgPriorityOver for wAttrmap bit 7.
gold/silver left alone on the old path — all of this gated behind isCrystal().

Crystal boots from a user-supplied ROM, imports a full cache and is playable:
copyright, the Crystal intro movie, the animated title, gender select, Oak,
and out into Johto. 122 of the cart's 169 script specials are implemented.
Import and data
- tools/make_crystal_manifest.py derives the manifest by importing
make_gold_manifest as a library, with three additive keyword seams. Gold and
Silver still regenerate byte-identical, which is the standing requirement for
touching that generator.
- crystal_symbol_deltas.py and crystal_movie_symbols.py carry the symbol delta:
Crystal renames the credits mons, splits the trainer card, Pokegear and
pack-pal blocks by gender, and replaces the intro and title outright.
- Crystal-only manifest keys: engineFlagOrder (162 flags to Gold's 93, so the
badge block sits one higher) and unownCharmap (the main charmap parser stops
at the first newcharmap so the two cannot contaminate each other).
Extractor
- RomExtractorGen2 becomes three-edition. Crystal corrections: PAL_MAP_BANK
0x13, a flat PICS_FIX pic bank, audio bank 0x5e, the mapSongs id-100 hole,
seven NPC trades, a TradeTexts stride of 8, the five Crystal tileset anim
steps with per-row degrade, and the column-major trainer card portraits.
- New: animated front sprites (frames, bitmasks, play and idle scripts), the
Battle Tower roster, Kris assets, Mobile System GB art, and the Crystal
intro and title via src/import/CrystalMovie.lua.
Engine
- GameVersion gains engine(id) and fixes(id). Gold and Silver keep their
original bugs where the bug is not hardware dependent; Crystal gets the fixes
Crystal shipped: Lucky Number boxes 10-14, surfing onto an NPC, and the
Reflect and Light Screen defence overflow.
- Crystal story: Suicune and Eusine, Celebi behind the GS Ball flag, the Ruins
of Alph chambers, Buena, the Move Tutor, the Poke Seer, and the Battle Tower
including the wInBattleTowerBattle badge-boost guard.
- Kris and the gender flag, animated fronts in battle and the summary screen,
and mon caught data.
Verification
- Every extracted asset is pixel-compared against pret's own source PNGs.
- Gold caches are byte-identical before and after, file for file.
- New Crystal suites plus a T2 Gen 2 tier; the full suite passes.
- Replaced `teardownMountedSession` and `flushEditorPackageLoaded` with a unified `SessionLifecycle` approach for managing session transitions and resource cleanup.
- Implemented `SessionLifecycle.endEditorSession` and `SessionLifecycle.endGameSession` to streamline the teardown process for editor and game sessions.
- Introduced `Assets.releaseSession` to handle GPU resource release at session end, ensuring efficient memory management.
- Updated `Game` and `Game2` reset methods to include world and canvas resource releases.
- Enhanced `MapLoader` with a new `releaseAll` method for eager GPU cache cleanup.
- Added tests to verify the new session lifecycle functionality and resource management.
This commit improves the stability and performance of in-process transitions, particularly during editor and game session changes.
further improves and addresses #1662 specifically around android gc pressure.
- Introduced `teardownMountedSession` to handle cleanup of mounted versions, generated data, and mod states during transitions between the editor and launcher.
- Added `flushEditorPackageLoaded` to evict save-editor modules from `package.loaded` dynamically, ensuring a clean state for subsequent sessions.
- Implemented `Game:reset` and `Game2:reset` methods to clear session-specific fields, allowing for a fresh start when returning to the launcher.
- Enhanced `Renderer` and `TileRenderer` to release GPU resources immediately, preventing memory leaks during rapid transitions.
- Updated `MagnetTrainRide` to support OAM priority overlays and manage background rendering with new shader functionality.
This commit improves the stability and performance of the application during in-process transitions, particularly on Android.

fixes#1662#1643#1536 and finishes fixing #1597
The previous drawCellBottom calls fired only for cells containing a
tracked entity. While walking this worked acceptably because the
sprite's sub-pixel tween kept the visual overlap plausible, but while
standing still the sprite is pixel-aligned with the cell and the opaque
leaf-edge pixels in the grass bottom row paint over the player's feet.
This change removes the per-entity isGrassCell checks and replaces them
with a single post-sprite pass that overdraws every visible grass cell.
TileRenderer:
- ensureWindow now builds grassCells (all paths) and grassBatch (DMG/SGB
shader path) alongside winBatch during the existing tile scan loop.
A grassSeen table deduplicates cells so each cx/cy pair is only
recorded once despite having two bottom-row tiles.
- drawGrassOverdraw: DMG/SGB draws the grassBatch under color0KeyShader
in one call; GBC iterates grassCells and calls drawCellBottomRaw per
cell (pre-keyed images can't share a SpriteBatch).
- markGrassOverdrawRedraw: iterates grassCells and calls
markCellBottomRedraw for the post-zone OBP-replay pass (GBC only).
- releaseBatches cleans up grassBatch and grassCells.
OverworldController (flat path):
- Entity loop draws sprites only; grass overdraw fires once after the
loop via drawGrassOverdraw + markGrassOverdrawRedraw.
OverworldController (tilt path):
- Grass cells are injected into the billboard sort queue keyed on the
world-pixel foot of each cell's bottom tile row (cy*16+16), so they
depth-sort correctly against entities at different y positions. Each
grass cell billboards via drawCellBottomRaw inside the upright pass.
Fixes: standing-in-tall-grass feet overdraw (Gen 2 confirmed, Gen 1
improved); NPCs and Pikachu follower in grass benefit automatically.
Parity test: tests/parity_grass_seam.lua 10/10, engine 228/228.
