Two Birth Island visuals were missing against pokefirered.
The rock never reddened as the puzzle progressed. pret loads
sDeoxysObjectPals[num] into the rock's OBJ palette (field_specials.c:2398);
the engine can only substitute colours into the already-baked sprite, and the
ramp it matched against held the .pal ASCII values (32/82/139) while the ROM
bakes 33/82/140, so almost every pixel missed the lookup. ROCK_PALS now holds
the 8-bit expansion of the ROM ramp at 0x3F6206 (verified byte-exact against
all 11 palettes), sourcePalette() supplies the pristine colours the meteorite
is baked with, and recolour_sprite falls back to the nearest source colour
within a small tolerance so a one-unit rounding difference can never silently
kill the swap again. A swap that matches nothing now returns nil and says so.
The rock vanished instead of shattering. FLDEFF_DESTROY_DEOXYS_ROCK already
ran the camera shake and thunder, but the fragment stage had no artwork and
moved the shards wrongly. Added the four 8x8 tiles from ROM 0x3CBDB0 with
palette 0x3F6346 (ramp step 10, the awakened red pret inherits from the rock);
decoding them through the field-effect extractor reproduces the original
graphics exactly, so no nibble handling was needed. The shards now all spawn
at the rock's own corner and travel +/-16 x / +/-12 y per frame with no
gravity (field_effect.c:3993), dropping out once they leave the viewport, while
the shake decays from amplitude 4 and the rock is removed.
Cache version 111 forces existing caches to re-import so the new sheet appears.

Ports pokefirered's Birth Island Deoxys puzzle and its battle in full.
Puzzle (src/core/game3/deoxys.lua), from src/field_specials.c:2319-2456:
- Task_DoDeoxysTriangleInteraction with the 11 rock positions, the 10
per-step caps and the pre-reset step-counter read that pret uses.
- IncrementBirthIslandRockStepCount wired into StepEvents.onStepTaken.
- MoveDeoxysObject / SetDeoxysTrianglePalette palette swaps, realised via
a new OwSprites.setObjectPalette colour substitution because palettes
are baked to RGBA at extract time.
- FLDEFF_MOVE_DEOXYS_ROCK (67) and FLDEFF_DESTROY_DEOXYS_ROCK (68), plus
setfieldeffectargument plumbing and the rock-move lerp / rock-shatter
field effects.
- DoDeoxysTriangleInteraction = 0x1AB added to Std.SPECIAL, with real
handlers for it and SetDeoxysTrianglePalette.
Battle: seteventmon SPECIES_DEOXYS, 30 expands to CreateEnemyEventMon,
which the engine already implements, so the encounter flows through
Encounters._pendingWild into StartLegendaryBattle. No new code needed
there; tests now pin the whole chain.
Fixes the Deoxys battle theme. Both battle-BGM sites gated on species
386, but FRLG's SPECIES_DEOXYS is 410 (species.h:419) and 386 is
SPECIES_VOLBEAT (species.h:395), so Deoxys silently fell through to the
generic wild theme. Extracted Audio.legendaryBattleSong as the single
source of truth, keyed by the FRLG internal species id, matching the
switch in src/battle_setup.c:349.
Verification: 24/24 Deoxys groups, game3_special_events_test,
engine tier 593/593, luacheck 0/0 in 970 files, plus the hand-run
game3 battle/field-effect/object/step suites.
