The SBC and RG34XXSP ports hand LÖVE a source *directory*
(`love <dir>`), so `love.filesystem.isFused()` is false there and
`Boot.run` bailed on its first line. The launcher still offered
"Update vX.Y.Z" and "Restart to update", so an update downloaded,
verified, and then was silently ignored forever.
- Boot.canUpdateInPlace() replaces the fused-only gate: a packaged
build updates whether it is fused (AppImage, Flatpak game.love) or
unpacked, and only a dev / source checkout (engine "0.0.0-dev") is
excluded. Fails closed when the host cannot be established.
Prelaunch.updateAllowed now delegates to it, so the boot gate and the
`--update` gate cannot disagree.
- Check.hostPort() reads the release-target marker, with
POKEPORT_HANDHELD as a legacy fallback (the SBC launcher has always
exported it, so packs predating this change still identify
themselves). The marker was read from the environment but never
exported, so a full-package fallback on a handheld resolved to a
desktop AppImage that cannot run there.
- A handheld now fetches its own package ("Download port update",
reusing the worker's cross-platform download_full) instead of
offering a URL it has no browser to open, and reports "Update package
ready" once it is in the save directory for a manual re-extract.
- Launchers export POKEPORT_PORTMASTER / POKEPORT_RG34XXSP.
An in-place update only ever mounts a payload over the running source,
so relaxing the gate is less invasive than the fused path it joins.
A runtime bump still needs a full package, which the minShell gate
already reports as needs_full.
Tests: tests/engine/update_boot_host_gate.lua (new, 10 checks) pins the
gate; update_check_tests.lua pins both port asset names and hostPort().
scripts/test.sh --quick: all tiers passed; scripts/lint.sh: 0 errors.

- Introduced the `POKEPORT_IDLE_AFTER` and `POKEPORT_IDLE_FPS` environment variables to manage presentation rates on static screens, allowing game logic and audio to maintain full speed.
- Updated the vsync handling to keep it enabled across all platforms, including KMSDRM handhelds, to leverage PresentSync for improved cadence and pacing.
- Enhanced FrameCap logic to ensure proper handling of performance caps in handheld environments, preventing unnecessary software pacing when hardware capabilities are sufficient.
- Adjusted documentation to reflect these changes and their impact on power efficiency and performance.
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.
Silver: derived import manifest (tools/make_silver_manifest.py re-resolves
the Gold manifest's symbols from pokesilver.sym), silver GameVersion row,
generation-keyed extractor routing, required-files override, edition save
stamping (a Silver playthrough no longer writes into the Gold save),
checkver-driven edition data, SILVER/KAMON/OSCAR/MAX presets, GOLD rival
default, edition credits banner, Lugia title screen (OAM layouts, bob,
trail, palettes as title.lua data keys with Gold defaults so old caches
need no re-import), packaging for every build target, docs, and tests.
Launcher: the installed-mods list is one continuous scroll (rows culled to
the viewport) instead of a pager with an inner scroll viewport; the pad
cursor's edge-scroll no longer runs it to the bottom. The game dropdown
shows just the initial and caret. Find-tab behavior unchanged.
Title tempo: a sprite-anim frame shows duration+1 ticks
(engine/sprite_anims/core.asm GetSpriteAnimFrame), which locks both
editions' 64-tick wing beat to the 64-tick sine bob; the title screens no
longer run fast and out of phase.
