DualDex 1.1.0-rc.9

RC9 corrects Atlas location identity and makes the local-map switch available for structurally decoded maps that do not have wild encounters.

Atlas and local maps

Complete, structurally valid Gen III gMapGroups catalogs are retained instead of reducing them to encounter-bearing maps. Sparse hacks keep the existing encounter-keyed fail-closed fallback.
Modern Emerald v3.5 now reconstructs 557/557 local maps. Its live map 0x0009 resolves as Littleroot Town with an exact 320×320 ROM-derived raster.
Gen III local rendering supports all 16 hardware-addressable BG palette banks. This covers tiles that use dynamically loaded upper palette slots without weakening tileset or raster validation.
Atlas no longer substitutes the first revealed marker when the live location is unavailable, eliminating the appearance that the player occupies two places.
The Local/Atlas shortcut appears whenever the current decoded map has a local asset. Area Pokédex remains disabled for locations without encounters.

Atlas header actions now place Area Pokédex before Settings, matching the Pokédex view.
The welcome screen now says Choose a Pokémon game to begin. and removes implementation-oriented storage commentary.

Catalog schema revision advances from 14 to 15. RC8-derived catalogs rebuild once; settings, discovery knowledge, and SaveRAM snapshots remain intact.

Official Ruby, Sapphire, Emerald, FireRed, LeafGreen, and Modern Emerald v3.5 retained exact Atlas and complete local-map catalogs: 394/394/518/425/425/557 maps.
Modern Emerald v3.5 retained its exact Atlas raster and resolves live base 0x0009 as Littleroot Town with the frozen local-map raster hash.
The 557-map catalog survived SQLite write/reopen and the Littleroot local PNG was served byte-for-byte by the production loopback API.
Sparse Gen III map-group and Atlas resolver controls remained green.
