Pin moves to 2de3bf8 (v8.4.2). roms/aros-ext.bin, roms/aros-rom.bin and whdboot/game-data/whdload_db.json changed upstream and are collected at that revision. The WHDLoad database is matched on the archive SHA1 first and refreshed from the bundled copy when newer. kick02019.AROS and its .ext are names the Recalbox launcher writes, so the profile now documents the kickstart_rom_file settings instead.
The libretro core copies whdboot from the system directory and uses a candidate only when WHDLoad, JST, AmiQuit, boot-data, the game database and the five RTB files are all there (amiberry.cpp:11510-11584). The core zip has none of them, so they are collected.
