resolve_platform_cores() links platforms to their cores via three strategies: all_libretro, explicit list, system ID fallback. Pack generation always includes core requirements beyond platform baseline. Case-insensitive dedup prevents conflicts on Windows/macOS. Data dir strip_components fixes doubled paths for Dolphin and PPSSPP caches.
