"""Batocera runs every emulator its ES lists, not only each system's default.

The platform scraper read configgen-defaults.yml alone, one core per system,
so DOSBox Staging, melonDS DS and nine other cores Batocera builds and lets a
user pick stayed outside the pack. The target scraper read es_systems.yml but
dropped a standalone emulator's own name, keeping only the machines listed
under it: amiberry, fsuae and vice were never in a target list.
