Description

Now that RETRO_ENVIRONMENT_SET_SUBSYSTEM_INFO is implemented (#202), the stored subsystem info needs to be wired up so multi-content cores (e.g. link-cable games) can actually be loaded.

Missing pieces

  • LoadLibretroGameSpecial() public API wrapping retro_load_game_special
  • Menu UI for subsystem selection and multi-file loading
  • CLI support for passing multiple content files with a subsystem index
  • Drag-and-drop handling for multi-file drops

References

  • #202 — stores subsystemInfo/subsystemCount and exposes GetLibretroSubsystemInfo()
  • retro_load_game_special is already loaded as a symbol in LoadLibretroCore()

Research direction

Start by reading the subsystemInfo/subsystemCount storage and GetLibretroSubsystemInfo() from #202, then inspect the existing LoadLibretroCore() symbol loading for retro_load_game_special. Done means exposing LoadLibretroGameSpecial() and supporting subsystem selection and multi-file loading in the menu, CLI, and drag-and-drop paths.
