/* Handling the core type is finicky. Based on the arguments we pass in,
* we handle it differently.
* Some current cases which track desired behavior and how it is supposed to work:
*
* Dynamically linked RA:
* ./retroarch -> CORE_TYPE_DUMMY
* ./retroarch -v -> CORE_TYPE_DUMMY + verbose
* ./retroarch --menu -> CORE_TYPE_DUMMY
* ./retroarch --menu -v -> CORE_TYPE_DUMMY + verbose
* ./retroarch -L contentless-core -> CORE_TYPE_PLAIN
* ./retroarch -L content-core -> CORE_TYPE_PLAIN + FAIL (This currently crashes)
* ./retroarch [-L content-core] ROM -> CORE_TYPE_PLAIN
* ./retroarch <-L or ROM> --menu -> FAIL
*
* The heuristic here seems to be that if we use the -L CLI option or
* optind < argc at the end we should set CORE_TYPE_PLAIN.
* To handle --menu, we should ensure that CORE_TYPE_DUMMY is still set
* otherwise, fail early, since the CLI options are non-sensical.
* We could also simply ignore --menu in this case to be more friendly with
* bogus arguments.
