********************************
* VERSION: 2.0
********************************
*
* - 2.0: Add support for core options v2 interface
* - 1.3: Move translations to libretro_core_options_intl.h
* - libretro_core_options_intl.h includes BOM and utf-8
* fix for MSVC 2010-2013
* - Added HAVE_NO_LANGEXTRA flag to disable translations
* on platforms/compilers without BOM support
* - 1.2: Use core options v1 interface when
* RETRO_ENVIRONMENT_GET_CORE_OPTIONS_VERSION is >= 1
* (previously required RETRO_ENVIRONMENT_GET_CORE_OPTIONS_VERSION == 1)
* - 1.1: Support generation of core options v0 retro_core_option_value
* arrays containing options with a single value
* - 1.0: First commit
