#define RETRO_ENVIRONMENT_SET_CONTENT_INFO_OVERRIDE 65
/* const struct retro_system_content_info_override * --
* Allows an implementation to override 'global' content
* info parameters reported by retro_get_system_info().
* Overrides also affect subsystem content info parameters
* set via RETRO_ENVIRONMENT_SET_SUBSYSTEM_INFO.
* This function must be called inside retro_set_environment().
* If callback returns false, content info overrides
* are unsupported by the frontend, and will be ignored.
* If callback returns true, extended game info may be
* retrieved by calling RETRO_ENVIRONMENT_GET_GAME_INFO_EXT
* in retro_load_game() or retro_load_game_special().
*
* 'data' points to an array of retro_system_content_info_override
* structs terminated by a { NULL, false, false } element.
* If 'data' is NULL, no changes will be made to the frontend;
* a core may therefore pass NULL in order to test whether
* the RETRO_ENVIRONMENT_SET_CONTENT_INFO_OVERRIDE and
* RETRO_ENVIRONMENT_GET_GAME_INFO_EXT callbacks are supported
* by the frontend.
*
* For struct member descriptions, see the definition of
* struct retro_system_content_info_override.
*
* Example:
*
* - struct retro_system_info:
* {
* "My Core", // library_name
* "v1.0", // library_version
* "m3u|md|cue|iso|chd|sms|gg|sg", // valid_extensions
* true, // need_fullpath
* false // block_extract
* }
*
* - Array of struct retro_system_content_info_override:
* {
* {
* "md|sms|gg", // extensions
* false, // need_fullpath
* true // persistent_data
* },
* {
* "sg", // extensions
* false, // need_fullpath
* false // persistent_data
* },
* { NULL, false, false }
* }
*
* Result:
* - Files of type m3u, cue, iso, chd will not be
* loaded by the frontend. Frontend will pass a
* valid path to the core, and core will handle
* loading internally
* - Files of type md, sms, gg will be loaded by
* the frontend. A valid memory buffer will be
* passed to the core. This memory buffer will
* remain valid until retro_deinit() returns
* - Files of type sg will be loaded by the frontend.
* A valid memory buffer will be passed to the core.
* This memory buffer will remain valid until
* retro_load_game() (or retro_load_game_special())
* returns
*
* NOTE: If an extension is listed multiple times in
* an array of retro_system_content_info_override
* structs, only the first instance will be registered

* Afterwards it may be called again for the core to communicate
* updated options to the frontend, but the number of core
* options must not change from the number in the initial call.
* If RETRO_ENVIRONMENT_GET_CORE_OPTIONS_VERSION returns an API
* version of >= 2, this callback is guaranteed to succeed
* (i.e. callback return value does not indicate success)
* If callback returns true, frontend has core option category
* support.
* If callback returns false, frontend does not have core option
* category support.
*
* 'data' points to a retro_core_options_v2 struct, containing
* of two pointers:
* - retro_core_options_v2::categories is an array of
* retro_core_option_v2_category structs terminated by a
* { NULL, NULL, NULL } element. If retro_core_options_v2::categories
* is NULL, all core options will have no category and will be shown
* at the top level of the frontend core option interface. If frontend
* does not have core option category support, categories array will
* be ignored.
* - retro_core_options_v2::definitions is an array of
* retro_core_option_v2_definition structs terminated by a
* { NULL, NULL, NULL, NULL, NULL, NULL, {{0}}, NULL }
* element.
*
* >> retro_core_option_v2_category notes:
*
* - retro_core_option_v2_category::key should contain string
* that uniquely identifies the core option category. Valid
* key characters are [a-z, A-Z, 0-9, _, -]
* Namespace collisions with other implementations' category
* keys are permitted.
* - retro_core_option_v2_category::desc should contain a human
* readable description of the category key.
* - retro_core_option_v2_category::info should contain any
* additional human readable information text that a typical
* user may need to understand the nature of the core option
* category.
*
* Example entry:
* {
* "advanced_settings",
* "Advanced",
* "Options affecting low-level emulation performance and accuracy."
* }
*
* >> retro_core_option_v2_definition notes:
*
* - retro_core_option_v2_definition::key should be namespaced to not
* collide with other implementations' keys. e.g. A core called
* 'foo' should use keys named as 'foo_option'. Valid key characters
* are [a-z, A-Z, 0-9, _, -].
* - retro_core_option_v2_definition::desc should contain a human readable
* description of the key. Will be used when the frontend does not
* have core option category support. Examples: "Aspect Ratio" or
* "Video > Aspect Ratio".
* - retro_core_option_v2_definition::desc_categorized should contain a
* human readable description of the key, which will be used when
* frontend has core option category support. Example: "Aspect Ratio",
* where associated retro_core_option_v2_category::desc is "Video".
* If empty or NULL, the string specified by
* retro_core_option_v2_definition::desc will be used instead.
* retro_core_option_v2_definition::desc_categorized will be ignored
* if retro_core_option_v2_definition::category_key is empty or NULL.
* - retro_core_option_v2_definition::info should contain any additional
* human readable information text that a typical user may need to
* understand the functionality of the option.
* - retro_core_option_v2_definition::info_categorized should contain
* any additional human readable information text that a typical user
* may need to understand the functionality of the option, and will be
* used when frontend has core option category support. This is provided
* to accommodate the case where info text references an option by
* name/desc, and the desc/desc_categorized text for that option differ.
* If empty or NULL, the string specified by
* retro_core_option_v2_definition::info will be used instead.
* retro_core_option_v2_definition::info_categorized will be ignored
* if retro_core_option_v2_definition::category_key is empty or NULL.
* - retro_core_option_v2_definition::category_key should contain a
* category identifier (e.g. "video" or "audio") that will be
* assigned to the core option if frontend has core option category
* support. A categorized option will be shown in a subsection/
* submenu of the frontend core option interface. If key is empty
* or NULL, or if key does not match one of the
* retro_core_option_v2_category::key values in the associated
* retro_core_option_v2_category array, option will have no category
* and will be shown at the top level of the frontend core option
* interface.
* - retro_core_option_v2_definition::values is an array of
* retro_core_option_value structs terminated by a { NULL, NULL }
* element.
* --> retro_core_option_v2_definition::values[index].value is an
* expected option value.
* --> retro_core_option_v2_definition::values[index].label is a
* human readable label used when displaying the value on screen.
* If NULL, the value itself is used.
* - retro_core_option_v2_definition::default_value is the default
* core option setting. It must match one of the expected option
* values in the retro_core_option_v2_definition::values array. If
* it does not, or the default value is NULL, the first entry in the
* retro_core_option_v2_definition::values array is treated as the
* default.
*
* The number of possible option values should be very limited,
* and must be less than RETRO_NUM_CORE_OPTION_VALUES_MAX.
* i.e. it should be feasible to cycle through options
* without a keyboard.
*
* Example entries:
*
* - Uncategorized:
*
* {
* "foo_option",
* "Speed hack coprocessor X",
* NULL,
* "Provides increased performance at the expense of reduced accuracy.",
* NULL,
* NULL,
* {
* { "false", NULL },
* { "true", NULL },
* { "unstable", "Turbo (Unstable)" },
* { NULL, NULL },
* },
* "false"
* }
*
* - Categorized:
*
* {
* "foo_option",
* "Advanced > Speed hack coprocessor X",
* "Speed hack coprocessor X",
* "Setting 'Advanced > Speed hack coprocessor X' to 'true' or 'Turbo' provides increased performance at the expense of reduced accuracy",
* "Setting 'Speed hack coprocessor X' to 'true' or 'Turbo' provides increased performance at the expense of reduced accuracy",
* "advanced_settings",
* {
* { "false", NULL },
* { "true", NULL },
* { "unstable", "Turbo (Unstable)" },
* { NULL, NULL },
* },
* "false"
* }
*
* Only strings are operated on. The possible values will
* generally be displayed and stored as-is by the frontend.
