// SSNES extension. Not required to be implemented for a working implementation.
#define SNES_ENVIRONMENT_GET_FULLPATH 0 // const char ** --
// Full path of game loaded.
//
#define SNES_ENVIRONMENT_SET_GEOMETRY 1 // const struct snes_geometry * --
// Window geometry information for the system/game.
//
#define SNES_ENVIRONMENT_SET_PITCH 2 // const unsigned * --
// Pitch of game image.
//
#define SNES_ENVIRONMENT_GET_OVERSCAN 3 // bool * --
// Boolean value whether or not the implementation should use overscan.
//
#define SNES_ENVIRONMENT_SET_TIMING 4 // const struct snes_system_timing * --
// Set exact timings of the system. Used primarily for video recording.
//
#define SNES_ENVIRONMENT_GET_CAN_DUPE 5 // bool * --
// Boolean value whether or not SSNES supports frame duping,
// passing NULL to video frame callback.
//
//
#define SNES_ENVIRONMENT_SET_NEED_FULLPATH 6 // const bool * --
// Boolean value telling if implementation needs a valid fullpath to be able to run.
// If this is the case, SSNES will not open the rom directly,
// and pass NULL to rom data.
// Implementation must then use SNES_ENVIRONMENT_GET_FULLPATH.
// This is useful for implementations with very large roms,
// which are impractical to load fully into RAM.
//
#define SNES_ENVIRONMENT_GET_CAN_REWIND 7 // bool * --
// Boolean value telling if SSNES is able to rewind.
// Some implementations might need to take extra precautions
// to allow this as smoothly as possible.
//
#define SNES_ENVIRONMENT_GET_VARIABLE 8 // struct snes_variable * --
// Interface to aquire user-defined information from environment
// that cannot feasibly be supported in a multi-system way.
// Mostly used for obscure,
// specific features that the user can tap into when neseccary.
//
#define SNES_ENVIRONMENT_SET_VARIABLES 9 // const struct snes_variable * --
// Allows an implementation to signal the environment
// which variables it might want to check for later using GET_VARIABLE.
// 'data' points to an array of snes_variable structs terminated by a { NULL, NULL } element.
// snes_variable::value should contain a human readable description of the key.
//
#define SNES_ENVIRONMENT_SET_BATCH_LOAD 10 // const bool * --
// If true, the implementation will load several roms in batch.
// This means the rom must be provided exactly as is, i.e. it cannot be extracted.
// If supported, this must be called directly when snes_set_environment() is called.
// (Used on consoles).
//
#define SNES_ENVIRONMENT_SET_ROM_FORMATS 11 // const char * --
// Sets rom extensions the core generally supports.
// If supported, this must be called directly when snes_set_environment() is called.
// Formats are delimited with '|', i.e. "foo|bar|baz".
// (Used on consoles).
//
#define SNES_ENVIRONMENT_SET_MESSAGE 12 // const struct snes_message * --
// Sets a message to be displayed in implementation-specific manner for a certain amount of 'frames'.
