retrotile_get_tiles_p

#define retrotile_get_tiles_p

(

layer

)

   ((retroflat_tile_t*)(((uint8_t*)(layer)) + \
   sizeof( struct RETROTILE_LAYER )))

retrotile_mstate_name

#define retrotile_mstate_name

Typedef Documentation

retroflat_tile_t

typedef int16_t retroflat_tile_t

Value for an individual tile in a RETROTILE_LAYER.

This is defined early on so that it can be used in some other modules.
