-
-// The mouse is a simple mouse, similar to Super Nintendo's mouse.
-// X and Y coordinates are reported relatively to last poll (poll callback).
-// It is up to the libretro implementation to keep track of where the mouse pointer is supposed to be on the screen.

-// Lightgun X/Y coordinates are reported relatively to last poll, similar to mouse.
-#define RETRO_DEVICE_LIGHTGUN 4
-
-// The ANALOG device is an extension to JOYPAD (RetroPad).
-// Similar to DualShock it adds two analog sticks.
-// This is treated as a separate device type as it returns values in the full analog range
-// of [-0x8000, 0x7fff]. Positive X axis is right. Positive Y axis is down.
-// Only use ANALOG type when polling for analog values of the axes.
-#define RETRO_DEVICE_ANALOG 5
-
-// Abstracts the concept of a pointing mechanism, e.g. touch.
-// This allows libretro to query in absolute coordinates where on the screen a mouse (or something similar) is being placed.
-// For a touch centric device, coordinates reported are the coordinates of the press.
-//
-// Coordinates in X and Y are reported as:
-// [-0x7fff, 0x7fff]: -0x7fff corresponds to the far left/top of the screen,
-// and 0x7fff corresponds to the far right/bottom of the screen.
-// The "screen" is here defined as area that is passed to the frontend and later displayed on the monitor.
-// The frontend is free to scale/resize this screen as it sees fit, however,
-// (X, Y) = (-0x7fff, -0x7fff) will correspond to the top-left pixel of the game image, etc.
-//
-// To check if the pointer coordinates are valid (e.g. a touch display actually being touched),
-// PRESSED returns 1 or 0.
-// If using a mouse, PRESSED will usually correspond to the left mouse button.
-// PRESSED will only return 1 if the pointer is inside the game screen.
-//
-// For multi-touch, the index variable can be used to successively query more presses.
-// If index = 0 returns true for _PRESSED, coordinates can be extracted
-// with _X, _Y for index = 0. One can then query _PRESSED, _X, _Y with index = 1, and so on.
-// Eventually _PRESSED will return false for an index. No further presses are registered at this point.
