Function EnableSnesMouse

Prototype	void EnableSnesMouse(unsigned char spriteIndex,const char *spriteMap);
Description	Activates the SNES mouse support and starts keeping track of the mouse movement and drawing the cursor on the screen.
Parameters	spriteIndex: The first sprite index from which to apply the map. spriteMap: A regular map that contains sprites tile indexes.
Returns	Void
Video Modes	All
Since	V3
Notes	The SNES mouse is very slow to settle and the current implementation is not very efficient so it takes about 2.5 scanlines to fetch the extra X/Y axis bits.

Example:

#include "data/cursor.inc"
#define MOUSE 2 
...
//If there's a mouse connected to the second port, activate it
if(((DetectControllers() >> 2) && 0x3 == MOUSE) {
   EnableSnesMouse(0,map_cursor);
}
