Mouse support

OK, usage goes like this:

snes_mouse has to be turned on (snes_mouse = 1). This is set 0 by default after consoleInit().
This will tell the system to read from a mouse, if it is found.
Mouse and pads can be used simultaneously, on any ports. Externs in the pad.h file goes like this:

snes_mouse; /*!< \brief 1 if Mouse is going to be used */

mouseConnect[2];        /*! \brief 1 if Mouse present */
mouseButton[2];         /*! \brief 1 if button is pressed, stays for a bit and then it gets released (Click mode). */
mousePressed[2];        /*! \brief 1 if button is pressed, stays until is unpressed (Turbo mode). */
mouse_x[2], mouse_y[2]; /*! \brief Mouse acceleration. daaaaaaa, d = direction (0: up/left, 1: down/right), a = acceleration. */
mouseSpeedSet[2];          /*! \brief Mouse speed setting. 0: slow, 1: normal, 2: fast */

the number inside array specifies port (0 or 1).
I recommend using this code structure to convert raw acceleration into usable values:

u16 p1_mouse_x = 0x80;
u16 p1_mouse_y = 0x70;
u16 p2_mouse_x = 0x80;
u16 p2_mouse_y = 0x70;

 if (mouse_x[0] & 0x80)
    p1_mouse_x -= mouse_x[0] & 0x7F;
else
    p1_mouse_x += mouse_x[0] & 0x7F;
if (mouse_y[0] & 0x80)
    p1_mouse_y -= mouse_y[0] & 0x7F;
else
    p1_mouse_y += mouse_y[0] & 0x7F;

All other aspects are specified inside the example ROM. Happy mousing!

Hi @DigiDwrf

Have you tested mouse support with the Hyperkin optical mice as well as the Nintendo mouse?
