Make mouse cursor invisible

Hi! I'm curently emulating Mario Galaxy and I have the emulator setup to use my mouse as the pointer on screen to colect star bits.

However, I end up having both the game cursor and the system mouse cursor on screen at all times. In native PC games it would just hide the system mouse cursor and only show the in game one, but since this is an emulator it won't do that.

Is there any way to make the system mouse cursor invisible? I wanna keep the mouse functionality but make the system cursor invisible so it only shows the in game cursor when I'm moving the mouse around.
