I need to make my mouse pointer a limit area, because I’m playing on a nintendo ds emulator and I need the mouse to stay over the emulator area while I play it. Step by step please, I’m noob with computers. ( I will choose best answers). (I really need this cuz when I play the beyblade game, I need to move the mouse very fast into certain areas, and I keep on getting the pointer out of the emulator).

If the emulator has the option of swithcing to full screen, then that’s your best chance, because otherwise it will be complex to you having the mouse controlled in just one area of the screen, and having an application controlling that will suck up system resources and thus possibly slow down your game and the whole system.
