But seriously, I'd highly advise you not to mess with calibration with the dualscreen exe.it's just simple maths : just be aware that for the real game, pointing the gun to the middle of your screen would mean.in the middle of the game screen so in the middle of P1 half-screen You have to select the one you want and you'll have a white square to shoot at, whereas the other player as a blackscreen. On gun settings menu, you have a line for each : '1P gun adjustment' and '2P gun adjustment'. Hmm weird.there's a crosshair for both players, what's why I made a no-crosshair patch (I hate this !). And, by the way, single screen mode works very weel too with single screen exeĢ. ALT+F4.or process kill by script, I didn't find something else.
