射擊遊戲都有準星校準
Hit 9 (Service SW) + F2 (Test SW) to enter gun calibration. Hit LEFT ALT two times then aim for the target, using LEFT ALT to shoot, lining up your shot. Test to see that the target is aligned then hit 9 (Service SW) and then F2 (Test SW) to write NVRAM and return to game. It's suggested you fully restart the game after this step as there is sometimes left over target graphics from procedure.
