Summary	08942: coolmini: Minigames don't work properly/softlock
Description	Starting in MAME version 0.194 and continuing to 0.270, there are at least 3 minigames in Cool Minigame Collection that don't work properly.
Steps To Reproduce	After adding a credit and starting the game, choose the minigame "Stop Thief!". Each of the 3 buttons throws a snowball at the bad guy coming out of each chimney, but the button that is supposed to throw at the middle chimney throws in the wrong direction, and if you press it enough times, it becomes impossible to continue throwing snowballs. In the minigame "Classroom", aiming at the top right corner causes the attack to miss and like in the snowball minigame, it becomes impossible to continue attacking. The minigame "Frog" also has a problem that prevents the player from moving, although I don't know exactly how you make it happen. It usually appears in the demo. All of these minigames work correctly in MAME version 0.193.
