The biggest tip for Capcom/Coors Light Bowling: PLAY WITH THE KEYBOARD!
It's a heckuva lot easier to get precise control of the ball with arrow
keys than with a trackball. Play with the trackball only if you've
mastered the game with the keyboard or if you want a true arcade
experience. To get a strike most of the time, position the ball between
the 3rd and 4th dots behind the foul line. Also, move the ball closer
to the foul line, but do NOT cross it. The closer you move the ball to
the foul line, the more you may need to nudge your ball a little to
the left. This is because when the ball travels slow enough on the lane,
it will hook to the right.
If the ball is over the line when you position your ball, and you have
not thrown it, you can move it back behind the line with no foul (which
is necessary if over half of the ball is across the line...a foul will
be called if you try throwing it from that position)
