I don't think it is necessarily coded into the game. When the SDTM from the magnet conversation comes up there are a few people that believe hitting the flippers changes how the magnet reacts and moves the ball in different directions. People have also said rotating the magnet changes the direction the ball will be thrown to eliminate the SDTM. When I owned the game I tried them all and sometimes it would work and sometimes it wouldn't. I really liked the game, but there were 2 or 3 things that frustrated me so much (3 drop targets on the left that wouldn't always go down when hit) I had to get rid of it before I took a sledge hammer to it.

No shooter lane groove
Shots that go to nowhere
Areas of the playfield that a ball can't get too
The game is unplayable, for the most part, when it was first shipped.

I'm sure there are more, but the fact it doesn't have a shooter lane groove is one of the most obvious issues.
