From Chris:
In response to Applejuice's statement here:
So, regarding the power playfield feature. I think we need to check the rear of the swirl ramp in greater detail. There should be a switch mounted on there somewhere and also a diverter of some kind to allow the ball to enter the upper playfield instead of continuing up the ramp.
This switch is the one we now need to check in arcade game play as to whether that progresses the POWER lamps. Please also pay attention to what the screen says after switch hits. If it shows the messages under the score i posted earlier then we are good. If not then its time to get the 'fix this' list out..
"Thank you Jim for all of you efforts. Not ideal to be chasing answers without a game in front of you. So I think I can put an end to this Magna Flipper chase once and for all. Switches and lighting POWER do not matter. After stepping back and just studying the ramp and the mech it's clear as day: there is absolutely no way for the ball to be diverted from the left ramp into the upper Magna Flip playfield.
There is one diverted located on the upper right portion of the clear ramp. This diverter works. The ball either goes up the ramp with the diverter open which lets the ball loop around the front of the ramp and then drops the ball down the left squiggly ramp return to left flipper. If the diverter is closed the ball goes down the right squiggle ramp to the right flipper. There is absolutely no entrance to the Magna Flip playfield from the left ramp.
HOWEVER there is one entrance to the Magna Flip playfield. Through the hole in the middle of that playfield. Yes, the ball can enter that playfield from UNDERNEATH it. Which makes sense now because that explains why there is a diverter flap (black plastic flap) that covers the whole ABOVE the Magna Flip playfield. If the ball continued UP that whole it would reach the Mystic Ring Magnet which sits at the very top of the whole mech (right under the Genie's head).
Originally it seems John wanted the ball to be fired from the playfield UP through one hole (magna flip level) and then through another hole (mystic ring capture) where it would be suspended inside a magnet. Looks like he ditched that seemingly impossible shot and decided to make the coil shoot the ball up through one hole, hit the black plastic flap and fall into the Magna Flip playfield.
I think what this means Jim is new code is needed to make the Magna Flip entrance come from the coil shot on the playfield, not a ramp diverter. This all makes sense now why John contacted you back in November to help out. He had made chances to the mech so that it could work but had nobody to code in the new approach.
Good news is this...I think the center mech will 75% work...which is fine. John only needed to have the ball go in 3 different directions to make the game fun. Just like TOTAN. Ball can go left, right, or into the GENIE fireball throw. With MG, it looks like the ball can go left, right, and be fired up into Magna Flip area...that would make for a fun mech. He really bit off more than he could chew and tried to make too much happen in one area of the game. Hence the mountain mech that blocks half the screen and still will never physically work."
If any of you have any more questions I'm happen to make more videos going over stuff. Your obedient servant...CK
