Fixed. I snipped 6 wires in the middle and removed the 2 pressure plates that caused the signal to continue to the next half of the machine. Bottom levels "up" now goes to the middle, not to the very top, and vice versa.
Iirc in game, Alucard has to hold up or down to go up or down. So if he's at the bottom floor and hits up, the elevator takes him up to the middle, where it stops. If you are still holding up when it gets to the middle floor, the stop is brief, a short half-second and it then takes you to the top, giving the illusion it's an "all the way up" trip (because you held up when u entered, and when it hit the middle floor). I'm going to charge my PSP and load C:SOTN and play with the in-game elevator.
I could add 2 additional switches, at the top and bottom, for "all the down" and "all the way up", and put the 6 wire 2 plate "continue" crossover back in. Thoughts?
