The most notable differences are the lights are a different colour, and there's an invisible post at the bottom of the inner right ramp, which serves to deflect balls rolling down its right edge into the left flipper. Definitely makes things easier, but I'm not sure it looks physically plausible. Oh well - I think they didn't have much choice, it was ridiculously difficult beforehand. And maybe I'll get used to thinking of it as bouncing off the actual post built into the ramp...
