I haven't seen any collision with the supposedly invisible moving floor in any gameplay video in MAME.
Not even here with 4 players crossing it:


Could this be related with the difficulty dip switch of the game? I bet the moving floors will appear in hard/hardest mode.

if you could research that it would be appreciated, this is an unusual one, especially considering that the MCU *is* dumped and emulated here, which pretty much rules out it being a subtle protection issue.

Tested on mame 0.226, hardest difficulty.

The bug is there, and yes, the moving floor is invisible:


Confirmed!

it seems to work fine on quartet2a, the unprotected set. I wonder if there's actually a problem with the MCU dump or the hookup of it.
