While I cannot exactly duplicate your report, I can report some oddness happening only when Player 1 (left-red) had died and the Player 2 (right-green) has survived. I was able to complete the level I was on when Player 1 lost the last life, but on subsequent boards, once I got an energizer, the Player 1 shows as alive/appears on the top right of the screen and can be controlled by the Player 1 controls in a limited left-right area. I'd assume the program still thinks that the Player 1 is alive and started drawing and following the movements. My hunch is if this is not original behavior, the decryption may not be 100% correct. In any case, it is surely behavior that isn't expected.

I've attached a save state (k), for current MAME which, when you start it, sets up the condition where if you get an energizer, the Player 1 sprite appears on screen.

To TrevEB:
It would help to can create a Save State from 0.231 if you can replicate it again. Perhaps I just didn't set it up correctly.

It's almost certainly just a bug in the game. The whole thing is an elaborate hack, that feels very shaky, so overlooking of some logic cases isn't surprising.
