The emulation of Bubble Bobble is already virtually perfect, but there is still a doubt about the clock item.
Currently, when you pick it up the enemies stop but the bubbles continue moving.
It would make sense if the bubbles stopped moving too, and this idea is corroborated by the way variables are set up in the MCU shared RAM. The MCU would be responsible for stopping the bubbles and make them start again when the clock effect ends.
What we need is to verify the behaviour on an original board. Bootlegs don't count (the clock behaviour is definitely wrong in them), nor do other emulator or ports count. Only the original board matters.
Can anyone help?
