From the source:
    All games use a 6502 for sound (some are encrypted), all games except Cobracom
    use an Intel 8751 for protection & coinage. For these games the coinage dip
    switch is not currently supported, they are fixed at 1 coin 1 credit.

The issue described looks like a related issue: incomplete emulation of the 8751

If you invert the vblank bit polarity the continue feature works but then game's too slow.

Also if you have a 2 player game and either gets a game over game completely freezes for a moment.

MCU dump might help but it could be a race condition or even a btanb.
