    These games all have dipswitches, but they are mapped in such a way as to make
    using them with MAME extremely difficult. I might try to implement them in the
    future.

    Known problems:

    1 The games seem to run too fast. This is most noticable
      with the speech samples in Zektor - they don't match the mouth.
      Slowing down the Z80 doesn't help and in fact hurts performance.

    2 Cocktail mode isn't implemented.

    Is 1) still valid?
