  Hyper Pacman addition by David Haywood
   + some bits by Nicola Salmoria


Stephh's notes (hyperpac):

  - According to the "Language" Dip Switch, this game is a Korean game.
     (although the Language Dipswitch doesn't affect language, but yes
      I believe SemiCom to be a Korean Company)
  - There is no "cocktail mode", nor way to flip the screen.

Notes:

Cookie & Bibi 3
This game is quite buggy.  The test mode is incomplete and displays garbage
on the 'Dipswitch settings' screens, and during some of the attract mode
scenes the credit counter is not updated when you insert coins until the next
scene.  Both these bugs are verified as occuring on the original hardware.

Honey Doll / Twin Adventure

These appear to have clipping problems on the left / right edges, but this
may be correct, the sprites which should be drawn there are simply blanked
out of the sprite list at that point.. (verify on real hw)
