Kick Goal (c)1995 TCH
Action Hollywood (c)1995 TCH

 prelim driver by David Haywood


todo:

Sound - Not possible without PIC dump?
  the PIC is protected, sound will have to be simulated
  the kickgoal sound rom is also bad.

Should the screen size really be doubled in kickgoal or should the fg tiles be 8bpp instead
because otherwise these don't seem much like the same hardware..

Both games have problems with the Eeprom (settings are not saved)

   This table converts commands sent from the main CPU, into sample numbers
   played back by the sound processor.
   All commentry and most sound effects are correct, however the music
   tracks may be playing at the wrong times.
   Accordingly, the commands for playing the below samples is just a guess:
   1A, 1B, 1C, 1D, 1E, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 6A, 6B, 6C
   Note: that samples 60, 61 and 62 combine to form a music track.
   Ditto for samples 65, 66, 67 and 68.
