/* Driver Info


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

you get 64 credits in hwaction (eeprom bug?)
service mode doesn't work in hwaction (reads from unmapped memory, probably a mirror of something)
