Notes:

paradise: I'm not sure it's working correctly:

- The high scores table can't be entered !?
- The chance to play a bonus game is very slim. I think I got to play
  a couple in total. Is there a way to trigger them !?

penky: we need to delay the irqs at startup or it won't boot. Either one of
       ports 0x2003.r or 0x2005.w starts up the irq timer (confirmed via trojan)

PCB Layout
----------

Looks identical to the YS-0402 but has no number printed on the PCB
  For vertical games, Yun Sung would take a known board reprogram the
  Actel A1020B but not give the PCB a specific number.  This was also
  done for Yun Sung's game Paparazzi.  See yunsun16.c driver
