Kick & Run - (c) 1987 Taito

Notes:
- master/slave 4 players mode is not emulated at all.
  To set it up, enable the Master/Slave Mode and set the two boards IDs with
  different settings. Do NOT enable the Single board 4p mode, I don't think
  that the main board is supposed to be still connected to the sub board.

- Single board 4 players mode actually works but I'm not sure how the reset /
  halt line is truly connected on the sub cpu.
  To set it up, just enable the single board 4p mode and keep the master/slave
  mode to off and the board ID to master.

- kicknrun does a PS4 STOP ERROR shortly after boot, but works afterwards.
  PS4 is the MC6801U4 mcu.

- Kiki Kaikai suffers from random lock-up's. It happens when the sound
  CPU misses CTS from YM2203. The processor will loop infinitely and the main
  CPU will in turn wait forever. It's difficult to meet the required level
  of synchronization. This is kludged by filtering the 2203's busy signal.

- KiKi KaiKai uses a custom MC6801U4 MCU which isn't dumped. The bootleg Knight Boy
  replaces it with a 68705. The bootleg is NOT 100% equivalent to the original
  (a situation similar to Bubble Bobble): collision detection is imperfect, the
  player can't be killed by some enemies.
  I think the bootleggers put the custom mcu in a test rig, examined its bus
  activity and replicated the behaviour inaccurately because they coudln't
  figure it all out. Indeed, the 68705 code reads all the memory locations
  related to the missing collision detection, but does nothing with them.

- In the KiKi KaiKai MCU simulation, I don't bother supporting the coinage dip
  switch settings. Therefore, it's hardwired to be 1 coin / 1 credit.

- Kick and Run is a rom swap for Kiki KaiKai as the pal chips are all A85-0x
  A85 is the Taito rom code for Kiki KaiKai.  Even the MCU is socketted!
