Kick & Run - (c) 1987 Taito

Ernesto Corvi
ernesto@imagina.com

Notes:
- 4 players mode is not emulated. This involves some shared RAM and a subboard.
  There is additional code for a third Z80 in the bootleg version, I don't
  know if it's related or if its just a replacement for the 68705.

- kicknrun does a PS4 STOP ERROR short after boot, but works afterwards.
  PS4 is the 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 68701 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.
