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.

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.
