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 couldn'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.
- KiKi KaiKai coinage mode Type 2 doesn't work.
- 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 socketed!
