Is there any place to get those Hardware Traces?
As it seems to be quite rare to find what the CPU actual does every clock (even Machine Cycles).

How come some instructions need decoding that takes 4 cycles?
For CB i get it, i assume it takes 4 cycles to read the next 8 bits, and then 4 cycles to execute it (if it's on a register only).
