Haha, nice find. Seems the lea
opcode only has problems with a5
as source register ;)
For bchg
, 68000 user's manual pg. 136 says for dynamic, memory 8 + EA (=10). So I would say, EASy68k is wrong, it seems to take from the column static, memory but that refers to something like bchg #3,(a4,d3.w)
.

My code just got faster :)
Love the new additions but some of the cycle counts seem wrong.
This should be 8 cycles not 18, I think:![image](https://user-images.githubusercontent.com/5326134/167733224-a12de879-4182-4690-9216-5c93f1fe3631.png)
This also seems wrong, EASy68k reports 22cycles:![image](https://user-images.githubusercontent.com/5326134/167734973-0205389b-b12e-4c00-85d8-b6f4c00382f3.png)
I don't know these numbers well, so I'm going off what EASy68k tells me. I suppose it could be wrong in the second case.
