020 will be more compatible in future. Someday I'll connect 68020 A1200 accelerator to ACA500 which is connected to my logic analyzer A500 and use it to examine CPU timings, Motorola documentation does not really explain cycle usage very well. (A500 because it is 16-bit and does not use surface mount chips).

030 CE is 020 CE + 030 new features (write buffer, faster memory accesses, data cache).

MMU and cycle-exact can't be enabled at the same time. Maybe in future.

8x is the default because power of 2 clock rate multipliers (of DMA clock) are faster to emulate.
