data cache emulation is very cpu intensive, so it's not enabled when neither "more compatible/prefetch" nor "cycle exact" are enabled.

this way you can get "fast" 68030 with MMU emulation if you don"t care about emulating cache (which should not affect programs, unless they really try to access/manipulate the data cache, which is rare)

Or program depends on more cycle-accurate CPU instruction emulation
e.g. when interacting with DSP.

The bottom line is that whatever setting / accuracy level you choose, data cache behaviour should not make the program crash.
