Emulator

I'm new here and would like to ask about emulators:
do they understand unpublished assembler commands, such as (in HEX):
ED 44 , ED 45 , ED 4C , ED 4D ,
ED 54 , ED 55 , ED 5C , ED 5D ,
ED 64 , ED 65 , ED 6C , ED 6D , ED 66 ,
ED 74 , ED 75 , ED 7C , ED 7D , ED 67 , ED E7 ,
or
DD 25 , DD CB 80
...

PS: could anyone lather a good one emulator,
thanks in advance.

Regards Aleksandr.
