6502 illegal opcodes

Hi,

In my cbm 8032 emulator I'm planning to have some support for illegal 
opcodes

I saw 3 type of illegal opcodes

-  nop,   no visible action
-  hlt      kill the cpu
-  xxx     have an action

are they reliable from a 6502 to another  ?  (for example   mos vs 
rockwell vs synertek)
or between 6502, 6509, 6510 ?

I'm planning to support non and halt
and let the others not processed (my be in a futur version).

any idea  ?
