There is no such thing as undocumeneted opcodes in 68k.
Unused opcodes there is, and undocumented flags for that matter.
You have 3 kind of exception caused by unused codes:
1, line-a: $Axxx codes causing this
2, line-f: $Fxxx
3, illegal: anything else

The problem with some protected games is more like nobody is willing to spend any time with those "games", so the amount of work involved cracking them is not really justified
