Chad, almost all the Mess packages have the debugger.
The debugger must be turned on after mess is started (or from the cmd line), but before you run the Coco emulation. So, starting Mess from RainbowIDE will not allow you to use it, unless you run Mess before hand and turn the debugger on before you exit, or set RainbowIDE's Mess cmd line parms.

In the console versions, the debugger is activated via cmd line parameters. I don't use it this way, so I can't tell you how that's done. This method could probably be used in RainbowIDE as you can edit the cmdline parms in the IDE settings. It's easiest to use the debugger in MessUI. With the MessUI version, you just right-click on the Coco, selcet "Properties" then the "Debug" tab, then set it how you want it. The debug comes up in it's own window showing the currently executing code.. in 6809 ASM format & binary (much like EDTASM's ZBUG) :-)
You can set break points, single step etc.


 It's a pretty powerfull debug tool for sure :-)

Where can i find a good M.E.S.S. package with the debugger.  I have the
  
M.E.S.S. emulator in my Rainow IDE but I dont see any debuggers so I
   guess
I'm missing something.  Will the debugger allow me to step
   through the
code?

   Can't recommend this approach highly enough.
I've spent hundreds of
   hours in the MESS debugger over the years... no not
_always_ searching
   for bugs; sometimes it's for reverse-engineering purposes!
