Thanks for the vote of confidence. Unfortunately we're a long way from there
right now :(

The code you were debugging could crash the debugger? Ouch. We're trying
to avoid that, at least... though there's a school of thought that says
it's better to crash than give wrong results. Of course, you don't always
have a choice (if you knew there was a bug there, you'd get rid of it..)

I hope so. Still, this debugger is probably only of interest to the
members of this list (are there any hardcore 2600 devs that don't read
it?), so we want to eliminate the limitations as people point them out...
assuming we can.
