Thanks.

                                                    ^^^^^^^
A typo.  (There are several more like it.)

Also, I suggest to say "error 0x%s", not "0x%s error".  The latter is
confusing for the ears of an English speaker, I think.

Why the XXX in this comment?

Is this valid ISO C?

                                                                                           ^^^^^^^^^^
"at address".

By the way, do we need debug messages to be translatable?  Other
similar places in the patches don't have them in _().

> +      printf_unfiltered (_

                                          ^^^^^^^^^^^^^
"doesn't support"

By the way, what happens if the code stream includes one of these
``unsupported'' instructions?  What will the user see at replay time?
