Even in C you can have structures for that, i.e. 
typdef struct  { unsigned char data[240][240]; } data_t;
You'd even gain "assignability" that way.

Anyway. I see three options:

(a) Actually use a struct like above in your code and write a dumper for it.

(b) Add that struct definition to your code, write a dumper for it, and 
    when in need of inspecting the data, use an Expression Evaluator on
   *(data_t*) &your_data;  (or {data_t} your_data;

(c) Hack your dumper into the "if type.code == ArrayCode:" blob in
   dumper.py, recognize your special situation and fall back to the
   existing implementation when needed.

I think (a) is cleanest and least maintenance/usability effort in the long
run, but would mean touching your code.
