Reverse engineering to C source is likely to be quite difficult )-:

Have all reasonable attempts been made to recover the code from the hard=20
drive? It is quite likely that such a recovery, if possible, will be the=20
cheapest alternative.

How much has the app changed since the last backed up revision?

What version of "C" is being used?

How big is the app?

What type of PIC is targeted?
