My own preference (from multiple experiences) is to do
some cleanup and
inspection, and then go straight to reverse-engineering - a long process
but you have some greater surety of eventual success and you have the
schematic for the next time it breaks. Here's my little tale of the
first time I did this:

That simulation of the Facit 1123 is downright beautiful! It took me a
bit to realize it was never going to work in Firefox, but once I
switched to IE it was great.
With the decimal point position set to blank, it did seem to get stuck
looping in state 31 forever when I divided 1 by 3. It could also be
that I have no experience whatever with this calculator and this
behavior is quite normal. :-) I found it curious that the only +
function is to memory, and I found the M+ and MR operation to not be
intuitive but that's probably just my ignorance as well. Again, this
was with the DP position blank; maybe that is just not intended or I
don't understand it's purpose.
I've bookmarked your website for future reference as I can envision
several other uses for that simulation language.
