Idea.  What it does is:

 ptr = (up[2] + up[3]) % 99 ...

- do, by chance, the first 4 bytes of "up" contain a long int and the code
is adding the two "low bytes" together?  I'm on a big endian machine
(PowerPC) and if that is so, this might need byte-swapping...

Just a random thought too late in the night :-)
