I've thrown together a python script for decompiling sample.cat and recompiling it again, it ought to be portable across most of the systems that ottd runs on.

Ooh, Python. I also wrote such a tool a few years ago in C, not sure if I released the code or not, I have a feeling I may not have. Code from that is also included in TTDAlter (although in-memory decoding only, not encoding).
