...Thunder's post doesn't quite refute the arguments presented in the first post of the topic, no. Anyway.

First off, we have not found the source code. If you spend any time reading posts you'll notice that Openjazz is an original program using JJ1's data files but none of its code, as that is not available. As for making JJ1 levels, yes, that is always a good idea insofar as it goes, but unfortunately this topic is not going to provide much incentive for people to do so.
