It's good that you posted this, it reminded me of the message you posted on my profile. I didn't reply to it, because I wasn't sure if you'd even be notified about a message appearing in my profile, so I figured instead I'd simply dig up the editor you asked for and post about it. As it is, I haven't located the backup CD *yet*. It's here somewhere, though, because I don't throw out that kind of stuff - so hopefully I'll find it for you in a couple of days.With about 10 years of experience in professional software development I wouldn't consider myself junior grade.
Nonetheless, I have started gathering descriptions of data-files and started to work on a new editing tool (independently from the above quote, upon which I have just stumpled recently).
Keep in mind, my editor probably won't be that useful. As I recall, it's based on HCl's research, so there's a good chance you have most of this stuff already. All that was new to my work was that I was doing it in... Visual Basic, and therefore, it had a rudimentary visual interface. But hey, I'll post it anyway, maybe there will be something useful in it for you after all. In any case, it's definitely high time someone got to work on a real editor for these games .
