I've been looking around the PSIV code tonight, and the text is easier to find than I thought, though I've got a really awesome guide of all things PSIV: http://www.wrftpb.com/psiv/. That's got all kinds of data. It's too bad the guy that wants to make the editor is currently working on another project, because I'll be able to hunt down all the text in a week or so. I haven't found any unused dialogue yet, like in PSI, but there's some oddities.
Does anyone around here having much programming experience? If so, maybe someone will figure this out: ALL the PSIV level-by-level data, Character names, and Character Profession are in the code twice. My question is.... why? What an enormous waste of space! Though they don't seem to edit quite correctly. On one the experience needed to gain a level doesn't change if you edit the second level, on the other... it does, yet the data is identical. I'd love to know what's going on with it!
