There's a new version on the file server. There is no much change since last version though, at least if you do a quick look on it.
I've changed half of the code to keep the application just as it was before, but well, this kind of things happen

File handling has been fully recoded, and now save and save_as functionalities are enabled, and even seem to work.
I have recoded most of type-lists stuff: that means all selectable options in engine, freight, category and way type dropdowns. They are now configurable by external files and pak dependant. You can take a look on the files in the config folder.
I've also added a trivial and manual translation system, which consists on lists of internal_name;translated_name items. Again in external csv files. They're in the translations folder.
All other options haven't been tested yed, and may (or not) be recoded as well. I've done a couple of tests: I've created a simple (very simple) vehicle, and I was able to save it, and loaded it back without any problem. Anyway, I didn't try to compile it with makeobj

Again, it seems to load any pak128 objects and save them back; but that hasn't been hardly tested yet.
So you can download it (same link) to take a look, mainly at the editor window, but don't expect to mess a lot with it, as it is still in pre-beta status.
PS: Pak64 files haven't been changed yet; they're just pak128 copies!
