RE: Technical Q converting scenarios
All you have to do is open them in the TOAW III Editor, then save; you can save right over the old .sce file if you like; it's then ready to go. The new editor saves it by default into the TOAW III "scenario" folder, so if you're not expecting that, you may wonder where it went...
And, you'll note the new .sce file, after conversion, is larger than the old one.
You need to remember to do this; if you don't, you can still open the old scenario in TOAW III, but it won't play right, the event engine will detect "errors", and the game will print an "event error text" message in your scenario folder, as a warning.
