Ouch, thanks!
That does NOT sound like something that I can easily parse any further with my crude bash one-liners
And it explains why my experiments with cmp & diff lead nowhere - even freshly started vanilla savegames are too different in their structure to recognize the difficulty settings (without more pre-processing beyond the deflation). From the sound of it, someone who's used to working with yml shouldn't have too much trouble to write a simple de/reencoder as a first step... mmmh... at least if it was one consistent format... and I'm not entirely sure it is... there are big chunks that look very different from each others (like the small String on the top... then the bigger part with the chunks of "FF xx xx xx"... then something that looks rather arbitrary...) and I can't find a delimiter or anything for those that would suggest that they are part of a overlying order instead of just mashed together one... Argh. Could just be a memory-dump-like stream after all for all I know T_T
On top of that, the game seems to be very rather wasteful though when it comes to writing stuff into the saves - there seems to be a lots of creature / map / script data in there (that I would have expected to be loaded from the game data files, not from the game saves). Maybe that's supposed to ensure that savegames still work after updates... it explains the need to start a new game to get the fixed stats for items after the patch. Also that makes it entirely possible that changing the difficulty mid game won't be a viable option (have not managed to isolate difficulty related creature stats yet, but the presence of those alone means that the difficulty setting could already be in there instead of just in one valua :/ ).
Guess I'll try to find the creature speed somehow (my main problem with the easy difficulty is that mobs just stand around looking stupid for so long), maybe I can change that with brute force... and a lot of luck... somehow...
edit: Oh, now I see those big nested chunks (STATS etc). So, It's not as much of a mess as I intitially thought after all... but still waaaaay over my head.
edit: yay, at least I've been able to change the name/portrait of the one guy that I forgot on creation. That's been bothering me too although not as much as the difficulty :3
