Xeen Save Game Editor

Let me know what you think!

Looks better than anything I've come up with. Are you looking up MAZE.CHR and MAZE.PTY files from the save file, or are you just assuming a static location in the save file?
Two things I've noticed though:
1) Gold and gems are unsigned long. They go from 0 to 4billion. You've got them signed, so max is only 2billion. Anyone with more than that it will display a negative number. Both gold in hand and in bank.
2) You've got stats as 2 byte integers, max of 32K. They're actually two 1 byte integers. Base+bonus. They can have a maximum of 255 each. That goes for all stats, might, intellect, etc... as well as elemental resistances, and level. You can reach a maximum of level 255, plus a bonus of 255.
Very well done with the items list, by the way. That was always a tricky one.

I am assuming static offsets based on info from the Darkside UGE module -- so this would be valid only with the original version and not the "speech" version. [ I found the Xeen wiki a few days ago.... and I didn't want to start over :-) ]

I have corrected the gold/gems/stats (and overlooked the resists) -- thank you!
v0.9.1

Pretty cool. If you want some help, just ask. I've got pretty much all the information on the wiki and then some in my head. :)
Just having trouble using it. I've been trying to make a map and script editor with some success, but I'm no GUI developer. It's slow going, painful to work on, I keep putting it off because it isn't fun for me to do, and even what I have is ugly. :(
