This is pretty easy since the saves are plain text. Open [name].sav in a text editor and scroll down until you see the inventory list. You’ll see something like:
I 100 pockknife -1 0 0 0 0 null -1 0 0 0 -1 -1 -1 ''
I 97 matches 20 0 0 0 0 null -1 0 0 0 -1 -1 -1 ''
W 97 jeans -1 0 1073741824 0 0 null -1 0 0 0 -1 -1 -1 ‘’
Which indicates I have a pocket knife and matches in my inventory and I’m wearing jeans. The (very long) line just above the first item has your character’s stats. Activate word wrap and look for a sequence like:
81 81 81 81 81 81 81 81 81 81 81 81 5000 0 5000 0 5000 0 5000 0 5000 0 5000 0 5000 0 5000
The 81’s are maximum and current hitpoints for various body parts and the 5000’s are temperatures for those body parts (yours will be different obviously, but it should be in that ballpark). Immediately after the temperatures are your skill values. Each skill has 4 numbers assigned to it. The first number always appears to be ‘1,’ I don’t know what the 2nd number is, the 3rd number is your skill level, and I think the 4th number is the % progress to the next level. Then it repeats for the next skill and so on.
Incidentally, immediately after the skills are your recipes and then bionics. Immediately before your hit points are a very long sequence of mostly 0’s (most likely) that are binary variables indicating which perks/mutations you have.
edit: I made a slight mistake. The 4th number is always a ‘1.’ There were 3 leading 0’s after the temperature values that were apparently for the “null skill” that got removed yesterday. But it should be easy enough to figure out what’s what if you’re looking at your character sheet in one window and the save file in another.
