Hello,
I wanted to get back into modding games for fun and I had a small project in mind.
I would like to edit my saves and change the Sims career advancements and skills.

I programmed a small IFF decoder and using the initial neighborhood files.
When comparing the files between User00005 (Jeff Pleasant) and User00009 (Mortimer Goth) I was able to find the GUID, but I cannot figure out where the skills and career data are.

19-OBJD (19 being the item number inside the iff) contain the GUID
20-STR# contains the outfits
26-CTSS contains descriptions
27-rsmp and 28-XXXX seem to be tables (per http://simtech.sourceforge.net/tech/rsmp.html and https://simstek.fandom.com/wiki/IFF#NBRS)

I tried opening neighborhood.iff just in case but it seems to be a long shot.
The block 1-NBRS might have skills and career data as I'm seeing the GUID?

If you have any pointer on where this could be stored, I would be very grateful.

Thank you for your help

I don't know how to find that in the .iff file.

If no one else knows, it might be a lot easier to edit your characters in game. There's an expanded set of cheats at https://modthesims.info/showthread....230#post5787230. And there are a number of mods that let you choose careers, give promotions, and so on. The Supersculpture at SomeSimThings will do some of what you want, and the career computers at https://sims1.aroundthesims3.com/ob...owntown_17.html will let you choose any job. My own hacked painting will let you add one skill point at a time, in any skill you wish, up to the maximum: http://corylea.com/Sims%201%20Hacke...ll%20Items.html

It sounds like what you want to do is possible with the paid SimEnhancer program. It can no longer be purchased successfully and hasn't been able to for several years, so here is an upload:

Thanks for sharing that!

Thank you both!
It's indeed very close to what SimEnhancer does. Worst case scenario I will run a diff on the files after running the program.
For adding cheat objects I found a few helpful links (Woobsha) from Reddit which could guide me through: https://www.reddit.com/r/sims1/comm...sims_1_objects/

That's my post, over on Reddit; I'm glad it pointed you toward some resources you found helpful!
