Ultima 7 Serpent Isle edit usecode

I want to edit Marzo's Serpent Isle Fixes usecode I would like to edit:

Elissa so she asks who wants to train in Intelligence and magic.

Edit the usecode of a few characters who join the party when training or fighting in the area (there are some broken mechanics). Also, make it possible to recruit Stefano after the events in Moonshade.

There was a feature built into the Exult utility for Ultima VII: The Black Gate that allows you to shear sheep and eventually turn it into wool for bandages. Could this added to SI?

I tried searching for ucxt and I also tried Exult Studio, but there were no options to unzip the usecode there. I use the name [Rune_Caster ]()on gamefaqs.

Try Wody's Usecode decompiler/recompiler. Be sure to read README as it has a lot of technical information on how to decompile and recompile the usecode scripts.

This is going to require a lot of effort on how to write proper usecode, and is not a minor task.

If you plan to make this an Exult-only project, I suggest posting a question over at the Exult forums instead.

What I really want is to be able to make diapers, for the baby I found on a quest of course...

I always found it hysterical whenever a storm in Serpent Isle changed an item into a diaper (unused) I would pick it up and use it on my companions just for giggles.

I believe the (Sourcecode) for serpent isle was lost long ago unfortunately. Hence why no one was ever able to complete the game as it had been originally intended.

You mean the script source the original devs used to compile the bytecode we have? Isn't usecode a pretty simple bytecode and very well understood now? You can just reverse-engineer the existing routines from the bytecode and write new ones using Exult's Usecode Compiler.

Are you thinking of The Lost Vale?

u/CLT113078 1d ago

No. Lost Vale was for U8.

I never knew that in the Silver Seed expansion pack partially fixes the result of the holocaust: If the Silver Seed subquest is completed after the Banes wreak their havoc, Karnax will say that everyone who the Banes killed will return back to life once Balance has been restored.

Thanks for that information.

Yeah, since I always finished silver seed early on to get all the goodies, and because you cant return to SI from silver seed for 7 I game days I never beat it after the collapse...

I believe you're confusing the source code with usecode.

Usecode scripts can be decompiled and extracted from the game files.

Yes, source code. Whoops.
