How can i do for disassembling the usecode file with wud?What's the correct syntax to use?I have tried "wud -s -a usecode" but doesn't work!

The syntax is:

wud -s usecode -a (for serpent isle's usecode)

or

wud usecode -a (for black gate's usecode)


As an aside, please remember to specify _exactly_ why something doesn't work. There's no way we can figure out what is wrong when you simply say "It doesn't work"

Also in CVS, SharpTooth/Darke has been working on ucxt, a much more powerful alternative to wud.

Thanks!now im able to view the file, but if i want save the result in file for modify and then recompiling with wuc?

I wouldn't advise that you attempt to recompile usecode using wuc. It requires that you have all the offsets numbered correctly to work. Any changes to the usecode will change the offsets.

I was not able to get the output of wud to recompile with wuc. Some of these tools are not really supported, ucxt is much better. Soon with ucc and ucxt you will be able to code in a C-like script.

I believe you also need to use mklink to regenerate the linkdep files.

However SB-X is correct: ucxt and ucc allow the use of our homebrew ExultScript, which will be much easier that working with the usecode bytecode.

UCDUMP is self-explaining, though does not support SI (it will decode the intrinsic functions wrongly, the bytecode itself is fine).

UCDUMP source comments contains some info about innerworking of the game.
