Say, I finally found this post you were talking about JS.
I just posted a new thread topic
http://slickproductions.org/forum/index.php?topic=864.0And I'm still looking into finding which data offsets effect the command routines, although I always find something else when looking for one thing.
I believe the data presented on the thread will be self explainatory and in proper grounping.
If not, then here's a hint:
Finding the data is tasky and fort night, the order of successfully finding in difficult levels are
(1)Info & used Item, (2)Parry/Change, (3)Item Select/Equip(4), (5)Spell Select, (7)Player/Enemy, and finally the Commands(10)
It seems there's more data references I have not found yet, but will soon collect them all. <-

I've done the Info/Used, Parry/Change(no need though), ItemSelect/Equip.
Working on SpellSelect, Player/Enemy(pointless, yet still useful).
And hopefully figure out the routine and combinations to make the commands happen!
