Some notes:
The item-list is not an exact science. Some values change their meaning depending on the area you are currently in. A dart can sometime be a stone, for example... could not find out how the devs decide what is what. But the useful items are almost always working, anyway.
The Hitpoints are "signed bytes", so 127 is the maximum health a character can get. 128 is MINUS 128, so it blows the character out of its shoes :ph34r:
Be warned about the script which fills the food-bar, this can have side effects. The more secure way is to just edit the values of all characters to 100 and freeze it
since this is an old-school game, there is no automapping. Which, in my opinion, adds to the feeling. However, if you'd like to have automapping, take a look at a handy tool called "The all-seeing Eye".
Edit: as found out by MightyAtom, you might have to add +D88 to character's offset if the character editor does not show you the correct data.
best regards and have fun,
