I've searched the boards here and have only been able to find posts about editing your stats and skills but nothing about editing items so I thought I'd post my hacking information for anyone that wants it. This first image is general information about where values are:
WeaponHack3 (389KB)
This image is an example of what your hacked item would look like. This item was the original worn knife you find in the room when you start a new game.

This image shows the hex values for the previous image.

If you know how to edit hex and have an intelligent question about how I hacked this item I'll be happy to anwser it. Otherwise I'll just ignore it.

I've also found that you can edit the base modifiers. Open global.cmp with a hex editor and switch to ASCII mode, then search for "begin item", the first item will look like this:
begin item
name "Knife"
slot Weapon
onehanded
maxshape 8
currentshape 8
numdice 1
dicetype 9
diceadd 3
itemlevel 25
minstrength 0
mindexterity 0
charm "Backstab"
charm "Dagger"
end item
If you change
numdice 1
dicetype 9
diceadd 3
to
numdice 100
dicetype 100
diceadd 100
Then every Knife you find will do 200-10100 damage. I've tried to edit this with notepad and wordpad but it doesn't save it correctly so you must use a hex editor to edit this file.
